Calculating Infrared Inspection Program Payback
Calculating savings and/or avoided costs is one of the most difficult tasks associated with an infrared inspection program; however, doing so is required in order to gauge how effective a program is.
In short, there is no way to calculate the exact value of the findings of an infrared inspection other than allowing the component run to failure and adding up the subsequent losses. Unfortunately, this is not a practical approach to maintenance.
As an alternative, there are several methods that professionals use to estimate program savings. A brief description of each of the most common methods is listed below:
1. Summary of Findings – A report comprised of the deficient items found during a given time period. Reports may be by the day, month, year, etc. This type of report does not provide any financial data.
2. Performance Effectiveness Ratios – Use accounting data to trend how an infrared inspection program impacts an overall maintenance program. Typically calculated for a single facility over an extended period of time. Improvements in efficiency can be compared to similar facilities or to the performance history of the subject facility.
3. Avoided Costs Method – A summary of the estimated cost of repairs for breakdown versus proactive repair efforts. Typically, proactive repairs are always cheaper since the outage can be planned and the cost of the actual repair is usually less since the subject equipment often suffers far less damage when not allowed to run to catastrophic failure.
4. Permanent Improvement Method – This is a summary of the financial impact on a given facility due to the implementation of an infrared inspection program. For example, infrared can be used to supplement a maintenance program by directing repair efforts to only those areas in need of attention rather than periodic application of labor-intensive manual work. In such cases, the cost difference between the two methods results in a savings every time the manual maintenance procedure is avoided in the future.
5. Statistics Based Method – This method is based upon insurance industry statistics associated with loss claims that have been paid to clients over a several year period. This method takes into account the value of the overall facility along with the severity of the problem. While this method is not as accurate as the Avoided Cost Method, it can be applied quickly and easily with a minimum of effort. Infraspection Institute’s Exception® Pro software utilizes this method for calculating savings as one of its standard features.
Each of the above methods varies in the information provided as well as the ease of use and accuracy. We cover each method in depth in our Level III Certified Infrared Thermographer Course.
When calculating savings, we recommend that thermographers consult with their end user and choose one of the above methods that will best suit his/her needs and consistently apply the chosen method over time. While you will not be able to calculate savings exactly, you should obtain a good indication of the value of your program.

The Best Recommendation
Tip written by: Infraspection Institute
As part of their infrared inspection reports, thermographers frequently include exception diagnoses along with recommendations for repair. In this Tip, we offer our suggestion for the only recommendation a thermographer will ever need.
When used as a tool for Preventive/Predictive Maintenance, thermography can detect and document evidence of thermal patterns and temperatures across the surface of an object. The presence of inexplicable thermal anomalies is often indicative of incipient failures within inspected systems and structures. Because thermography alone cannot determine the cause of an exception, other diagnostic tools must be employed to determine the cause of observed exceptions.
Although thermography is inconclusive, thermographers frequently provide opinions as to the cause of exceptions without having the benefit of confirming test information. Such opinions are frequently accompanied by elaborate recommendations for repair. When such observations/recommendations are incorrect, they can cause repair efforts to be misdirected.
Unless a thermographer has performed, or has access to, confirming tests, providing opinions regarding the cause of exceptions and subsequent recommendations for repair is unwise. When confirming test data are unavailable, a prudent thermographer should make only one simple recommendation: “Investigate and perform appropriate repair”.
Generating standards-compliant reports is one of the many topics covered in the Level I Infraspection Institute Certified Infrared Thermographer® training course.

Infrared Training – Why It Isn’t All the Same
Tip written by: Infraspection Institute
With interest in thermography at an all-time high, more people are seeking training and certification. When comparing infrared course offerings, many mistakenly assume that all training and certification courses are the same.
The greatest limitation in an infrared inspection is the thermographer. Because of this, thermographer training and certification have long been recognized as requirements to help ensure accurate inspections. To this end, several firms offer Level I, II, and III training courses; however, these courses are not equal.
The American Society for Nondestructive Testing document, SNT-TC-1A outlines suggested topics for training and certifying NDT personnel in the Thermal/Infrared Testing Method. Suggested topics range from basic theory and camera operation to advanced thermographic applications. Since these topics are suggestions, companies have wide latitude in compiling course content. Because of this, one should never assume that courses bearing the same name will contain similar content.
When considering any infrared training course, be certain to:
- Review course curriculum carefully to ensure it meets your needs
- Ascertain type of certification provided and its expiration date
- Consider the history of the training firm and its credentials
- Determine if courses are available via Distance Learning
Lastly, beware of training courses offered by equipment manufacturers or “vendor neutral” instructors. Only an independent training firm can offer unbiased opinions with respect to equipment choices.
For over 40 years, Infraspection Institute’s Certified Infrared Thermographer® training courses have set the industry standard for excellence. Students may choose from open enrollment classes or our convenient Distance Learning program. All courses are taught by field-experienced Level III practicing thermographers.

How Delta T’s Understate Priorities
Tip written by: Infraspection Institute
For years, thermographers have traditionally reported apparent Delta T measurements when documenting their findings. Using a default emittance value between .8 and 1.0, apparent temperature measurements are recorded regardless of actual target emittance. While this methodology is fast and easy, it can lead to significantly understated Delta T repair priorities.
The temperature displayed by a radiometer is largely dependent upon the emittance and reflected temperature values entered into the radiometer’s computer. Typically, errors in either of these settings will cause temperature measurement errors that are exponential in nature and can cause large errors in reporting Delta T’s.
Example: Using an emittance value of 1.0 a thermographer measures the apparent Delta T between two, uninsulated electrical bus bars to be 44ºC. How much can observed temperature vary due to emittance values?
From the above, the following observations can be made:
- Emittance can have a significant impact on Delta T measurements
- The greater the variation between an object’s true emittance and radiometer settings, the more understated the Delta T
- Repair priorities may be significantly understated if accurate emittance values are not utilized
As there is no way to correct for errors introduced by apparent Delta T measurements, thermographers should utilize correct emittance values whenever possible. As always, all thermal anomalies detected during an infrared inspection should be investigated and proper corrective measures undertaken as soon as possible.

Infrared Inspection of Capacitors
Capacitors are devices commonly found in AC electrical distribution systems where power factor correction is required. Like any electrical component, capacitors need to be regularly checked for proper operation. Infrared thermography can be used to rapidly inspect capacitors from a safe, remote distance.
Capacitors are wound devices that are electrically connected between potential and ground. Capacitors used for power factor correction are generally encased in painted, rectangular steel canisters and often have two equal sized bushings for electrical connections. In a three phase circuit, there may be several capacitors connected to each phase.
The most common failures of capacitors are loose/deteriorated bushing connections, open circuits due to internal winding failure, and open supply circuits. When inspecting capacitors, be sure to:
- Visually inspect capacitor bodies. Capacitors should not be misshapen/swollen.
- Thermographically inspect capacitor bodies. Capacitors should be warmer than ambient air temperature and exhibit equal temperatures across all phases.
- Check bushing and wiring connections for hotspots.
Any thermal anomalies detected should be investigated and corrected as soon as possible. Capacitors operating at ambient temperature should be corrected immediately as imbalanced capacitance can be more detrimental than having no capacitors at all.
Infrared inspection of electrical distribution systems is one of the many topics covered in the Level I Certified Infrared Thermographer® training course.

IR Inspections to Detect In-floor Heating System Leaks
Hydronic in-floor heating systems are well known for the comfort they provide. Under the proper conditions, thermal imaging can be used to help find leaks that develop in these systems.
Hydronic in-floor heating systems are one option for providing heat to occupied spaces in homes and buildings. A type of radiant heating, hydronic in-floor systems are constructed with rigid or flexible tubing that carries hot water or other fluids below the surface of floors. The heat flowing through the tubing is conducted to flooring materials which radiate heat to occupied spaces above the floor.
In framed construction, radiant tubing may be suspended underneath subfloor materials. It may also be installed above the subfloor by embedding it within engineered plywood panels that have grooves to hold the tubing. Another popular construction detail involves embedding the tubing within concrete slab flooring.
Over time, hydronic systems can develop leaks. For framed construction or installations where tubing is embedded in plywood, finding a leak can be fairly straightforward. For systems embedded within a concrete slab, pinpointing the source of a leak can be nearly impossible.
By using a thermal imager while the system is under load, it is possible to detect thermal anomalies created by leaks from radiant tubing embedded in a concrete slab. Such thermal anomalies appear as amorphous hot spots which tend to flare around the regular straight lines created by the pathway of tubing that is not actively leaking.
To help ensure accurate results, it is best to begin with the heating system off and the slab at or below ambient temperature. A load should then be applied to the system by adjusting the building’s thermostat to call for heat. As the system begins to heat the floor, a thermal imager is then used to inspect the top surface of the floor in an organized fashion.
Depending upon one’s circumstances, it may take up to a half hour or more for thermal patterns to emerge and become clear. It is recommended that imaging begin shortly after the radiant system is activated and continue until clear thermal imagery is seen for all subject areas. Best results will be obtained when flooring is not covered with thick materials such as carpet or wood planks.
During imaging one may see slightly warmer areas where tubing is spaced close to adjacent tubes or has not been buried as deeply as other tubing. Areas exhibiting thermal anomalies should be invasively tested to confirm the presence of leaks.
Thermal imaging of radiant in-floor heating systems is an application that is covered in all Infraspection Institute Level I training courses. For course locations and dates or information on our Distance Learning program, visit our website or call us at 609-239-4788.

Determining Acceptable Load for Electrical Circuits
Tip written by: Infraspection Institute
Infrared thermography is a useful tool for detecting heat patterns caused by overloaded electrical circuits. In this Tip we discuss what constitutes an acceptable load.
Infrared imagers are capable of detecting thermal patterns associated with several electrical deficiencies including overloaded circuits. When viewed with an imager, overloaded circuits will appear warm throughout their entire length with no discrete hot spots. Since it is not possible to determine circuit load from a thermal signature, actual circuit load must be measured with an ammeter.
Once circuit load is known, a question that frequently arises is, ‘How much load is acceptable?’ The answer to this question can be found within the National Electric Code 220-10(b) which provides guidance for circuit loading.
- (b) Continuous and Noncontinuous loads. Where a feeder supplies a continuous load or any combination of continuous or noncontinuous loads, the rating of the over-current device shall not be less than the noncontinuous load plus 125 percent of the continuous load. The minimum feeder circuit conductor size, without the application of any adjustment or correction factors, shall have an allowable ampacity equal to or greater than the noncontinuous load plus 125 percent of the continuous load. NOTE: Exception: Where the assembly including the over-current devices protecting the feeder(s) are listed for operation at 100 percent of their rating, neither the ampere rating of the over-current device nor the ampacity of the feeder conductors shall be less than the sum of the continuous load plus the noncontinuous load.
In other words, for most circuits load should not exceed 80% of conductor ampacity or 80% of the overcurrent device rating. To help ensure accuracy, electric loads should be measured with a true RMS sensing ammeter.
Infrared inspection of electrical equipment is one of the many topics covered in the Infraspection Institute Level I Certified Infrared Thermographer® training course.

Infrared Inspections to Detect Process Piping Corrosion
Tip written by: Infraspection Institute
Infrared thermography offers good potential for detecting energy losses from process equipment and piping as well as some symptoms of pipe deterioration.
It is important to remember that thermography is a line-of-sight technology that detects thermal patterns and associated temperatures across the surface of an object.
Subsurface characteristics or defects cannot be detected by thermography unless they cause a temperature differential of at least 0.1 Celsius degrees across the surface of the object being inspected. Presently, interior corrosion detection is best detected with ultrasonic thickness testing; exterior corrosion may be detected by visual examination.
Thermography may prove useful if corrosion is being caused by water saturated insulation surrounding your process piping. If this is the case, water saturated insulation should show excess energy loss at the point where the water is entrapped. It will be necessary to visually inspect the pipe to confirm the actual condition of the pipe.
When performing thermal imaging, be aware that weather conditions such as solar gain, wind and atmospheric attenuation can adversely affect your results. Be certain that your imaging system is capable of detecting the anticipated defect by understanding how emissivity, spectral response and spot size will affect your inspection.

Emissivity Settings for Building Inspections
Tip written by: Infraspection Institute
A common question among thermographers who perform infrared inspections of buildings is, “What emissivity setting should I use?” While this might seem like a straightforward question, the answer is not that simple.
Recent years have seen a dramatic increase in the use of thermography as a building diagnostics tool. While many applications are qualitative, there are occasions when quantifying temperature can be useful. In order to accurately perform non-contact temperature measurements, one must input the correct emittance value into a radiometer’s computer.
While many equate emissivity to values published in emittance tables, emissivity is a dynamic characteristic that is influenced by several factors. These include: wavelength, object temperature, viewing angle, target shape, and surface condition. Each of these factors can vary between projects or during a given inspection.
Further compounding the challenge is the fact that not all imagers are created equal. Imagers lacking corrective inputs for atmospheric attenuation and/or reflected temperature often require an exaggerated emittance value be utilized.
When performing an infrared inspection of buildings, keep the following in mind:
- For qualitative inspections performed with an imaging radiometer, leave the imager’s E control set to 1.0. If possible, turn off all temperature measurement tools.
- In general, dielectric materials will have a relatively high emittance; shiny surfaces and glass will be quite reflective.
- Viewing angle and reflected temperature can greatly influence the effective emittance of a material. In particular, smooth-surface roof membranes and building sidewalls can be quite reflective when imaged at low viewing angles often associated with ground-based inspections.
Lastly, emittance values obtained from published tables can introduce significant temperature measurement errors. Whenever possible, one should calculate emittance values with the subject imager and cross verify observed temperatures with contact thermometry.

Should Infrared Thermographer Certification Expire?
Tip written by: Infraspection Institute
If you’ve never noticed an expiration date on a college or high school diploma that’s because there isn’t one. Although educational diplomas are traditionally issued for the life of the student, the same is not necessarily true for infrared thermographers.
For several years, certain infrared training firms have issued diplomas or certifications that bear expiration dates. In order to keep one’s certification ‘valid’ with such firms, students must recertify by paying a fee and meeting other criteria that have nothing to do with the issuance of the original diploma. According to the American Society for Nondestructive Testing document, SNT-TC-1A, recertification of NDT personnel is required every 5 years; however, this is the responsibility of the individual’s employer. Such recertification is based upon an employee’s demonstrated proficiency. It is not based upon their ability to pay a fee to a third-party training firm.
For over 40 years, Infraspection Institute’s Certified Infrared Thermographer® training courses have set the standard for thermographer training. Students who successfully complete our Level I, II, or III training courses are issued a diploma that does not expire. If you’re a thermographer who has trained elsewhere and have a certification that is about to expire, contact us to find out how you may matriculate directly to one of our courses and earn a diploma that is good for life.
Thermographer certification is one of the many topics covered in all Infraspection Institute Certified Infrared Thermographer® training courses. For more information or to register for a course, visit www.infraspection.com or call us at 609-239-4788.
Monochrome or Multi-Color?
Tip written by: Infraspection Institute
With most thermal imagers capable of displaying images in monochrome or multicolor, many new thermographers ask which color palette is the best choice for effective imaging. The answer will depend on a number of factors including application, delta T associated with the exception, and personal preference.
Because it is usually less confusing than multicolor palettes, grayscale may be better suited for some applications. Additionally, applications that have a large delta T associated with exceptions or where target recognition is important may be better suited for grayscale imaging. Such applications include electrical distribution systems, building envelopes inspected from the interior of the structure, and low slope roof inspections.
Multicolor palettes offer an advantage when imaging targets having a small delta T associated with exceptions or when imaging targets with several discrete temperature zones. Typical applications include mechanical systems, refractory systems, building envelopes inspected from the exterior, and medical/veterinary applications.
For hardcopy reports, printing monochrome images can result in lower cost than multicolor reports. Lastly, the choice to use monochrome or multicolor is largely a matter of personal preference. Thermographers should always use a palette which best represents the observed thermal patterns and provides data that are easily understood.

Selecting an IR Training Firm
Tip written by: Infraspection Institute
As thermography has gained in popularity, the demand for training services has also increased. Since operator training can have a profound effect on the success of an infrared program, obtaining quality training is of paramount importance.
At present, there are several firms that offer infrared training and certification. While nearly all infrared training firms refer to their training courses by level (1, 2, or 3), there are no standards which dictate the content of any offered course. As a result, training courses can vary widely between firms.
When choosing an infrared training firm, be certain to:
- Examine course curriculum to ensure that it meets one’s needs
- Ensure that course will be germane to all infrared imagers, regardless of age
- Ascertain if Certification is included with course, its expiration date, and renewal fees
- Determine number of years training firm has been in business – not the cumulative total of staff years
- Insist that instructors be practicing thermographers with documentable field experience in their area of instruction
Lastly, beware of claims that training is “vendor neutral”. It is impossible for training firms to sell infrared equipment or train for equipment manufacturers without being biased. Firms who train for manufacturers work for manufacturers and cannot provide the unbiased information students deserve. Simply put, no man can serve two masters.
Infraspection Institute has been providing infrared training and certification for infrared thermographers since 1980. Our Level I, II, and III Certified Infrared Thermographer® training courses meet the training requirements for NDT personnel in accordance with the ASNT document, SNT-TC-1A. All courses are taught by practicing, expert Level III thermographers whose field experience is unsurpassed anywhere in the world.

Spring is the Time for Infrared Roof Inspections
Tip written by: Infraspection Institute
With the onset of warmer weather, the harshness of winter is but a fading memory for most. Left undetected, the damage caused by winter’s fury is a reality that can lead to premature roof failure. Fortunately, an infrared inspection of your roof can detect evidence of problems before they get out of hand.
Performed under the proper conditions with the right equipment, an infrared inspection can detect evidence of latent moisture within the roofing system often before leaks become evident in the building.
The best candidates for infrared inspection are flat or low slope roofs where the insulation is located between the roof deck and the membrane and is in direct contact with the underside of the membrane. Applicable constructions are roofs with either smooth or gravel-surfaced, built-up or single-ply membranes. If gravel is present, it should be less than ½” in diameter and less than 1” thick.
For smooth-surfaced roofs, a short wave (2-5.6 µ) imager will provide more accurate results especially if the roof is painted with a reflective coating. All infrared data should be verified by a qualified roofing professional via core sampling or invasive moisture meter readings.
Infrared inspection of flat roofs and proper equipment selection are two of the many topics covered in the Infraspection Institute Level I Certified Infrared Thermographer® training course.

IR Inspections of Photovoltaic Systems
Tip written by: Infraspection Institute
With interest in renewable energy at an all-time high, photovoltaic systems have become a common sight worldwide. Infrared inspections can be used for quality assurance inspections of new installations or to monitor the performance of existing ones.
Photovoltaics is a method of converting solar energy into electricity. A photovoltaic system uses an array of several solar panels each of which is comprised of several solar cells. When exposed to sunlight, the solar cells produce direct current electricity. This DC power can then be converted to AC power for local use or to supply a power grid.
Defective cells or wiring within solar panels can cause hotspots that compromise the power output of the panel. Such hotspots are readily detected with a thermal imager while the panel is exposed to sunlight. Performed from either the topside or underside of panels, infrared inspections provide the most cost effective method for detecting defects within installed panels.
When performing an infrared inspection of an installed PV system, keep the following in mind:
- Determine best vantage point for the IR inspection
- Inspections should be performed on a sunny day when winds are calm
- Qualitatively inspect panels looking for inexplicable hot or cold spots
- Be sure to include the electrical conductors and distribution equipment that connect solar panels to the electrical system
Lastly, make certain to observe all safety precautions during the infrared inspection especially when working from an aircraft or an elevated vantage point. Personnel should also take care to avoid electrical hazards when working near exposed, energized electrical conductors.
Infrared inspections of photovoltaic panels is one of the many topics covered in the Level I Infraspection Institute Certified Infrared Thermographer® training course.

Calculating Field of View
Have you ever wondered what the size of your imager’s field of view is at a given distance? If you know the visual field of view specifications for a thermal imager, it is possible to calculate the size of your imager’s viewing area for any given distance using a scientific calculator. The formula for this calculation is:
{(tangent 1/2 viewing angle) x distance} x 2
To apply the above formula, follow these steps:
1. Determine your imager’s Field of View (in degrees) from the manufacturer’s specs.
2. Divide the value from Step 1 by 2
3. Use scientific calculator to determine tangent of number obtained in Step 2
4. Multiply number in Step 3 by distance from imager lens to object.
5. Multiply number obtained in Step 4 by 2. This will be the width of the imager’s field of view at the specified distance.
Example: Calculate field of view for 16° lens at 25’.
(tan 8° x 25’) x 2 =
(0.140541 x 25’) x 2 =
(3.513525’) x 2 = ˜ 7.0’
If your imager specifies different Field of View values for horizontal and vertical, it will be necessary to calculate each value separately. Calculated values should be used for estimation purposes as actual values may vary slightly.
Imager operation is one of the many topics covered in all Infraspection Level I and Level II training courses. For more information on our Distance Learning Program or our open enrollment classes, visit us online at Infraspection.com or call us at 609-239-4788.
Watch Your Step
“Watch Your Step” is a safety slogan we’ve all seen countless times. All too frequently, thermographers suffer injuries when engrossed in an inspection or disoriented by the display monitor of an infrared imager.
Thermography is a visual inspection technique that requires a thermographer to pay close attention to an imager’s monitor screen. Due to their construction, some portable thermal imagers can present safety hazards by partially obstructing a thermographer’s vision. Other thermal imagers may cause a thermographer to loose his/her balance due to the different perspective of the images they display.
In addition to hazards presented by imaging equipment, thermographers engrossed in an inspection can easily lose touch with their physical surroundings. To help prevent accidents, keep the following in mind:
- Always maintain adequate situational awareness of your surroundings
- Prior to imaging, survey the worksite for any tripping or fall hazards
- Be sure of your footing and overhead hazards at all times
- Stay with your qualified assistant at all times
Lastly, be extra careful when working in low light conditions. Watching a monitor screen in low light can impair your night vision for up to several minutes after you have viewed the screen. Taking the time to watch your step when imaging can help to prevent personal injury and avoid damage to your equipment or a client’s facility.
Thermographer safety is one of the many topics covered in the Infraspection Institute Level I Certified Infrared Thermographer® training course. For more information on class locations or our Distance Learning program, visit www.infraspection.com or call 609-239-4788.
