Infraspection Institute Releases New Standards for Infrared Thermography

Burlington, NJ, USA — February 13, 2008 — Infraspection Institute has announced the release of eight new standards for infrared thermography. Four of the new standards cover thermal imaging applications and four are dedicated to equipment operation and temperature measurement.



Jim Seffrin, Director of Infraspection Institute, states, “We are very excited about the release of our new standards. One of the most common requests among thermographers is to have a uniform set of industry standards. In fact, standards were high on the wish list of several attendees at our recent IR/INFO conference.”

Recognizing the need for standardized procedures, Infraspection Institute began publishing guidelines for thermography in 1993.

Since their initial publication, Infraspection Institute guidelines have been adopted by hundreds of companies worldwide and incorporated into documents published by recognized standards organizations such as the American Society for Testing and Materials (ASTM).

Beginning in 2007, Infraspection Institute guidelines were updated and renamed as standards to reflect their industry-wide acceptance and the best practices they embody.

Eight comprehensive standards are now available from Infraspection Institute. These documents cover equipment operation, temperature measurement, and specific thermographic applications. Current titles include:

Standard for Infrared Inspection of Electrical Systems & Rotating Equipment

Standard for Infrared Inspection of Insulated Roofs

Standard for Infrared Inspection of Building Envelopes

Standard for Infrared Inspections to Detect Pests and Pest Related Damage

Standard for Measuring and Compensating for Emittance Using Infrared Imaging Radiometers

Standard for Measuring and Compensating for Reflected Temperature Using Infrared Imaging Radiometers

Standard for Measuring and Compensating for Transmittance of an Attenuating Medium Using Infrared Imaging Radiometers

Standard for Measuring Distance/Target Size Values for Infrared Imaging Radiometers

To assure accurate noncontact infrared temperature measurement (on the Raytek Corporation website)

A brief discussion of five key factors that have to be taken into account when planning use of an IR thermometer to make a noncontact temperature measurement.

These then are expanded upon in other Raytek web pages as part of the their website education area.

The Five Key Elements, you ask?

According to Raytek they are:

* Distance to Target (Spot) Ratio
* Field of View
* Environmental Conditions
* Ambient Temperatures
* Emissivity

Editors Note: We think that’s an excellent start, but would add that response time and traceable calibration as two equally important factors, if one is planning to make truly serious temperature measurements, such as is often encountered when using the measurement in controlling a process that has time-variable properties.

The December ITC Inframation Newsletter (Vol. 8 Issue 12) has a thermal imaging applications story from experienced thermographer, Ronald Ruiz of the Reliability and Failure Analysis Group at the Jet Propulsion Laboratory, Pasadena, California ..”showing how he uses IR to inspect electronics that go literally ‘out of this world’”.

He’s been detecting  flaws in ASIC integrated microcircuits in regions as small as 15 micrometers in diameter!

The ITC Inframation Newsletter has been around for eight years now and is available by email on a free subscription basis , or you can view the archive on the ITC Website for the first few years.

To access the entire archive one needs to register on the site, but the information is still free!

A free, downloadable, PDF Format-328 KB, applications story in English is available on the DIAS Infrared website. It is entitled “High speed infrared camera for contactless temperature measurement on rotating tires” and is authored by by Helmut Budzier, Dresden University of Technology, Institute for Solid-State Electronics & DIAS Infrared GmbH, Manfred Zimmerhackl, DIAS Infrared GmbH, Volker Krause, Dresden University of Technology, Institute for Solid-State Electronics, and Günter Hoven, CMV Hoven GmbH in Germany.

Part of the paper’s conclusion’s are:

“…… it is possible to detect smallest temperature changes and to make an automatic online processing control even at 450 km/h. Figure 2 shows an example of a tire testing system. Figure 6 shows a tire profile at 280 km/h.”

Thermometrics Corporation has an extensive webpage describing the various types of temperature sensors used in measuring food temperatures in both professional settings and at home.

They have an additional webpage that reviews the reasons why knowing food temperature and time at temperature is important.

That page echoes the USFDA webpages on the subject that are linked in the TempSensor.net Directories along with others.

As the Holidays approach, more warnings will be posted about food temperature and the proper cooking temperatures and safe time for cooked foods to be out in the open without refrigeration. After all, bacteria have to live, too!

Raytek Corporation, one of the major manufacturers of industrial, online noncontact infrared thermometers and thermographic sensors (line scanners) has a summary web webpage dedicated to special groups of applications.

Among them is this special page covering the following building and construction materials processing uses:

Cement Processing - Infrared Monitoring of Kiln Shells Extends Refractory Life
using the Raytek Model CS200 Thermal Imaging System, a fully integrated solution that monitors rotary kilns to detect hot spots and avoid costly damage and unscheduled downtime.

Wall Board Mixer Slurry Rise/Set Temperature Monitoring System
Describing how the Raytek Model TRS100 Mixer-slurry Rise/Set Monitoring System replaces traditional manual thermocouple sampling and testing methods.

Thermal Imaging and Profiling System for Wallboard Applications
Raytek Model TIP450 Thermal Imaging System measures wallboard moisture content, identifies board defects, providing a real-time board detailed image of each board set as it leaves the dryer.

Construction Glass Manufacturing and Tempering
The Raytek Model GS100 Thermal Imaging System is an automated temperature measurement system for glass bending, forming, annealing, and tempering processes, and the use of their Model GS110 System for Low Emissivity (Low-E) Glass

The October 2007 issue of ‘Through the Lens’ an e-newsletter dedicated to technological innovations and applications advances in Infrared Imaging, the regular ‘Applications Corner’ feature investigates how researchers in the automotive industry are using thermographic techniques to study a wide range of applications including engine cooling, air conditioning, heat dissipation of electronic components, stress and fatigue in chassis components as well as brake and tyre performance.

In this issue of also, the feature article describes advanced techniques for measuring the temperature or radiance of thermally dynamic events.
