WK21204 - Standard Guide for the Selection and Use of Wide-band, Low Temperature Infrared Thermometers

A rough draft is 80% complete. Thanks to Don H and Terry C for their help with Section 11.

There are portions of a few standards from the E07 Committee that are applicable for this work.

The plan is to use much of the wording in these standards for the following sections.

• 6.1. Methods of Determining Emissivity
• 7.1. Testing for Background Radiation
• 11.1. Thin Films

The appendices must be completed before the rough draft is completed. The proposed appendices are:

• Appendix 1. Graphical Summary of Equations for IR Thermometry
• Appendix 2. Effect of Emissivity Uncertainty

Also, if anybody has some more information on atmospheric effects on the 8 – 14 μm band, please let me know. Jerry Fraser of NIST has provided me with some info.

Meeting in Vancouver

Due to the economy, I will have to lead this meeting remotely. The meeting will be on May 18 from 12:45 PM to 1:45 PM PDT (that’s 3:45 PM to 4:45 PM EDT). This meeting will take place via Web-Ex.

E20.02 Progress through 2/27/09

WK21204 - Standard Guide for the Selection and Use of Wide-band, Low Temperature Infrared Thermometers

A rough draft is 60% complete. Once completed, this will need to be put into an ASTM writing style. The following sections still need to be written.
Referenced Documents
Terminology
Physical Considerations
Special Applications of IR Thermometry
-Measureing Metal Surfaces
-Atmospheric Attenuation
Keywords
Appendix 1. Graphical Summary of Equations for IR Thermometry
Appendix 2. Effect of Emissivity Uncertainty

We could still use a few ideas for Section 11. The outline for the guide currently looks like this.

1. Scope
2. Referenced Documents
3. Terminology
4. Basic Use of IR Thermometry
4.1. Basic IR Measurement
4.2. Locating a Hot or Cold Spot
5. Wideband Instruments
6. Emissivity
6.1. Methods of Determining Emissivity
6.1.a. Emissivity Tables
6.1.b. FTIR testing
6.1.c. Comparison method
6.1.d. Contact v Non-contact method
6.1.e. Blackbody method
6.2. Compensating for Emissivity
7. Background Radiation
8. Low Temperature Measurements
9. Optical Considerations
10. Physical Considerations
11. Special Applications of IR Thermometry
11.1. Measureing Metal Surfaces
11.2. Atmospheric Attenuation.
12. Keywords
Appendix 1. Graphical Summary of Equations for IR Thermometry
Appendix 2. Effect of Emissivity Uncertainty

Help Needed on Writing Sections

If you have any expertise on any of these topics, please let me know. I am looking for people willing to write anywhere from 250 to 500 workds on each of these topics. I am not looking for final copy quality but for rough draft quality.

Basic Use of IR Thermometry
Wideband Instruments
Emissive Considerations
Background Considerations
Low Temperature Measurements
Optical Considerations
Physical Considerations
Special Applications of IR Thermometry

Welcome to the E20.02 Blog

I would like to take this opportunity to welcome everybody to the ASTM Subcommittee E20.02 on Radiation Thermometry blog. I hope this medium can be use as an effective tool to communicate the activity of our subcommittee.

At our last meeting in November at St. Louis, a course of action was decided for our proposed standard, "Standard Guide for the Selection and Use of Wide-band, Low Temperature Infrared Thermometers". As progress in this work continues, this progress will be updated here.

I would like to thank Terry Halfacre for volunteering for the job of secretary for our subcommittee. Her help in this effort is much appreciated.

I would also like to thank former subcommittee chairman Ray Peacock for all the work he has done in Radiation Thermometry. His continued input will still be very valuable to us as this work goes forth.

Our next meeting will be in Vancouver, BC in May. To those who can attend, I will look forward to seeing you there. To those who cannot attend, there will be an opportunity for you to take part in this meeting via Webex.
