A few new resources
This book was released last month.
Zhang, Z.M., Tsai, B.K., and Machin, G., Radiometric Temperature Measurements, Elsevier Academic Press (2009).
Elsevier has a page with a summary of the contents:
http://www.elsevier.com/wps/find/bookdescription.cws_home/720497/description#description
Peter Saunders of MSL in New Zealand has a book availible from SPIE, Radiation Thermometry: Fundamentals and Applications in the Petrochemical Industry.
http://spie.org/x648.html?product_id=741687
MSL also has a new technical guide, "MSL Technical Guide 22, Calibration of Low-Temperature Infrared Thermometers".
http://msl.irl.cri.nz/sites/all/files/training-manuals/TG22-July-2009.pdf
Then there is a standard from BIPM WG5 on uncertainty budgets for radiation thermometer calibration, "CCT-WG5 on Radiation Thermometry, Uncertainty Budgets for Calibration of Radiation Thermometers below the Silver Point"

ASTM Meeting in Atlanta
WK21204 - Standard Guide for the Selection and Use of Wideband, Low-temperature Infrared Thermometers
This work item was completed and put up for ballot in September. There was one negative. The reason for the negative will be corrected. Then the work item will be balloted to the subcommittee prior to December 15. This way we will be ready to ballot to the main committee in time for our meeting in May.
E 1256 – 95: Standard Test Method for Radiation Thermometers (Single Waveband Type)
The figures have been updated in this standard. They will be put to ballot shortly.
A second item that will be taken care of is standardizing terminology in this standard with the terminology in IEC standards. Work on this will begin mid-February.
Proposed Work Item - Calibration of Wide-band, Low Temperature Infrared Thermometers
This work item will be submitted at the beginning of January. It will use parts of a BIPM standard and part of a technical guide for the uncertainty portion of this standard.

WK21204 Back from Ballot
There was one abstention with comment that will be discussed at length at the November subcommittee meeting in Atlanta. The rest of the comments will be part of the discussion as well.

Updating E1256
Do you use E1256?
What parts of E1256 do you use?
What should be added to E1256?
What should be taken away from E1256?
What should be changed in E1256?Please provide feedback before October 15, 2009. We should strive to keep this standard up-to-date and usable for users of radiation thermometers.
WK21204 Goes to Subcommittee Ballot
Tuesday, August 25, 2009
E20.02 Progress through 8/25/09
A draft has been sent out to six committee members for review. Feedback is due by 9/3/09. At that point it will be decided if the item is ready for ballot.
Friday, June 26, 2009
E20.02 Progress through 6/26/09
To this date 90% of the work item has been put into the ASTM standards template. It should be ready for its first review by the task group around 7/2.
Thursday, May 21, 2009
E20.02 Progress through 5/21
WK21204 - Standard Guide for the Selection and Use of Wide-band, Low Temperature Infrared Thermometers
The rough draft for this guide is complete. The following steps will take place between now and the next subcommittee meeting in November.
- The current text will be put into ‘standards form’ (June 09)
- Technical review (July 09)
- Editorial review (July 09)
- Send out for ballot (September 09)
The date of September 09 to send out for ballot is a stretch goal. It will only take place if a significant amount of editing does not need to take place after the reviews.
Calibration of Wide-band, Low Temperature Infrared Thermometers
This will be a work item that we will start on in November.
E 1256 – 95: Standard Test Method for Radiation Thermometers (Single Waveband Type)
This standard does not come up to be reapproved until 2012. However, we need to review it to see if we can make some changes. I will be discussing this with Ray Peacock in the future.
Collaboration Areas
ASTM has started collaboration areas for current work items. I have started one for WK21204. If you are interested in collaborating in the development of this standard, please contact me.
Next Meeting
The next meeting will be on Monday Nov. 9th, 2009 or Tuesday Nov. 10th, 2009 in Atlanta, Georgia.

E20.02 Progress through 3/27/09
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.

Welcome to the E20.02 Blog
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.
