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

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.

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

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.

E20.02 Progress through 5/21

We held our E20.02 meeting in Vancouver this past Monday. I lead the meeting via Web-Ex from American Fork, Utah. It went rather well. Here is an update on our subcommittee's progress.

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.
