E20.02 Update 4/5/10

It has been a while since I have done an update. There is quite a bit of material to cover.

WK 21204
Standard Guide for the Selection and Use of Wideband, Low Temperature Infrared Thermometers

Since the November meeting in Atlanta, this item was re-balloted in sub-committee. It received 10 affirmatives, 0 negatives and 2 abstentions. It then went to the main committee where it received 18 affirmatives, 0 negatives and 28 abstentions. We will be talking more about this at the May meeting. I would like to thank everybody for their contributions and feedback during this process. This guide will promote better IR and radiation thermometry measurement in the future.

WK 26408

This work item was to update the figures in E1256. The work was done in November. The changes made were strictly cosmetic. Upon talking to ASTM staff, it was determined that these changes did not need to be balloted. Thus, this work item is closed.

WK 26410

This work item determines what terminology in E1256 should be changed to conform to IEC 62942-1. A list of terminology will be discussed during the May meeting in St. Louis.

WK 27665

New Guide for Accuracy Verification of Wideband Infrared Thermometers
An outline and scope have been prepared for this guide. More discussion will take place during the meeting in May.

Other News

There are a set of radiation thermometry guides in Germany. They are from VDI (VDI/VDE 3511 Blatt 4). This standard consists of five guides covering various topics relating to radiation thermometry. I am currently in contact with the chair of the technical committee. I would like to determine the usefulness of this material as part of a future standard.

May Meeting

Our May meeting will be in St. Louis. It will be the first subcommittee meeting taking place from 8:15 to 9:15 AM CDT. The meeting will again be held virtually. I would encourage all to attend. The virtual meetings have worked well, and as we get more experience conducting them, they will become even better.

A few new resources

There have been quite a few developments in literature for IR and radiation thermometry. Here is a brief list.

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:

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"
http://www.bipm.org/wg/CCT/CCT-WG5/Allowed/Miscellaneous/Low_T_Uncertainty_Paper_Version_1.71.pdf

ASTM Meeting in Atlanta

We held our meeting on Monday in Atlanta. Here is an update on progress from the E20.02 subcommittee on Radiation Thermometry.

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

WK21204 went through subcommittee ballot this past month. Results were 6 affirmative, 1 negative and 6 abstention. After talking to the one negative voter, it was agreed that the negative will be withdrawn if the suggested changes are made.

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

I would like to have input on E20.02’s current standard, E1256 Standard Test Methods for Radiation Thermometers. I would like to have some feedback to the following questions.
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

The proposed guide, WK21204 - Standard Guide for the Selection and Use of Wide-band, Low-temperature Infrared Thermometers, has been sent out for subcommittee ballot. I would like to thank all who have helped to get this work item to this point. If you are a voting member, please cast your vote before October 15, 2009.

E20.02 Progress through 8/25/09

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.
