Presentation on NCSLI RP-5

For the Metrology Webinar, the morning of 8/26/09, As committee chair, I presented an NCSLI 155.1 Committee Report on Recommended Practice for Measuring and Test Equipment Specification (RP-5). The attendee’s discussed the EU standard entitled “Technical Schedule for Measuring Equipment, the AFNOR FD X 07 025 Guidelines, and how it should be addressed and referenced in RP-5. The recommendation is that AFNOR FD X 07 025 be place in a separate Appendix for reference.

The current status is:

  • We now have a complete and comprehensive initial draft (154 pages) from which to start our editorial review.
  • The comprehensive draft of RP-5 was presented at the 155.1 Committee Meeting on Monday, Jul 27, 2009 at the NCSL International Conference in San Antonio, TX.
  • Incorporate the recommended changes form the table review in San Antonio. Second editorial pass on the comprehensive draft document during September 2009
  • First pass editorial review by the entire committee (Members) starting the end of September 2009
  • Public review for editorial comments in October -November 2009
  • Final committee proof and review December 2009
  • Currently scheduled for the proper vetting of RP-5 to the NCSLI Board of Director s for their meeting of January 2010

The underlying goal is to harmonize RP-5 with NCSLI RP-1; Calibration Intervals and NCSLI RP-12; Measurement Uncertainties using the same instrument examples and data.

Public review and comment copy is expected to be available in October 2009. Contact me for an Adobe .pdf file to be sent when RP-5 is available for public comment.

Measurement Uncertainties at low RH Values

I had asked Kevin Bull (Veriteq Instruments) a question on the behavior of the Measurement Uncertainties at low RH Values like those we experience in the Phoenix-Tucson area. His excellent answer is posted in the Discussion Forum.

World Metrology Day

Happy World Metrology Day (May 20th) - A day to celibate!

Did you remember (or even know) that May 20th had been declared World Metrology Day? The dedication was made at the General Conference on Weights and Measures in 2000 to commemorate the signing of the Metre Convention on that day in 1875. This Treaty aimed to provide a formal basis for international agreement on units of measurement based on the metric system.

It seems, though, that the great day is set to pass with little notice being taken by the majority of the population who, the governors of the measurement world assert, should be celebrating the good work done by you and your peers. But from evidence garnered by trawling the world-wide web during the past week, scant attention is being given to the matter even by the national metrology institutes (NMIs)  http://www.agilent.com/metrology/news20050520.shtml

For Prof. Andrew J. Wallard, Director of BIPM,  Metrology Day insightful message see: http://www.worldmetrologyday.org/Directors_Message.html
