Integrity Solutions Group has prepared various analyses and presentations to establish an integrated means to assure technically correct, integrated, and cost-effective Measurement Uncertainty Estimates. A useful tool is a computerized calculation program that:
- helps reinforce knowledge of the subject,
- is rich in examples,
- is generally very faithful to the methodology,
- does not advocate the approach of one "Guru" over another "Guru",
- has been used by many,
- has had various improvements with time,
- remains current,
- is simple to validate,
- and, is free.
The only program known to meet this criteria is the "Uncertainty Calculator" by Chris Grachanen. This program can be downloaded from ftp://ftp.fasor.com/pub/iso25/uncertainty/un_cal/ or http://metrologyforum.tm.agilent.com or http://www.ecalibration.com/ecalibration/17025d.htm.
Assessments at various labs indicate many Measurement Uncertainty problems (to the extent that some assessments were aborted) exist at the time of assessment. Organizations that have adopted this software and the integrated approaches of Integrity Solutions Group, available as described below, have been successful.
