The intent of these tests are to provide a means for the participant to determine the appropriateness and effectiveness of their practices, training, and measurement uncertainty relating to calibration of length standards.

The proficiency test kits include English gage blocks and Metric gage blocks in various sizes and micrometer standards.  Choose which kit best suits the capabilities of your laboratory.

 

This test consists of a set of 9 English gage blocks 0.0625 to 2.00 inch

The intent of this ILC/PT is to provide a means for the participant to determine the appropriateness and effectiveness of participant practices, training, and measurement uncertainty relating to calibration of steel gage blocks.

Reference values are obtained by mechanical comparison. This program is suitable for participants who measure gage blocks by mechanical comparison, whose uncertainties are not significantly smaller than the typical reference uncertainties, and who calculate their uncertainties per the method of the ISO GUM.
