Precision Measurement Technical Bulletins and Guides

Study: Coefficients of Thermal Expansion Thermal Expansion in dimensional calibration is a significant factor to the values we report on traceable certificates. Thermal expansion is dependent on the composition of the material we measure and the standards we use for comparison. In addition, the time allowed for the device under…

Wondering how big (or small) a micron actually is? Check out the following infographic. The answer may surprise you. 

Measurement of small radius and radius with short arc length or included angle present a challenge to metrologist regardless of the device used to gather data points. The following data illustrates the effects of form error and/or measurement error and reduction of arc length. 1. Points A1 (X0,Y0.5), B1 (X0.01913,Y0.04619) and…

Below are methods used to calibrate gage blocks within all J.A. King network locations offering gage block calibration services. Primary Method Per national standards, the length of the gauge block is defined as the distance between a flat surface wrung to one end of the block, and a gauging point…
