Abstract

Gauge blocks are the most popular and widespread material length standards used throughout industry. Although they are relatively robust, obtaining the best accuracy from gauge blocks requires proper handling. Written for those new to using gauge blocks, or for more experienced users who would like to refresh their knowledge, this guide outlines some of the best practices for handling, inspecting, cleaning and storing gauge blocks. Readers will also learn how to determine which gauge blocks to use, how to wring them and some basics of gauge block calibration.
