Full Description
Includes errata.This Standard is intended to establish uniform practices for the measurement of thread measuring wires. The standard includes methods for the direct measurement of both master and working wires, and methods for the comparsion measurement of working wires. The standard includes requirements for geometric qualities of thread measuring wires, the important characteristics of the comparison equipment, environmental conditions, and the means to ensure that measurements are made with an acceptable uncertainty level. Wires covered by the standard include inch series 60-deg, 20-deg Acme, 7/45-deg Buttress, and metric 60-deg threads.
