Description

This International Standard specifies the most important dimensional, functional and quality characteristics of micrometer callipers for external measurement. Information concerning values for the error of measurement at any point in the measuring range and recommendations for using the instruments and testing their accuracy are given in annexes.

Scope

This International Standard applies to micrometers equipped with a screw having a lead of 0,5 or 1 mm, having a maximum range of 25 mm covering capacities up to 500 mm, and having non-removable anvils with flat measuring faces.

Note — This International Standard does not apply to digital reading micrometers but may be used tor indicating desirable requirements for such micrometers where appropriate.
