4. Limit gauges
4.1 General
A gauge can be defined as a specialized instrument that materializes a length, profile or volume, designed to verify that one or more dimensions of a part meet set limits.
There are three types of gauge:
gauges with fixed limits, usable only for the size and limits for which they were designed;
gauges with adjustable limits, which can be used, after adjusting their dimensions to the limit dimensions to be verified, over the measuring range that characterizes them;
-
Indicator gauges that can also give values for deviations from limit dimensions....
