This standard extends the information contained in ASME Y14.5M-1994 (which is NOT a gaging standard). This is for all those persons with an interest in learning the new rules, regulations and preferred ASME and ANSI practices on the design, dimensioning and tolerancing of GO gages, NOGO gages, Functional Gages (to verify geometric tolerances) and Fixtures (to stabilize parts for manufacturing and inspection).

This Standard presents the design practices for dimensioning and tolerancing of gages and fixtures used for the verification of maximum material condition (MMC) size envelopes and virtual condition boundaries generated by geometric tolerances controlled at maximum material condition. Examples of gages used to inspect workpieces using regardless of feature size (RFS) are shown in Appendix C. These practices focus on the design of receiver-type gages, which collect attribute data when used or the verification of workpieces dimensioned and toleranced in accordance with ASME Y14.5M-1994.
