Introduction
This document is a Geometric Product Specification (GPS) standard and is considered a universal standard for GPS (see ISO 14638). In general GPS matrix
, it affects the size and distance under standard chain links. The GPS master plan given in GB/T 20308 provides the
General principles of GPS systems.
The basic rules for GPS given in ISO 8015 apply to this document, while the default rules given in ISO 14253-1 apply to applications based on
This document establishes specifications unless otherwise stated.
For detailed information on the relationship of the standard to other standards and the GPS matrix model, see Appendix D.
