GB/T 16656.32-1999

This standard specifies the requirements for testing laboratories and clients involved in conformance testing of product data exchange implementations, ensuring consistent and reliable evaluation of STEP (Standard for the Exchange of Product Model Data) applications. It is applied in industrial automation and manufacturing sectors where organizations need to verify that their software systems correctly implement product data exchange standards, particularly for CAD/CAM and product lifecycle management interoperability. The standard defines the responsibilities, procedures, and documentation needed for both testing facilities and their clients to conduct valid conformance assessments.
