Recently, the National Standard Parts Product Quality Supervision and Inspection Center further strengthened the standardized management of experimental tooling. The "Fastener Product Test Tooling Atlas" edited by the Standard Parts Performance Room and the "Fastener Product Test Core Bar Atlas" have been compiled. And bound into a book. The "Fastener Product Test Tooling Atlas" and "Fastener Product Test Mandrel Atlas" are used to guide the technical catalogue of fastener test kits and tooling. The catalogue is in accordance with ISO, HB, GJB, ASTM and other standards on the requirements of test fixtures, standardize the tensile properties of external thread fasteners, internal thread fasteners, rivet products, nail products, self-locking fasteners , fatigue performance, shear resistance, riveting performance test, structure, size, material, processing, heat, table processing status and acceptance technical requirements of fixtures for torque test.
There are many types and specifications of fasteners, and the performances are different. The corresponding method standards are different for the inspection tool fixtures of various product parameters. The performance room organization testers organize, summarize and summarize the various method standards. The requirements of the test standard were drawn into 88 sets of tooling drawings to support the fastener mechanical performance test. The implementation of the "fastener product test tooling atlas" and the "fastener product test mandrel chart" is conducive to the reliability and accuracy of the test data, can ensure the repeatability and reproducibility of the test results, and is also conducive to work efficiency. Improve and standardize the implementation of test standards.
