This standard specifies the measurement of the performance change of plastic specimen as immersed in liquid chemical reagent without being affected by external influences. This standard does not include the environmental stress cracking test (ESC) as specified in ISO 22088-2:2006, ISO 22088-3:2006, ISO 22088-4:2006. This standard only applies to the determination of the specimen the surface of which is completely immersed in liquid chemical reagents.

This Standard stipulates the basic requirements for the type and size, profile size and deviation, technical requirements, marking and packaging of thread rolling flat dies for general purpose metric screw threads. This Standard applies to thread rolling flat dies for processing general purpose metric screw threads (GB/T 192~193, GB/T 196~197). Thread rolling flat dies are divided into three precision grades: grade 1, grade 2 and grade 3. Grade 1 applies to the processing of external threads with tolerance grades 4 and 5; grade 2 applies to the processing of external threads with tolerance grades 5 and 6; grade 3 applies to the processing of external threads with tolerance grades 6 and 7.

This Part of GB/T 4802 specifies a method for determination of the resistance to pilling and surface change of textile fabrics using a modified Martindale method.
