In order to adapt product changes and market management, to further approach or equalize international standards, to promote trade and exchange, it is necessary to revise GB 17565-1998 General Specification for Burglary-Resisting Doors. In the revised edition, new test items are added, and items and corresponding terms and definitions not applicable are deleted. According to practical product changes, being practical and realistic, partial technical parameters are revised and altered. Coming down to earth, burglary-resisting security classes are newly divided. To make inspection methods more scientific and logic, some test methods have referred to ISO 8275:1985(E), CEN/TS 13126-8: 2004 standard, which may be directly referenced and supersede some inspection items not applicable by demonstrations. 1Contents General Specification for Burglary-Resisting Doors .1 1.
