This standard is based on the original national standard GB8386-1987 pin-core door chain (this standard was converted into standard number QB/T3833-1909 by the State Light Industry Bureau [1999112 document], and adopts the test method of ITSA1510-1995 "3. This standard has the following major technical differences from B/838-99: because it does not use anti-climbing safety door chains, the product classification is based on the lock, the content of the solidity and time, appearance and multiple view requirements are combined, and the product performance and actual use are analyzed. Two major changes: increase the number of feasible test cases To promote product quality according to high requirements and test methods, the inspection rules are supplemented with specific inspection rules, and the product content is added. This standard is promoted by the National Light Industry Bureau. This international standard is issued by the National Hardware Standardization Administration. The responsible drafting unit of this standard: Shanghai Shang Lock Product Quality Supervision and Inspection Station. Guangdong Zhongshan Huaduo Lock Co., Ltd., Jiangsu Huzhou Lock Co., Ltd., this standard is based on the original industry standard QBT3838-1999 issued by the State Light Industry Bureau [Mortar Door Lock Wide Allow,
