). A relative elongation of 15% is considered to be broken. 2
4.3 Forged clamps shall be tested according to the requirements of Grade II forgings specified in JB4385 and the hardness test ratio of Grade II forgings. Magnetic particle inspection, qualified according to JB3965 Grade III,
4.4 After each batch of clips is manufactured, refer to the methods and procedures specified in GB2828 and carry out sampling tensile test according to the values ​​in Table 5, Table 5
Batch basket, piece
Tensile test sampling number
1%, and not less than 5 pieces
0.5%, and not less than 10 pieces
Allowed number of unqualified
1. Less than or equal to 10% of the number of samples inspected is qualified; 2. For those greater than 10% of the number of samples inspected and less than or equal to 20%. 1-2 rechecks and random inspections can be conducted. The number of rechecks and random inspections is the same as the sum of the number of random inspections previously conducted. However, the total number of unqualified items shall be less than or equal to 10% of the total number of random inspections to be qualified.

Additional instructions:
This standard was proposed by China National Chemical Equipment Corporation and is under the jurisdiction of the National Glass Equipment Standardization Technical Committee. This standard was drafted by the Shanghai Pharmaceutical Design Institute of the State Drug Administration. The main drafters of this standard are Ye Wenbang, Li Yijun and Hua Qiuyuan. From the date of implementation of this standard, the former Ministry of Chemical Industry's standard HG5-269-79 "Glass Equipment Clips" shall be invalidated. This standard A-type clip is based on the German national standard DIN28152-1979 "Clips for pond glass containers, dimensions and configurations".
