Note 1: The specifications are based on the breaking strength, and the actual specifications are between the adjacent specifications in the table, and the corresponding assessment indicators are calculated according to the linear interpolation method.
Note 2: When the actual breaking strength is lower than the standard strength, the elongation corresponding to the standard strength shall not be judged for conformity.
Note 3: The standard value of Item 8-Item 9 is based on the design or agreement.
