Note 1: The actual specification (nominal breaking strength) is between the adjacent specifications in the table, and the corresponding assessment index is calculated according to the linear interpolation method.
Note 2: In item 6, if the sample is difficult to peel off or does not reach the specified peel strength, the base material or film material shall be deemed to meet the requirements.
Note 3: The standard value of Item 8 is based on design or agreement.
Note 4: When the actual breaking strength is lower than the standard strength, the elongation corresponding to the standard strength shall not be judged for conformity.
