Note 1:the actual specifications (nominal breaking strength)between the table adjacent specification,according to the linear interpolation method to calculate the corresponding evaluation index
beyond this range,the assessment index is negotiated by the parties.
Note 2: Sixth as measured by the specimen when difficult to peel or not to the specified peel strength base material or membrane rupture,deemed to be in compliance with the requirements.
Note 3:eighth standard value according to the design or agreement.
Note 4:the actual fracture strength less than the standard strength,standard strength corresponding elongation is not as consistent with the judgment.

Application:

widely used in Dam Tunnel,traffic,road,airport,row ,In many areas of water,housing,environmental protection,the main seepage prevention in engineering,Protection,reinforcement and so on.
