For each test method, three test specimens for each substrate shall be tested. The same batch of sealant (and primer, if used) shall be used in all tests. The same substrates (material and surface finish) shall be used in all tests. Tests shall be performed on glass according to ISO 13640. kSIST FprEN 15651-2:2016

Substrates to be used in all mechanical tests concerned shall be glass according to ISO 13640. Additional substrates to be considered mortar are M1 or M2 and/or anodised aluminium. 4.3 Performance requirements 4.3.1 General Classes for elastic sealants for glazing in building construction are referred to as type G. A summary of the characteristics and classes are given in Table 2.
