1Type 1 dumb-bell test piece. Maximum specimen thickness according to the test standard is 3mm. 2Nominal values. 3Based on single test results. Can be used for information / reference only. 4Application temperature refers to the ambient temperature during installation and the surface temperature of the substrate (e.g. ArmaClad Arma-Chek R covering) to which the product is installed. 5For environmental conditions outside the given range, please contact Technical Services. 6Shelf life (maximum storage time) is limited to ensure that only currently manufactured products are installed on projects. This limitation is restricted solely to storage of the product and does not affect the lifetime of product after it has been installed. | ||||||||||
