See Chinese contents: GB/T 13477.15-2017 GB/T 13477.15-2017: Test method for building sealants -- Part 15: Determination of adhesion/cohesion properties after exposure to heat and artificial light through glass and to water
This part of GB/T 13477 specifies the method for determining the adhesion properties of sealing materials after cyclic exposure to heat, water, and artificial light through glass. This part is applicable to the determination of changes in the adhesion properties of sealing materials after cyclic exposure to heat, artificial light, and water. NOTE: The cyclic exposure test of the specimen to heat, light source and water is similar to the natural aging conditions of sealing materials in actual use. Compared with the actual use conditions, the acceleration factors are unknown and cannot be used to evaluate the durability of sealing materials. However, a minimum performance guarantee for glazing can be obtained.
