ISO 11617:2022 PDF Download

ISO 11617:2022 is a standard that outlines the procedures for testing the changes in cohesion and appearance of elastic weatherproofing sealants used in building and civil engineering. This standard focuses on determining the effects of artificial weathering and mechanical cycling on sealants that have been statically cured.

The purpose of this standard is to provide a laboratory-based exposure method to assess the performance of sealants under conditions that simulate real-world environmental and mechanical stresses. By subjecting the sealants to artificial weathering, which includes exposure to various levels of temperature, humidity, ultraviolet radiation, and other weathering factors, the standard aims to evaluate the changes in cohesion and appearance of the sealants.

The test method described in ISO 11617:2022 involves preparing specimens of the sealants and subjecting them to mechanical cycling, which simulates the movement and stress experienced by sealants in real-life applications. After the mechanical cycling, the specimens are then exposed to the artificial weathering conditions.

The standard provides guidelines on the specific test parameters, such as the duration of exposure, the number of cycles, and the specific weathering and cycling conditions. The changes in cohesion and appearance of the sealants are then evaluated and reported as per the standard's requirements.
