ISO 13638:2021 PDF Download

ISO 13638:2021 is a standard. This standard specifies a method for evaluating the ability of sealants to resist prolonged exposure to water under real-world conditions. The standard focuses on assessing the effects of water immersion on the sealants' ability to meet their essential functions, primarily to withstand joint movements.

The method described in the standard involves subjecting the sealant samples to different durations of water immersion. By doing so, the standard aims to determine the sealants' ability to maintain their performance and integrity over time, even when repeatedly exposed to water. This assessment is crucial in ensuring that the sealants used in building and civil engineering applications can withstand moisture, preventing water infiltration and potential damage to the structures.
