BS ISO 24068-1:2021 PDF Download

BS ISO 24068-1:2021 is a standard that outlines a method for determining the degree of cure of sealants used in building and civil engineering applications. The degree of cure refers to how thoroughly the sealant has cured and is an indicator of its performance and durability. The standard specifically focuses on the build-up of tensile properties in dumbbell-shaped specimens during the curing process.

The standard is applicable to both one-component and multi-component sealants. One-component sealants are pre-mixed and ready to use, while multi-component sealants require the mixing of different components before application. The method described in the standard involves subjecting the dumbbell-shaped specimens to specific curing conditions and monitoring the changes in their tensile properties over time.

By evaluating the build-up of tensile properties, such as strength and elongation, the degree of cure of the sealant can be determined. This information is crucial for assessing the quality and performance of sealants in building and civil engineering applications. The standard provides clear guidelines and procedures for conducting the test and interpreting the results accurately.
