BS ISO 4784:2022 PDF Download

BS ISO 4784:2022 is a standard that specifically focuses on the determination of surface cure time for sealants used in building and civil engineering. The standard provides technical terms and specifications for sealants, aiming to improve the understanding and quality of these products.

The standard outlines a method for assessing the surface cure of both one-component and multi-component sealants. It covers aspects such as the apparatus and materials needed for the test, preparation of test specimens, and the actual test procedures. Additionally, guidance is provided on how to calculate and express the results of the surface cure time determination.

This standard is relevant and useful for various stakeholders in the construction industry, including builders, architects, construction engineers, sealant manufacturers, government and private entities, regulatory bodies, structural engineers, infrastructure contractors, and project managers. By following the guidelines set by ISO 4784, these stakeholders can ensure the proper evaluation of sealant surface cure time, leading to the construction of durable and long-lasting structures.
