ISO 4784:2022 PDF Download

ISO 4784:2022 standard describes a methodology for assessing the surface cure of various types of sealants used in the construction and civil engineering industries. This standard outlines a procedure that can be utilized for both single and multi-component sealants.

The primary objective of this standard is to provide a consistent and reliable method of measuring the surface cure time of sealants. Surface curing refers to the point at which a sealant has reached sufficient strength on its outer layer, allowing it to be handled or subjected to further construction activities without being damaged or losing its adhesive properties.

ISO 4784:2022 specifies the testing conditions and equipment required to carry out the determination of surface cure time accurately. This standard focuses on evaluating factors like temperature, humidity, and exposure time, which can influence the curing process.

By providing standardized guidelines, ISO 4784:2022 ensures that the determination of surface cure time is conducted in a consistent and reproducible manner. Adhering to these protocols enables companies in the building and civil engineering sectors to assess sealant performance and make informed decisions regarding the timing of subsequent construction activities or project completion.
