Buildings and Civil Engineering Works: Determination of the Staining of Porous Substrates by Sealants Used in Joints - Part 1: Test with Compression
Also Known As:
ISO 16938-1:2019 standard provides a method for assessing the potential staining of porous substrates caused by sealants commonly used in the construction of buildings and civil engineering works. The aim is to evaluate whether the sealant can cause early stains on porous materials such as marble, limestone, sandstone, or granite, by releasing substances that can discolor the substrates.
The test outlined in this standard is an accelerated test that focuses on the exudation of materials from the sealant and their potential to cause staining. It is important to note that the results obtained through this test are only applicable to the specific sealant and porous substrate combination being tested. The standard cautions against generalizing the results to other sealant formulations or different porous substrates.
It is worth mentioning that a negative result from this test, where no staining or discoloration occurs, does not guarantee that the tested sealant will not cause staining or discoloration over a longer period of time. Therefore, this standard serves as a valuable tool for assessing the staining potential of sealants on porous substrates, helping to ensure the selection of sealants that minimize the risk of unwanted staining in construction projects.
