- What is ISO 16938 ‑ 2 - Buildings and civil engineering works about? ISO 16938-2 discusses the determination of the straining of porous substrates by sealants used in joints for building, and civil engineering works. ISO 16938 ‑ 2 is the second part of the ISO 16938 series that specifies a method for determining the staining of porous substrates (e.g., marble, limestone, sandstone, or granite) by sealants used in building construction. The method evaluates the likelihood of a sealant causing an early stain on a porous substrate due to the exudation of materials from the sealant. The outcome of the test is specific to the tested sealant, and tested substrate, and cannot be extrapolated to other sealant formulations or other porous substrates. During this accelerated test, if the sealant does not stain or discolour the substrates, it does not mean that the tested sealant will not stain or discolour the tested porous substrate over a longer period. ...
