What is ISO 16938 ‑ 1 – Buildings and civil engineering works about?
ISO 16938 is an international standard on building applications that discusses the determination of the staining of porous substrates by sealants used in joints for buildings and civil engineering works.
ISO 16938 ‑ 1 is the first part of ISO 16938 which 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 spec...
