Building construction -- Determination of the staining of porous substrates by sealants used in joints -- Part 2: Test without compression
This standard was last reviewed and confirmed in 2011. Therefore this version remains current.
ISO 16938-2:2008 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 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.
