适用范围：This part of ISO 16938 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 likelihoodof a sealant causing an early stain on a porous substrate due to exudation of materials from the sealant. Theoutcome of the test is specific to the tested sealant and tested substrate and cannot be extrapolated to othersealant formulations or other porous substrates. During this accelerated test, if the sealant does not stain ordiscolour the substrates, it does not mean that the tested sealant will not stain or discolour the tested poroussubstrate over a longer time period. Experience in various countries with similar test methods has shown thatthe compression of test specimens further accelerates the occurrence of staining.
