Standard Test Method for Staining and Color Change of Single- or Multicomponent Joint Sealants

Importancia y uso:

4.1 Staining of a building is an aesthetically undesirable occurrence. This test method evaluates the likelihood of a sealant causing early stain on a porous substrate due to certain chemical exudations from the sealant.

4.1.1 This test method may not predict staining caused by such factors as residue run-down or dirt pick-up by a sealant exudate.

4.2 This test method is useful to predict potential color changes in the sealant itself after weathering.

4.3 This test method measures color change in a sealant and staining of substrate by the sealant under conditions of artificial weathering. See also Test Method D2203, which measures staining by a sealant due to gross exudations from the sealant; it does not subject the sealant to artificial weathering.
