(Test Method)Standard Test Method for Staining from Sealants
Standard Test Method for Staining from Sealants
SCOPE
1.1 This test method covers a laboratory procedure for determining whether a sample of sealant will cause staining of the substrate when in the contact with masonry, concrete, or stone (marble, limestone, sandstone, granite, etc.).
1.2 The values stated in SI (metric) units are to be regarded as the standard. The values given in parentheses are provided for information only.
1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Note 1—Currently there is no ISO standard similar to this test method.
