ASTM C510-90(1997)e1

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

SCOPE
1.1 This test method describes an accelerated laboratory procedure to determine if a sample of a joint sealant will stain the substrate when in contract with masonry, concrete, or stone (such as marble, limestone, sandstone, and granite). This test method also is intended to determine whether the sealant itself will change in color when exposed to the weather.
1.2 The values stated in SI units are to be regarded as the standard. The value given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety concerns, 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.
