ASTM C1016-94a

Standard Test Method for Determination of Water Absorption of Sealant Backing (Joint Filler) Material

SCOPE
1.1 This test method covers a laboratory procedure for determining the water absorption characteristics of sealant backing and joint filler materials, hereinafter referred to as backing.
1.2 The values stated in SI units are to be regarded as the standard. The inch-pound units in parentheses are for information only.
1.3 The committee with jurisdiction over this standard is not aware of any comparable standards published by other ASTM committees or other organizations.
1.4 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.
