Description

This standard specification covers the basic requirements for cylindrical sealant backing for use with cold liquid-applied sealants.

Cylindrical sealant backings are classified into three types: type C, type O, and type B, composed predominantly of closed cell material, open cell material, and bi-cellular material, respectively.

Test methods for cylindrical sealant backing include water absorption, density, outgassing, compression deflection and recovery, and tensile strength. The sealant shall be clean, free of scale, foreign matter, oil, or water.

Scope

1. This specification covers the basic requirements for cylindrical sealant backing to be used with cold liquid applied sealants for use in building seals.

2. Cylindrical sealant backing serves one or more of the following functions:

Limits the amount and depth of sealant applied into a joint,
Acts as a bond breaker to allow joint movement without undue stress to the sealant,
Provides a form to assist the sealant in developing the proper shape factor, and
Acts as a barrier to the flow of sealant through the joint.

3. The committee with jurisdiction over this standard is not aware of any comparable standards published by other ASTM committees or other organizations.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

5. This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
