This specification describes preformed tape sealants for use in glazing applications. These materials are generally used to serve as components of glazing systems. They are intended to serve as a water and air barrier. The preformed tape sealant shall be composed of appropriate raw materials conformed to the requirements specified. The preformed tape sealant shall be of uniform dimensions and consistency. When properly applied, this material shall form a seal to prevent air and water from entering the system. Different test methods shall be performed in order to determine the following properties: low temperature flexibility, weight loss, vehicle migration, backing removal, yield strength, compression or recovery, water absorption, and flow.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
Significance and Use
6.1 This specification describes only preformed tape sealants for glazing applications. Their use is specific under glazing systems to serve as a water and air barrier. The test methods chosen are to determine their efficiency in this use. This specification does not describe all required properties of the preformed tape sealants. It should be recognized by the purchaser and design professional that not all preformed tape sealants meeting this specification are suitable for all applications. In some instances, additional requirements will be agreed to by the supplier and user.
1.1 This specification describes preformed tape sealants for use in glazing applications. These materials are generally used to serve as components of glazing systems. They are intended to serve as a water and air barrier.
1.2 This specification is not intended for preformed foam tape sealants.
1.3 The values stated in SI units are to be regarded as the standard. The values in parentheses are provided for information purposes only.
1.4 The subcommittee with jurisdiction is not aware of any similar ISO standard.
1.5 The following precautionary statement pertains only to the test method section of this specification. 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.
