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.

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.
