Significance and Use | ||
5.1 Preformed tape sealants are tacky, deformable solids that are used under compression between two substrates in various sealing applications. These tapes are usually supplied in roll form with a release paper interlayer. When the roll is unwound and the release paper is removed from the preformed tape sealant, there should be no transfer of the preformed tape sealant to the release paper, nor any residue left on the paper. These methods will give a qualitative indication of whether or not the release paper can be removed cleanly from a preformed tape sealant after a controlled exposure period. 5.2 Alternative procedures are listed because some preformed tape sealants are normally used under field conditions where elevated temperatures can be encountered, while other preformed tape sealants are normally used under more controlled environments in “assembly line” operations. |

1. Scope | ||
1.1 These test methods cover laboratory procedures for evaluating the release characteristics of a release paper intended to be supplied in direct contact with a preformed tape sealant. 1.2 The values stated in metric (SI) units are to be regarded as the standard. The values given in parentheses are provided for information purposes only. 1.3 The subcommittee with jurisdiction is not aware of any similar ISO standard. 1.4 This standard does not purport to address all of the safety concerns 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. |
