(Test Method)Standard Test Method for Flow Characteristics of Preformed Tape Sealants
Standard Test Method for Flow Characteristics of Preformed Tape Sealants
SCOPE
1.1 This test method describes a laboratory procedure for determining the flow characteristics of preformed tape sealants after a specified time, temperature, and load.
1.2 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are provided for information purposes only.
1.3 The committee with jurisdiction of this specification is not aware of any similar specification within ISO or any other organization.
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.
