ASTM C1266-02(2011)
(Test Method)Standard Test Method for Flow Characteristics of Preformed Tape Sealants
Standard Test Method for Flow Characteristics of Preformed Tape Sealants
SIGNIFICANCE AND USE
Tape sealants are tacky, deformable solids, which are used under compression between two or more surfaces of similar or dissimilar substrates in a variety of sealing applications. These tapes are normally supplied in a roll form with a release paper interlever and are hand pressed against a fixed substrate. This procedure is designed to give an indication of the flow characteristics of a tape sealant under controlled temperature and aging conditions with a specified load.
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.

Flow Characteristics of Preformed Tape Sealants
This standard is issued under the fixed designation C1266; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope After 24 h the height of the test assembly is measured again to
determine the flow of the sample.
