ASTM C1266-17
(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
5.1 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.

4. Summary of Test Method
4.1 The tape sealant to be tested is rolled into spherical balls of equal weight. Four spherical balls are placed between two
aluminum plates, which are then compressed. A standard weight is placed on the test assembly for 1 h at room temperature. The
height of the test assembly is measured to determine the rebound of the sample. The test assembly is then placed in an 88°C (190°F)
oven with the standard weight on it. After 24 h the height of the test assembly is measured again to determine the flow of the
sample.

5.1 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
