1.1 This test method covers determination of the degree of bubble formation or surface blistering in one-part, elastomeric solvent-release type sealants when exposed to elevated temperatures.

1.2 The subcommittee with jurisdiction is not aware of any similar ISO standard.

1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.


4.1 The type and amount of solvent used in these sealants can sometimes give rise to surface bubbling (blistering) problems. The substrate used, whether porous or nonporous, will also have an effect. Although bubbling is often caused by misapplication, this test method is useful in differentiating between a sealant that develops an acceptably smooth surface and one that may have bubbling tendencies.
