Standard Test Method for Bubbling of One-Part, Elastomeric, Solvent-Release Type Sealants

Fecha:
2014-12-22 /Historical
Superseeded by:
Significance and Use:

The type and amount of solvent used in these sealants can sometimes give rise to surface bubbling and blistering problems. The substrate used, whether porous or nonporous, will also have an effect. Although blistering 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 blistering tendencies.

Scope:

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 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.
