1. Scope

1.1 This classification covers silicone adhesives and sealants intended for but not limited to sealing and retaining metallic and nonmetallic component assemblies in transportation applications. The materials cure to an elastomeric state by their specified cure system and mechanism.

The classification system may serve many of the needs of industries using silicone materials. This classification is subject to revision, as the need requires; therefore, the latest revision should always be used.

1.2 This classification is intended to be a means of classifying silicone materials. It is not intended for engineering design purposes.

1.3 It is not the intent of this classification to include pressure-sensitive or hot-melt adhesives.

1.4 In all cases in which the provisions of this classification system would conflict with the referenced ASTM standard for a particular method, the latter shall take precedence.

1.5 &si-value;

The following safety hazards caveat pertains only to the test methods portion, Section , of this classification. 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.
