1.1This 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.

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

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

1.4In 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.

1.5The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6The following safety hazards caveat pertains only to the test methods portion, Section 7, 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.7This 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.
