This specification describes the properties of cold liquid applied, single-component or multicomponent, chemically curing elastomeric structural silicone sealants herein referred to as the sealant. These sealants are intended to structurally adhere components of structural sealant glazing systems. Sealants shall be classified as to types and uses: Type S; Type M; Use G; and Use O. The physical, mechanical, and performance properties of the sealant shall conform to the requirements described. The following test methods shall be performed: rheological properties; extrudability; hardness; heat aging; tack-free time; tensile adhesion; and shelf life.
1.1 Thisspecification describes the properties of cold liquid applied,single-component or multicomponent, chemically curing elastomericstructural silicone sealants herein referred to as the sealant.These sealants are intended to structurally adhere components ofstructural sealant glazing systems.
1.2 Onlythose properties for which there are industry-agreed-upon minimumacceptable requirements, as determined by available ASTM testmethods, are described in this specification. Additional propertiesmay be added as ASTM test methods for those properties becomeavailable.
1.3 Thevalues stated in metric (SI) units are to be regarded as thestandard. The values in parentheses are for information only.
1.4Committee C24, with jurisdiction over this specification, is awareof two comparable standards by other organizations: ETAG No. 002and the Chinese national standard GB16776.
1.5This international standard was developed in accordance withinternationally recognized principles on standardizationestablished in the Decision on Principles for the Development ofInternational Standards, Guides and Recommendations issued by theWorld Trade Organization Technical Barriers to Trade (TBT)Committee.
