Annotation of standard text ASTM D3667-16(2022) :

This specification covers the general requirements for materials used in rubber seals of flat-plate solar collectors, except vertically mounted passive collectors. Particular applications may necessitate other requirements that would take precedence over these requirements when specified. The rubber seals are classified into types, grades, and classes: type C - intended for use in cold climates, and type W - intended for use in warm climates; grades 2, 3, 4, 5, 6, 7, and 8 that differ in hardness properties; class PS - preformed rubber seal, and class SC - sealing compound. Seals shall be rubber vulcanizates conforming to the requirements prescribed. The adhesion, volatiles lost, and volatiles condensable shall be tested to meet the requirements prescribed.

Additional information

1. Scope

1.1?This specification covers the general requirements for materials used in rubber seals of flat-plate solar collectors, except vertically mounted passive collectors. Particular applications may necessitate other requirements that would take precedence over these requirements when specified.

1.2?The design requirement pertains only to permissible deflections of the rubber during thermal expansion or contraction of the seal in use and the tolerances in dimensions of molded and extruded seals.

1.3?This specification does not include requirements pertaining to the fabrication or installation of the seals.

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

1.5?The following safety hazards caveat pertains only to Section 9, Test Methods, of this specification: 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.

1.6?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.
