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.
