1.1 This specification covers the general requirements for the rubber seals used in solar energy systems employing air-heat transport. Examples are duct and damper seals. Particular applications may necessitate other requirements that would take precedence over these requirements when specified. Note 1—Rubber seals for the collector are covered in Specifications D 3667 and D 3771. 1.2 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 the standard. 1.5 The following safety hazards caveat pertains only to the test methods portion, Section 10, of this specification: This standard does not purport to address the safety concerns 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. |
