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.
Note 18212;Practices G151 and G155 are performance-based practices that replace Practice cited in previous versions of D3667. Practice described very specific designs for devices used for xenon arc exposure. The apparatus described in Practice is covered by the practices that replace it.
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 and health practices and determine the applicability of regulatory limitations prior to use.
