Standard Specification for Rubber Seals Used in Flat-Plate Solar Collectors
|Publication Date:||1 December 2005|
|ICS Code (Seals, glands):||21.140|
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 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.
This specification does not include requirements pertaining to the fabrication or installation of the seals.
NOTE 1-Practices G 151 and G 155 are performance-based practices that replace Practice G 26 cited in previous versions of D 3667. Practice G 26 described very specific designs for devices used for xenon arc exposure. The apparatus described in Practice G 26 is covered by the practices that replace it.
The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
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.
