Standard Specification for
Rubber Seals Used in Flat-Plate Solar Collectors1

This standard is issued under the fixed designation D 3667; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

This standard has been approved for use by agencies of the Department of Defense.

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 the
standard.

1.5 The following safety hazards caveat pertains only to the
test methods portion, Section 9, of this specification: This
the 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.
