5.1Dimensions . See Figures 2 and 3 (above).
5.1.1 While conformance to Figures 2 and 3 is
recommended, where components do not meet the
constructional and dimensional requirements
shown, all access valves shall still interchange with
components that meet these requirements and
shall comply with all mandatory requirements to be
in conformance with this standard.
5.2Materials. Materials used for the seals on the valve
core shall be compatible for service with halogenated
hydrocarbon refrigerants and refrigerant oil for the
intended application.
Section 6. Gaging Procedures
6.1 Gaging. Figures 4 and 5 (above) show two
accepted methods of gaging the access valve body.
Section 7. Voluntary Conformance
7.1 Conformance. While conformance with this
standard is voluntary, conformance shall not be
