Appendix B4 to Subpart F of Part 82 - Performance and Safety of Flammable Refrigerant Recovery and/or Recycling Equipment
40:21.0.1.1.1.6.1.15.24 : Appendix B4
Appendix B4 to Subpart F of Part 82 - Performance and Safety of
Flammable Refrigerant Recovery and/or Recycling Equipment
This appendix is based on the Air-Conditioning, Heating, and
Refrigeration Institute Standard 740-2016, Performance Rating of
Refrigerant Recovery Equipment and Recovery/Recycling
Equipment, and Underwriters Laboratories Standard 1963-2011
(Fourth Edition), Standard for Safety: Refrigerant
Recovery/Recycling Equipment, including Supplement SB (added
October 11, 2013), Requirements for Refrigerant
Recovery/Recycling Equipment Intended for Use with a Flammable
Refrigerant.
Section 1. Purpose
1.1 The purpose of this standard is to establish methods of
testing for rating and evaluating the performance and safety of
refrigerant recovery and/or recycling equipment and general
equipment requirements (herein referred to as “equipment”) for
contaminant or purity levels, capacity, speed and purge loss to
minimize emission into the atmosphere of designated refrigerants,
as well as safety for use with flammable refrigerants.
Section 2. Scope
2.1 This standard applies to equipment for recovering and/or
recycling flammable single refrigerants, azeotropes, zeotropic
blends, and their normal contaminants from refrigerant systems.
This standard defines the test apparatus, test gas mixtures,
sampling procedures, analytical techniques, and equipment
construction that will be used to determine the performance and
safety of refrigerant recovery and/or recycling equipment
(hereinafter, “equipment”).
Section 3. Definitions
3.1 All terms in this appendix will follow the definitions in §
82.152 and Appendix B3 to Subpart F of Part 82 unless otherwise
defined in this appendix.
3.2 All definitions used in UL 1963, including the definitions
in Supplement SB, as applicable, are incorporated by reference, see
§ 82.168.
Section 4. Evaluation of Performance
4.1 Performance Ratings. All recovery and/or recycling
equipment to be tested under this appendix must follow the
procedures and meet all requirements established in Appendix B3 to
Subpart F of Part 82 to determine the performance ratings in
addition to the safety evaluation conducted under the rest of this
appendix.
4.2 Safety. All recovery and/or recycling equipment to be
tested under this appendix must follow the procedures and meet all
requirements in Supplement SB (added October 11, 2013),
Requirements for Refrigerant Recovery/Recycling Equipment
Intended for Use with a Flammable Refrigerant in Underwriters
Laboratories Standard 1963-2011 (Fourth Edition), Standard for
Safety: Refrigerant Recovery/Recycling Equipment (incorporated
by reference, see § 82.168).
