  • SCOPE

    1 Scope

    1.1 These requirements cover refrigerant recovery and recycling equipment to be employed in accordance with the National Electrical Code, NFPA 70 and include battery operated equipment.

    1.2 These requirements apply to equipment intended for indoor or outdoor use or both.

    1.3 These requirements do not cover equipment rated more than 600 volts or employing a universal motor rated more than 250 volts or intended for installation and use in a hazardous (classified) location.

    1.3.1 These requirements cover recovery/recycling equipment intended for use with a flammable refrigerant when investigated to the requirements in Supplement SB.


    1.3.1 added October 11, 2013

    1.4 Refrigerant recovery/recycling equipment intended for use with commercial refrigerant systems, other than automotive, is judged on the basis of compliance with the requirements in this standard, insofar as they are applicable, and further examination and test to determine whether the equipment is acceptable for the purpose.
