Low GWP services

Refrigerants with low global warming potential (GWP) may be more environmentally friendly, but they’re also considered mildly flammable. Consequently, regional regulations increasingly require HVAC appliance manufacturers to reduce their products’ greenhouse emissions. Flammable refrigerant testing is becoming a central part of the HVAC/R equipment benchmarking, testing, assessment and certification process.

Key standards and regulations for HVAC/R products using low GWP refrigerants:

  • UL/IEC 60335-2-40
    UL 60335-2-40 describes the requirements for electrical heat pumps, air conditioners and dehumidifiers, and is an ANSI/SCC-accredited U.S./Canada binational consensus safety standard. It is based on IEC 60335-2-40, the international standard that currently serves as the basis for evaluating, testing and certifying HVAC equipment designs using low GWP refrigerants in Europe and elsewhere.
  • UL/IEC 60335-2-89
    UL Solutions recently transitioned to the new harmonized Standard UL 60335-2-89, which covers UL 412, the Standard for Refrigeration Unit Coolers; UL 427, the Standard for Refrigerating Units; UL 563, the Standard for Ice Makers; and UL 471, the Standard for Commercial Refrigerators and Freezers. UL 60335-2-89 is harmonized with the IEC and covers all current market changes, easing global market access and simplifying testing for manufacturers.

Our safety science leadership, technical expertise and global network of testing laboratories can help you demonstrate compliance with regional safety standards for low GWP refrigerants in your target markets.


Increasingly, consumers, investors and professional buyers are demanding more sustainable products and services. You can meet these demands and help build stakeholder trust and loyalty by integrating sustainability into your overall business strategy.

Learn how to target and articulate your investments in environmental and social initiatives in ways that will resonate with and compel your customers, prospects, suppliers, employees, investors and communities to want to work with you.
