Key standards & Regulations for HVAC/r Products using low GWP refrigerants

 
 
UL 60335-2-40 describes the requirements for electrical heat pumps, air conditioners and dehumidifiers, and is an ANSI/SSC-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 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.
 
 
To capture all current market changes, ease global access and simplify testing, UL Solutions is also transitioning their traditional Standards - including UL 1995, the Standard for Heating and Cooling Equipment, and UL 484, the Standard for Room Air Conditioners - to align with harmonized International Electrotechnical Commission (IEC) standards.
 
In this continuously changing scenario, it's important to highlight the key standards and regulations to consider for evaluating HVAC/R products using low GWP or flammable refrigerants.
