UL Solutions extends leak testing to China

USA/CHINA: UL Solutions has announced new testing capabilities for low GWP refrigerants at its laboratory in China.

UL standards have been updated to establish new requirements regarding flammable refrigerant leak-detection systems. This includes A2L and A3 classifications of refrigerants. 

The new testing capabilities at UL Solutions’ Zhongshan facility for flammable refrigerant detection systems and sensors are based on UL standards for electrical heat pumps, air conditioners, dehumidifiers and other household items, as well as for commercial refrigerating appliances and ice makers.

The new custom testing capabilities include evaluating refrigerant sensor performance to achieve UL component recognition, which supports UL certification. UL Solutions can also evaluate the location and configuration of refrigerant leak-detection systems that incorporate refrigerant sensors. In addition, HVACR manufacturers can use test results to support product research and development activities.

“Manufacturers in Greater China and the Asia Pacific region represent a significant portion of manufacturers supplying heating, ventilation, air conditioning and refrigeration products to the North American market and other markets that adopt UL Standards,” said Karine Johnfroe, vice president and general manager of the Built Environment group at UL Solutions. 

“This investment provides a holistic solution for manufacturers to demonstrate product performance and meet requirements for refrigerant leak detection in pursuit of environmental sustainability goals.”
