GB/T 32710.2-2016 "Safety Specifications for Environmental Test Instruments and Equipment - Part 2: Low-Temperature Thermostatic Circulating Devices" stipulates the safety requirements for low-temperature thermostatic circulating devices. It covers aspects such as the safety of refrigeration systems, electrical safety, temperature control safety, and circulation pipeline safety. Specific indicators are defined, including refrigeration compressor protection, low-temperature medium leakage prevention, insulation resistance, temperature uniformity, among others. The standard also includes requirements for inspection methods, labeling, and instruction manuals. It applies to the design, production, and inspection of low-temperature thermostatic circulating devices, standardizing safety management during refrigeration and circulation processes to prevent risks such as low-temperature frostbite, electrical failures, and medium leakage.
