Classification of energy efficiency testing: Currently, globally renowned energy efficiency certifications include Energy Star in the United States, CEC in California, EUP in the European Union, GEMS in Australia, and China Energy Conservation Certification. European Energy Efficiency ERP: The ErP directive stipulates that energy consuming products included in implementation measures must be labeled with the CE mark in order to enter the EU market. Before obtaining the CE mark, the manufacturer or its authorized representative shall take measures to ensure that the product has passed the conformity assessment in accordance with the implementation measures and procedures, prepare technical documents related to the product conformity assessment, and issue an EC conformity declaration. Energy Star in the United States: Energy Star covers a wide range of products, including household appliances such as refrigerators, air conditioners, washing machines, dishwashers, dehumidifiers, etc; Household electronic products: such as televisions, video recorders, cordless phones, DVD products, etc; Heating and cooling equipment: such as heat pumps, boilers, central air conditioning, etc; Computers and office equipment: such as computers, monitors, printers, fax machines, copiers, all-in-one machines, etc; Lighting equipment: such as compact fluorescent lamps, exit indicator lights, ceiling fans, etc; Industrial and commercial products: such as transformers, power supplies, commercial frying pans, commercial refrigerators, etc; Large commercial buildings and newly built housing, doors and windows, etc. California Energy Efficiency CEC: CEC is the abbreviation of the California Energy Commission in the United States, which is responsible for promoting healthy competition in the energy market. The California Appliance Efficiency Regulation, implemented by the organization since 1976, is the only mandatory energy-saving regulation in the United States that can affect non-governmental consumption behavior, playing an important role in reducing energy consumption. China Energy Conservation Certification: The certification product range covers 35 types of products, including household appliances, audio and video products, information technology equipment, lighting fixtures and their accessories, industrial equipment, and building materials. They are: household appliances (10): household refrigerators, room air conditioners, unit type room air conditioners, household electric washing machines, household microwave ovens, household water storage electric water heaters, household automatic rice cookers, induction cookers, range hoods, and water dispensers; Audio and video products (2): color television broadcasting receivers, DVD/VCD disc players; Power supply product (1): external power supply; Information technology equipment (6): computers, monitors, fax machines, copiers, digital multifunctional office equipment, printers, and printing/fax integrated machines; Luminaires and their accessories (6): dual ended fluorescent lamps, self ballasted fluorescent lamps, single ended fluorescent lamps, tubular fluorescent lamp ballasts, ballasts for high-pressure sodium bulbs, AC electronic ballasts for high-pressure sodium bulbs; Industrial equipment (8): power saving devices - low-voltage distribution step-down energy-saving devices, power saving devices - motor light load voltage regulating energy-saving devices, AC power system wave arresters, volumetric air compressors, power fittings, small and medium-sized three-phase AC asynchronous motors, ventilators, and distribution transformers; Building materials (2): polystyrene foam plastic plate, external windows of buildings The above article is a partial list.
