Energy Efficiency Performance Testing Items
2026-09-01Energy Efficiency Performance Testing Items: Energy Efficiency Performance Testing is the core testing scope for energy-saving certifications (China Energy Label, EU ErP / Energy Label, US ENERGY STAR / 80PLUS / DLC, etc.). It can be divided into the following categories by product type.
I. Energy Efficiency Testing for Lighting Products
