CEC Certification

As an accredited testing laboratory, we’ve helped thousands of manufacturers complete energy efficiency testing for their products and achieve California Energy Commission (CEC) certification.

1. CEC certification

The California Energy Commission (CEC) is a state agency dedicated to reducing energy consumption and promoting renewable energy sources. As part of their mission, they established the CEC Certification program to ensure that certain products meet energy efficiency standards set by the Appliance Efficiency Regulation. The regulation specifies energy efficiency requirements, measurement methods, and phased implementation plans for 58 categories of electrical products. According to the requirements of this regulation, electrical products must be tested by accredited laboratories in accordance with the corresponding regulations or standards in the United States, and can only be sold in California after approval.
