(CTC) successfully obtained the CB Testing Laboratory Certificate from the International Electrotechnical Commission IECEE, becoming a full member of the IECEE CB Scheme.

Since preparations began in 2015, all management, technical personnel, and inspectors of the PV Center have devoted substantial effort and overcome numerous difficulties. They carefully studied every standard requirement and technical detail, improved test operations accordingly, and strived for excellence. With the guidance and assistance of the expert team from TÜV NORD Germany, the PV Center ultimately passed the on-site assessment and successfully obtained the CB Testing Laboratory Certificate. CPTC becoming a CB Testing Laboratory means that the testing level and quality management level of the CPTC PV Center have been recognized by international experts, and that it has successfully entered the ranks of international laboratories. The CB test reports it issues will also be mutually recognized by IECEE member countries, helping enterprises enter the international market more conveniently and quickly.
