CE Certification
Conformite Europeenne marking required for electrical equipment in the European Economic Area.
CE marking certifies equipment meets EU safety, health, and environmental requirements. For transformers, key directives: Low Voltage (2014/35/EU), EMC (2014/30/EU), and RoHS.
Requires compliance with harmonized standards, typically IEC 60076 series. Process: technical documentation, conformity assessment, CE marking, Declaration of Conformity.
Mandatory for European market. See our detailed CE certification guide for step-by-step procedures.
QDTB provides full CE certification documentation for European exports, with type testing per IEC standards at accredited laboratories.
