Globally, most countries and regions have established their own product certification systems and standards, with different marks indicating compliance with relevant regulations. For instance, UL represents safety testing and certification by Underwriters Laboratories in the United States; the FCC Declaration of Conformity is a mandatory compliance mark for electronic equipment manufactured or sold in the U.S., demonstrating adherence to Federal Communications Commission standards on electromagnetic interference; CE is the safety certification for the European Union; and RCM (Regulatory Compliance Mark) signifies compliance with all applicable technical and record-keeping requirements set by the Australian Communications and Media Authority, etc.
