CE conformity marks indicate that products comply with the requirements of relevant European health, safety, and environmental protection directives. All electrical and electronic equipment shipped to Europe must have the CE Mark to indicate that devices meet both the "General Product Safety Directive" and the "Electromagnetic Compatibility Directive". CE is an abbreviation of the French phrase "Conformité Européene", which means "European Conformity".
The CSA Mark may appear alone or with indicators. If it appears alone, it means that the product is certified for the Canadian market, to the applicable Canadian standards. If this Mark appears with the indicator "C and US" or "NRTL/C" it means that the product is certified for both the U.S. and Canadian markets, to the applicable U.S. and Canadian standards.
The International Electrotechnical Commission (IEC) is the authoritative worldwide body responsible for developing consensus global standards in the electrotechnical field. IEC is dedicated to the harmonization and voluntary adoption of these standards, supporting the transfer of Electrotechnology, assisting certification and promoting international trade. Since 1906, IEC has served the world's electrical industry, developing international standards to promote quality, safety, performance, reproducibility, and environmental compatibility of materials, products, and systems. It has also published standards for the electronics and telecommunications industries. The IEC's present membership of 51 countries includes most major trading nations. IEC standards are widely adopted as the basis of national or regional electrotechnical standards, and are often quoted in manufacturers' specifications and by users when calling for tenders. Over 2000 standards cover virtually every topic of Electrotechnology from acoustics, to medical devices, to insulating materials, to aircraft, to nuclear instruments. The IEC's membership consists of the electrotechnical standards organizations from each participating nation. The American National Standards Institute (ANSI) represents the United States.
The Institute for Interconnecting and Packaging electronic Circuits (IPC) a global trade association that includes designers, board manufacturers, assembly companies, suppliers, and original equipment manufacturers (OEMs). IPC is a member-driven organization and leading source for industry standards, training, market research and public policy advocacy.
TÜV Rheinland/Berlin-Brandenburg provides international approvals services as they relate to product safety. Products certified by TÜV Rheinland for the US market are identified by the TUVus certification mark. TÜV Rheinland of North America is also established as a Certification Organization in Canada. When the TUVus mark is coupled with the cTUV mark, the product is certified compliant for both the US and Canadian markets.
The UL listing mark denotes that samples of a product meet the safety requirements of Underwriters Laboratories (UL). These requirements are mostly based on UL's published standards for safety.
