ETL Listed An electrical, mechanical or electro-mechanical product bearing the North American ETL Listed mark signifies that it was tested and meets the minimum requirements of prescribed product safety standards. Moreover, the mark indicates that the manufacturer's production site conforms to a range of compliance measures and is subject to periodic follow-up inspections to verify continued conformance. A product bearing the ETL Listed mark with the "us" identifier at the 4 o'clock position has been tested and deemed compliant to U.S. product safety standards only. An ETL Listed mark with a "c" identifier at the 8 o'clock position means the product bearing it complies with Canadian product safety standards only. And an ETL Listed mark with both "us" and "c" identifiers at the 4 o'clock and 8 o'clock positions respectively, signifies that the product bearing the mark complies with both U.S. and Canadian product safety standards.

ETL Verified An electrical, mechanical or electro-mechanical product bearing the ETL Verified mark is proof that it was tested and complies with the minimum requirements of a prescribed industry standard. As each industry standard's testing criteria and follow-up provisions vary, consult with the administration association for specific program requirements. The ETL Verified mark is widely used in the cabling products industry as evidence of compliance with a number of its association testing programs.

CE Marking The CE mark is a mandatory European marking for certain product groups to indicate conformity with the essential health and safety requirements set out in European Directives. The letters 'CE' are an abbreviation of Conformité Européenne, French for European conformity. The CE mark must be affixed to a product if it falls under the scope of the approx. 20 so called 'New Approach' Directives. Without the CE marking, and thus without complying with the provisions of the Directives, the product may not be placed in the market or put into service in the fifteen member states of the European Union and Norway, Iceland and Liechtenstein. However, if the product meets the provisions of the applicable European Directives, and the CE mark is affixed to a product, these countries may not prohibit, restrict or impede the placing in the market or putting into service of the product. Thus, CE marking can be regarded as the products trade passport for Europe.

INTERTEK Worldwide EMC Verification Mark The product with this mark on it has been certified by ITS ETL SEMKO.
