UL certification
UL certification In the United States, it belongs to non mandatory certification, mainly testing and certification of product safety performance, and its certification scope does not include the EMC (electromagnetic compatibility) characteristics of products. Although UL certification does not belong to the scope of compulsory certification in the United States, because of its early development, it has a very high recognition in the United States, so if you want the related products to sell well in the United States, it is very necessary to do UL certification.
UL American Underwriters Laboratory was established in 1894. It mainly involves the inspection of electrical, electronic equipment, mechanical products, lamps, building materials, fire prevention equipment and chemicals. Most of the products sold in the U.S. market have UL certification or ETL certification At the same time, it is accepted by consumers. Therefore, the products related to electricity can apply for UL certification. UL logo is a safety certification mark recognized by the United States and North America. The products with this logo are equivalent to obtaining the safety and quality credit card, and its credibility has been accepted by the majority of consumers. Therefore, UL logo has become a special pass for relevant products (especially mechanical and electrical products) to enter the American and North American markets.
