Introduction

ETL is the abbreviation of Electrical Testing Laboratories. The ETL laboratory was founded in 1896 by the American inventor Edison and enjoys a high reputation in the United States and around the world. Like UL and CSA, ETL can test and issue ETL certification marks according to UL standards or US national standards. It can also test and issue composite certification marks according to UL standards or US national standards and CSA standards or Canadian standards. The "us" at the bottom right means that it applies to the United States, the "c" at the bottom left means that it applies to Canada, and the "us" and "c" for both countries. Any electrical, mechanical, or electromechanical product with an ETL mark indicates that the product has met the minimum requirements for generally recognized US and Canadian product safety standards, and it has been tested to comply with relevant product safety standards; it also represents the consent of the manufacturing facility. Receive strict periodic inspections to ensure product quality consistency and can be sold to the US and Canada markets. ETL also requires that its production site has been inspected and the applicant agrees to conduct periodic follow-up inspections of its factory to ensure that the product consistently meets this requirement.
