ETL is the abbreviation of the US Electronic Testing Laboratories. ETL was founded by the American inventor Edison in 1896 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, or test and issue composite certification marks according to UL standards or US national standards and CSA standards or Canadian standards at the same time. The "us" on the lower right indicates that it is applicable to the United States, the "c" on the lower left indicates that it is applicable to Canada, and both "us" and "c" are applicable to both countries. Any electrical, mechanical or electromechanical product with the ETL mark indicates that the product has met the minimum requirements of the generally recognized US and Canadian product safety standards, and it has been tested and meets the relevant product safety standards; it also means that the production factory agrees to accept strict regular inspections to ensure the consistency of product quality and can be sold to the US and Canadian markets. ETL also requires that its production site has been inspected and the applicant agrees to conduct regular follow-up inspections on its factory to ensure that the product always meets this requirement.
Factory inspection: US ETL certification requires 4 inspections, Canada 2 inspections per year; 4 inspections per year for both.
Until 2013, there are two ways to obtain ETL certificates. One is through CB test report transfer, and you can also apply directly. The documents required to be submitted are as follows:
1. Application form
2. CB test certificate and report copy (not required for direct application)
3. Samples
4. Other relevant test results and product data, such as: product manuals, photos, component lists, etc. (If the report is transferred through CB, a difference test is required)
1) Leakage current test: The sample used for leakage current test has not been tested before other tests
2) Normal temperature rise: Test method: Thermocouple: The standard requires the use of 24-30AWG thermocouples (30AWG currently used in the laboratory)
3) Post-humidity leakage current test: General test conditions: T= 32+/-2°C, RH= 88 ±2%. Duration: After 48 hours, take out for leakage current test Test conditions T=20~30 °C, RH=93+/-3%
4) Withstand voltage test: Generally, products without double insulation and grounding requirements: 1000 V / 1 minute (the target voltage rise time of the equipment is set to 5 seconds, the cutoff current is set to 8.3 mA, and then maintained at the target voltage for 1 minute)
ETL certification is the certification required for products exported to the United States and Canada. The ETL mark indicates that the product has passed the accreditation test of the US NRTL and/or Canadian SCC. The ETL mark is recognized to have the same validity as the UL or CSA mark and complies with the relevant safety standards. A product with the ETL listing mark means that it has met the minimum requirements of the product safety standards. In addition, the ETL mark also indicates that the manufacturer's production site meets a certain range of standard requirements and has been regularly followed up by factory audits to ensure continued consistency.
