ETL is the abbreviation of Electrical Testing Laboratories in the United states. ETL laboratory is from the United States,The inventor of Edison, founded in 1896, enjoyed a high reputation both in the United States and around the world. Like UL, CSA, ETL according to the UL standard or national standard test issued by the ETL certification mark, but also in accordance with the UL standards or national standards and CSA standards or Canada standard test issued by the composite certification mark. The "us" on the lower right means "" for the United States. The "C" at the lower left means "Canada", while "us" and "C" are applicable in all countries
Application standards
Any mechanical or electrical, mechanical and electrical products as long as with the ETL logo indicates that this product has reached the minimum required by generally accepted the United States and Canada product safety standards, it has been tested in accordance with the relevant product safety standards.
ETL also requires that its production sites have been inspected and that the applicant agrees to conduct regular follow-up inspections of their factories to ensure that the product meets the requirements.
ETL Basic test methods
1) leakage current test: used as a model for leakage current test, no other tests before the test
2) normal temperature rise: Test and test method: thermocouple: Standard requires 24-30AWG thermocouple (30AWG used in laboratory)
3) after the tide leakage current test: General test conditions: T=, 32+/-2 degrees C, RH= 88 + 2%. duration: 48 hours after completion, take out leakage current test, test conditions T=20~30 degrees C, RH=93+/-3%
4) withstand voltage test: the product is generally insulated and grounded products: 1000 V / 1 minutes (device target voltage, climbing time is set to 5 seconds, set a cut-off current of 8.3 mA, and then keep 1 minutes at the target voltage)
The difference between UL and ETL
Both UL and ETL represent products tested through the national accredited test laboratory (NRTL) and meet the corresponding safety standards. So the real difference is service. As a ETL customer, you can enjoy customized testing, inspection and certification services, quick operation cycle and flexible working style. We are working closely with our customers so that your products will enter the market faster, more smoothly and more efficiently.ETL certification and UL certification of North American market access to the same effect, but the ETL certification costs much lower than the UL certification, generally half, only UL certified and ETL certified product testing by the CB test report, can save the testing cost many for you.ETL certification time is much shorter than UL certification, in particular cases, ETL can be issued first, and then Factory review, export of your products in order to save valuable time.
