Any electrical, mechanical or electromechanical products with a long ETL inspection mark to show that it is tested in accordance with relevant industry standards. Each industry has different testing standards, so the requirements for specific products must be accountable to professional advice. ETL inspection mark is widely used in cable products that passed the relevant tests.
In most parts of the United States, approval of electrical products is mandatory. ETL ETL Testing Laboratories means (ETL Testing Laboratories Inc). ETL Listed products are made of "competent authority having jurisdiction" (Authorities Having Jurisdiction) recognized, can be considered "Approved."

ETL basic test method
^{leakage current test: leakage current test is used as a model Before the test did not conduct other tests
2), normal temperature: Test Test Method: thermocouple: Standard requires 24-30AWG thermocouple, (currently laboratory use 30AWG)
3), after the influx of state leakage current test: General Test conditions: T = 32 +/- 2 ° C, RH = 88 ± 2% Duration: 48 hours after the completion of removal do leakage tests Test Conditions T = 20 ~ 30 ° C, RH = 93 +/- 3%
4) Pressure test: general unparalleled insulation and ground product requirements: 1000 V / 1 min (target voltage equipment climb time is set for 5 seconds, set the cutoff current of 8.3 mA, and then maintained at the target voltage of 1 minute)}
 
Scope
the company
Tested in accordance with the relevant product safety standards, it represents the manufacturing plant agreed to receive rigorous and regular checks to ensure product quality and consistency, can be sold in the United States and Canada markets.
Mark
(1) ETL inspection mark any electrical, mechanical or electromechanical products with a long ETL inspection mark to show that it is tested in accordance with relevant industry standards.

In addition, ETL mark indicates the manufacturer more production sites in line with a range of standards, and by learning facility periodically review the follow-up to ensure continued consistency. ETL appeared more than 100 years. ETL these three letters in 1896 founded by inventor Mr. Edison electrical testing laboratory (Electrical Testing Labs) for short. ETL stands for innovation, influential, independent product testing and public experience.

The difference between UL and ETL
UL and ETL represent products through Nationally Recognized Testing Laboratory (NRTL) test, meet the appropriate safety standards. So the real difference is service. As ETL customer, you can enjoy customized testing, inspection and certification services, fast and flexible operating cycle work. We are working with customers to create a way of working more closely so that your products faster and more smoothly, more efficient access to markets.
ETL certification and UL certification have the same access to the effectiveness of the North American market, but the ETL certification costs much lower than the UL certification, UL certification generally only half, but, ETL certified product testing by the CB test report, you can save a lot of testing costs.
ETL certification time is much shorter than the UL certification, under special circumstances, ETL certification can first, then the factory inspection, to export your product to save valuable time.
