ETL is North America's most dynamic security authentication marks, history can be traced back to Thomas Edison in 1896 created electrical testing laboratory, has wide popularity and recognition in North America. The ETL logo is the world's leading quality and security agencies Intertek Intertek's exclusive logo, get the ETL logo products on behalf of North America to meet the mandatory standards, can smoothly enter the north American market sales.
ETL SEMKO is Intertek Testing Services co., LTD., a part of, the company is the world's largest
Goods and commodity inspection organization, in North America, Europe and Asia in 93 countries with 240 laboratories and 469 offices. ETL SEMKO provides for product safety testing and certification, EMC testing, product performance testing, at the same time to provide such as medicine, HVAC, appliance, telecommunication, aerospace, automation, various industry such as semiconductor, building materials, energy generation system of quality management system of registration
Any electrical, mechanical, or mechanical and electrical products as long as with ETL inspection marks indicate that it is tested in accordance with the relevant industry standards. Every industry has a different test standard, so the requirement for a specific product must consult a professional. ETL inspection marks are widely used in cable products, suggests that passed the test.
Most areas in the United States, electrical product approval is mandatory. ETL is refers to the ETL Testing laboratory company (ETL Testing Laboratories Inc). ETL listed products are made from "competent authority of the judicial power" (the Authorities Having Jurisdiction) acknowledges, "approved" can be thought of.
The factory inspection
After the ETL factory inspection is required before issuing, each quarter will not regular follow up factory
ETL certification examination, fees in addition to the factory inspection fee to pay quarterly certificate licence fee.
If necessary, the inspectors can witness the product after testing or sampling test in the laboratory.
Licensed licensing certificate must sign a legal contract with ETL (service agreement), it clearly states that the responsibility of the manufacturer and continuous ETL column and the conditions of the use of the ETL logo.
Application documents
Can directly apply, submit required documents are as follows:
1. The application form
Samples of 2.
3. Other relevant test results and the product data, such as: product manuals, pictures, components list, and so on.
Laboratory is founded by American inventor Thomas Edison in 1896, in the United States and around the world enjoy high reputation. Like UL, CSA, ETL test according to UL standard or national standards issued by the ETL certification marks, also can at the same time, according to the UL standard or national standards and the CSA standard or issued by the Canadian standards test compound authentication marks. The lower right of the said "us" is applicable to the United States, the lower left corner of the "c" said applies to Canada, at the same time with "us" and "c" in the two countries.
To apply for the standard
Any electrical, mechanical, or mechanical and electrical products as long as with the ETL logo indicates that this product has reached the United States and Canada to be approved by general product safety of the minimum requirements of the standard, it has been tested in accordance with the relevant product safety standards.
ETL also requires its production site has been tested, and the applicant agree to regular follow-up inspection after the factory, to ensure that the product is always comply with this requirement.
ETL basic test method
1), the leakage current test: as the example of leakage current test no other tests were conducted before the test
2), normal temperature rise: test methods: thermocouple: standards require the use of 24 to 30 awg thermocouple, (current lab use 30 awg)
3), tide after the leakage current test: general test conditions: T = 32 + / - 2 ° C, RH = 88 + / - 2%. The last time: 48 hours after the completion of the conditions of leakage current test out do T = 20 ~ 30 ° C, RH = 93 + / - 3%
4), pressure test: general one like insulation and grounding products products: 1000 V / 1 min (equipment climb target voltage is set to 5 seconds, set the chopping current 8.3 mA, then the target voltage under 1 minute)
Scope of application
The company
After testing in accordance with the relevant product safety standards, representing the factory agree to receive the strict check, to ensure the consistency of product quality, can be sold in the United States and Canada market.
mark
(1) the ETL inspection mark any electrical, mechanical, or mechanical and electrical products as long as with ETL inspection marks indicate that it is tested in accordance with the relevant industry standards.
(2) the ETL listed mark any electrical, mechanical, or electrical and mechanical products as long as with the ETL logo shows that it is tested in accordance with the relevant product safety standards
The related content
ETL certification is needed for the products are exported to the United States and Canada. The ETL logo products have passed the NRTL and or Canada SCC recognition test. ETL mark recognition and UL or CSA mark have the equivalent effect, and in accordance with the relevant safety standards. Product with the ETL listed mark means that it has met the minimum requirements of product safety standards
