ETL is North America's most dynamic safety certification mark, dating back to the electrical testing laboratory in 1896 by Thomas Edison created, with a wide range of visibility and recognition in North America. ETL mark is the world's leading quality and safety agencies exclusive logo Intertek, and get ETL logo products meet mandatory standards on behalf of North America, it can successfully enter the North American market.
Brief introduction
ETL SEMKO is part of Intertek Testing Services Ltd., the company is
the world's largest product and commodities testing organization in
North America, Europe, 93 countries in Asia, has 240 laboratories,
469 offices. ETL SEMKO provides product safety testing and
certification, EMC testing, product performance testing, while
providing a variety of industries such as pharmaceuticals, HVAC,
appliances, telecommunications, aerospace, automotive,
semiconductor, building materials, energy generation systems such
as quality management system of registration.
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.
(2) ETL Listed Mark any electrical, mechanical or electromechanical
products with a long ETL mark to show that it is tested in
accordance with the relevant product safety
related information
ETL certification is required for products exported to the US and
Canadian certification. ETL mark indicates the product has passed
the United States or Canada, NRTL and SCC approval tests. ETL mark
recognition and UL or CSA marks having equivalent effect, and
comply with the relevant safety standards. ETL Listed Mark products
have meant that it has met the minimum requirements for product
safety 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.
