▍What is cTUVus & ETL CERTIFICATION?
OSHA (Occupational Safety and Health Administration), affiliated to US DOL (Department of Labor), demands that all products to be used in workplace must be tested and certificated by NRTL before being sold in market. Applicable testing standards include American National Standards Institute (ANSI) standards; American Society for Testing Material (ASTM) standards, Underwriter Laboratory (UL) standards, and factory mutual-recognition organization standards.
▍OSHA, NRTL, cTUVus, ETL and UL terms definition and relationship
OSHA: Abbreviation of Occupational Safety and Health Administration. It is an affiliation of US DOL (Department of Labor).
NRTL： Abbreviation of Nationally Recognized Testing Laboratory. It is in charge of lab accreditation. Up to now, there are 18 third-party testing institutions approved by NRTL, including TUV, ITS, MET and so forth.
cTUVus： Certification mark of TUVRh in North America.
ETL： Abbreviation of American Electrical Testing Laboratory. It was established in 1896 by Albert Einstein, the American inventor.
UL： Abbreviation of Underwriter Laboratories Inc.
▍Difference between cTUVus, ETL & UL
| Item | UL | cTUVus | ETL |
| Applied standard |
Same |
||
| Institution qualified for certificate receipt |
NRTL (Nationally approved laboratory) |
||
| Applied market |
North America (US and Canada) |
||
| Testing and certification institution | Underwriter Laboratory (China) Inc performs testing and issue project conclusion letter | MCM performs testing and TUV issues certificate | MCM performs testing and TUV issues certificate |
| Lead time | 5-12W | 2-3W | 2-3W |
| Application cost | Highest in peer | About 50~60% of UL cost | About 60~70% of UL cost |
| Advantage | An American local institution with good recognition in US and Canada | An International institution owns authority and offers reasonable price, also be recognized by North America | An American institution with good recognition in North America |
| Disadvantage |
|
Less brand recognition than that of UL | Less recognition than that of UL in certification of product component |
▍Why MCM?
● Soft Support from qualification and technology: As the witness testing lab of TUVRH and ITS in North American Certification, MCM is able to perform all types of testing and provide better service by exchanging technology face to face.
● Hard support from technology: MCM is equipped with all testing equipment for batteries of big-sized, small-sized and precision projects (i.e. electric mobile car, storage energy, and electronic digital products), able to provide overall battery testing and certification services in North America, covering standards UL2580, UL1973, UL2271, UL1642, UL2054 and so forth.
Looking up in the National Public Service Platform for Standards Information, we will find out a series of standard formulation and revision led by China Electric Power Research Institute about electrochemical storage have launched. It involves the revision of lithium-ion battery standard for electrochemical energy storage, the technical regulation for mobile electrochemical energy storage system, the management regulation for grid connection of user-side electrochemical energy storage system, and the emergency drill procedure for electrochemical energy storage power station. Various aspects are included such as battery for electrochemical system, grid connection technology, current converter technology, emergency treatment, and communication management technology.
As Double Carbon Policy drives new energy development, to ensure the smooth development of new energy technology has become the key. The development of standards thus springs up. Otherwise, the revision of series of electrochemical energy storage standards indicates that electrochemical energy storage is the focus of new energy development in the future, and the national new energy policy will lean to the field of electrochemical energy storage.
The standards drafting units include National Public Service Platform for Standards Information, State Grid Zhejiang Electric Power Co., Ltd.- the Electric Power Research Institute, and Huawei Technologies Co., LTD. The involvement of Electric Power Research Institutes in the standard drafting indicates that the electrochemical energy storage will be the focus in the field of electric power application. This concerns about energy storage system, inverter and interconnection and other technologies..
Huawei’s participation in the development of the standard could pave the way for further development of its proposed digital power supply project, as well as Huawei’s future development in electric energy storage.
