▍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

▍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.

Korea Agency for Technology and Standards (KATS) of MOTIE is promoting the development of the Korean Standard (KS) to unify the interface of Korean electronic products into a USB-C type interface. The program, which was previewed on 10 August, will be followed by a meeting of standard in early November and will be developed into a national standard as early as November.Previously, the EU has required that by the end of 2024, twelve devices sold in the EU, such as smartphones, tablets and digital cameras need to be equipped with USB-C ports. Korea did so to facilitate domestic consumers, reduce electronic waste, and ensure the competitiveness of the industry. Considering the technical characteristics of USB-C, KATS will develop Korean national standards within 2022, drawing on three of the 13 international standards, namely KS C IEC 62680-1-2, KS C IEC 62680-1-3, and KS C IEC63002.On 6 September, Korea Agency for Technology and Standards (KATS) of MOTIE revised the Safety Standard for Safety Confirmation Object Lifestyle Products (Electric Scooters). As personal electric two-wheeled vehicle is constantly updated, some of them are not included in the safety Management. In order to ensure the safety of consumers and the development of related industries, the original safety standards were revised. This revision mainly added two new product safety standard, “low-speed electric two-wheelers” (저속 전동이륜차) and “other electric personal travel devices (기타 전동식 개인형이동장치)”. And it is clearly stated that the maximum speed of the end product should be less than 25km/h and the lithium battery needs to pass the KC safety confirmation.
