Approvals and compliance

From the manufacturer's datasheet for this series

United States

  • UL

    UL Listing or Recognition means UL Solutions tested samples against the applicable UL safety standard and audits the factory that builds them. A UL file number is the usual evidence an inspector or specifier asks for in North America.

Canada

  • CSA

    Certification to a CSA C22.2 standard, the Canadian counterpart of the UL series. Datasheets cite the specific C22.2 number, which is how you tell a power-supply certificate from a luminaire-controlgear one.

Europe

  • TÜV

    A TÜV certificate is third-party testing against the European EN standard. It is the evidence behind a CE declaration rather than a replacement for it: CE remains the manufacturer's own declaration, and the TÜV report is what makes that declaration defensible.

China

  • CCC

    China Compulsory Certification. Mandatory for the product categories in its scope; where it applies, a shipment without it is not clearable. Certification is against the GB standard the datasheet cites.

Taiwan

  • BSMI

    Taiwan's mandatory inspection mark, issued against a CNS standard. CNS 15598-1 is the CNS transposition of IEC 62368-1, which is why the two numbers usually appear together.

Eurasian Economic Union

  • EAC

    Conformity with the Eurasian Economic Union technical regulations, covering Russia, Belarus, Kazakhstan, Armenia and Kyrgyzstan. TP TC 004 is the low-voltage regulation and TP TC 020 the electromagnetic-compatibility one, so which number appears tells you what was assessed.

India

  • BIS

    Registration under India's Compulsory Registration Scheme, against an IS standard. IS 13252 is the Indian transposition of IEC 60950-1 and IS 15885 of IEC 61347, so the IS number identifies the product category.

South Korea

  • KC

    Korea Certification, mandatory for electrical equipment in scope. The KC number mirrors the IEC standard it is based on, so KC 62368-1 is assessment against the Korean adoption of IEC 62368-1.

Japan

  • PSE

    Conformity with Japan's Electrical Appliance and Material Safety Act. Japanese datasheets cite a J-prefixed standard such as J62368-1, which is the Japanese deviation-adjusted version of the IEC text.
