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.

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.
