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.

International

  • CB Scheme

    A CB Test Certificate reports testing against the IEC standard and is accepted by member certification bodies as the basis for a national approval. It shortens a new-country approval rather than granting market access by itself, so it is the most useful item on this list when you are entering a market that is not shown here.

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.

    Covers only part of this series: only for 12V,24V

An approval above is held by only some models in this series. The datasheet's own wording is quoted beside the mark; read it against this part number, and ask us for the certificate if your approval process needs it.

  • IS13252

Designed to reference

The datasheet lists these as design references. The series was built to them but has not been certified to them, so do not treat them as approvals.

Read the datasheet's exact wording

UL508, EAC TP TC 004 , BIS IS13252(Part1)(only for 12V,24V) approved, IEC62368-1 CB approved by SIQ; Design refer to BS EN/EN62368-1, AS/NZS 62368.1(meet BS EN/EN60204-1)

Reproduced unedited from the manufacturer's datasheet. Where an approval covers only some models, the wording says so. Ask us for the certificate itself if your approval process needs it.
