Approvals and Compliances

National testing institutions are testing according to national and international standards or other generally recognized rules of technology. Their certification/approval marks confirm the observance of the safety requirements that electric appliances must fulfill.

Please be aware that the specifications nominal value used in the German part of the Schurter catalog and the data sheets, is synonymous with rated value.

The difference between these two values is a pure matter of definition. In order to avoid any unnecessary complications, we will continue to use the specifications' nominal value.

In addition to the combined UL/CSA approvals, most of the SCHURTER components are also approved by one of the European certification bodies like VDE (Germany), Electrosuisse (Switzerland), or SEMKO (Sweden). The safety testing of all these European certification bodies is based on the common European safety standards. With the harmonization effort in Europe, the different national European certification bodies have lost their importance and SCHURTER has decided to maintain only one European approval (e.g. VDE, SEV or SEMKO) in the future. The others will not be renewed once they have expired.

Because UL and CSA are not members of the CENELEC, the standards of UL and CSA are not harmonized yet with the European standards. However, UL and CSA are trying to harmonize their standards with each other. Where possible, SCHURTER will apply for the combined cULus or cURus approval.

Further to development in Asia, SCHURTER has obtained national approvals from China, Japan, and Korea.

SCHURTER products are certified according to EN / IEC standards and carry country-specific approvals in Europe.

During the last few years, European countries made much effort to reduce their approval marks to one generally accepted mark. The ENEC approval mark replaces (wherever possible) the previous approval mark. The ENEC mark is offered by all national certification bodies that signed the European certification agreement (CCA)*.

SCHURTER decided to reduce the variety of European approval marks. For new approbations of SCHURTER parts only the ENEC will be mentioned in the future:

Approvals for the US and Canada are according to the UL and CSA standards:

As UL and CSA are not a member of CENELEC these two are not according to the European approval marks. Wherever possible SCHURTER wants to acquire the combined cULus approval mark:

Since Aug. 1st. 2003 the Chinese approval mark is required for a lot of products to import to China. SCHURTER strives to get the approvals for the concerned products.

SCHURTER will check if a voluntary CQC registration can be done when a product does not apply to a Chinese standard.

SCHURTER products are suitable for audio/video, IT, and communication technology equipment according to the new application standard IEC / UL 62368-1, which replaces IEC 60065 for audio and video equipment and IEC 60950-1 for IT and communication equipment. For filters, we recommend a version with a bleed resistor for an application according to IEC/UL 62368-1. The correct use of the SCHURTER component must be checked for conformity to the standard in the end application.

The most important safety standards for equipment/installations are listed in the following:

IEC / UL 62368-1 Safety of audio, video, information technology, and office equipment

IEC 60335 Safety of household and similar electrical appliances

IEC 61010-1 Safety requirements for electronic measuring apparatus

IEC 60601 Safety requirements for electro-medical equipment
