UL, VDE, CCC and other certifications

Where to find our Compliance doucments

All our Compliance Certificates and Approvals are all attached in our Product Catalog at the Model Series Line (MSL) level as a resource.



To design and manufacture electrical products for today's marketplace, you need to "think global." This is especially true when it comes to product safety certification. 

Mersen has circuit protection products to help you meet every major standard in every country. We work with regulatory bodies the world over to test and certify our products, so you can choose components that will meet the product safety requirements of the markets you want to reach.

Evidence of these approvals are the certification marks found imprinted on our products. Here are some of the more common marks and what they mean:

UL Listed Mark

The mark most familiar in the U.S., the UL Listed Mark is issued by Underwriters Laboratories. It signifies that a product has been tested by a Nationally Recognized Testing Laboratory (NRTL) and met the requirements of widely accepted product safety standards. For more information, visit www.UL.com. UL Listed products are also manufactured under the UL Follow-Up Services program, which means UL will periodically retest random samples from a manufacturer's inventory to ensure that the product continues to comply with standards and perform within accepted levels of operation.

UL Recognized Mark
Products bearing this mark are generally components of a product that will later be tested as a whole to obtain a UL Listed Mark. Using UL Recognized components does not ensure an automatic UL listing, however. The complete final product must be tested as a unit. To learn more, visit www.UL.com.

VDE (Verband der Elektrotechnik)
As a neutral and independent German organization, the  VDE Testing and Certification Institute carries out the testing of electrotechnical products, components and systems, according to DIN VDE standards and harmonized European standards, and bestows the VDE Certification Mark which is recognized and respected worldwide as a guarantee of quality and safety.

CCC (China Compulsory Certificate)
The CCC certificate was introduced in 2002 and applies to  low voltage goods imported in China as well as to products manufactured in China. A follow up in the manufacturing facility as for other major standards is operated in Europe and North Africa by VDE. 

CE Mark and Declaration of Conformity

CE Mark is required for any category of products listed in the Low Voltage European Directive and intended to be sold all over the European Union.

Declaration of Conformity is the commitment of the manufacturer or of the importer of the product to having achieved the complete test program of the European standards declared in the document.

Type approvals in the field of shipbuilding

Since the beginning of the 20th century, and a few major maritime disasters, agencies have sprung up around the world to set standards for and inspect merchant and cruise vessels.

Those agencies stay in constant contact through the IACS on a global level, and within its own country each issues certificates recognizing the suitability of products or parts for use in shipbuilding.

Their requirements include not only electrical performance tests but also stresses related to the marine environment, like vibrations, and damp and salt mist atmospheres.

Mersen also offers product ranges listed by Bureau Veritas , Lloyd’s Register , Germanisher Lloyd , Det Norske Veritas, and Korean Register.
