The D Mark is a voluntary safety Mark registered and provided by UL International Demko A/S. It has been in use for more than 70 years and is a familiar symbol to consumers, retailers and manufacturers in Europe. The D Mark demonstrates that a certified product complies with requirements in:
Widely recognized throughout Europe, the ENEC (European Norms Electrical Certification) Mark is voluntary for luminaires and associated components, household appliances, consumer electronics, information technology equipment, safety transformers, couplers and connecting devices, controls and switches, capacitors and filters. It certifies the compliance of a product with the harmonized European standards. With the exception of luminaires, which is open only to manufacturers in Europe, the ENEC program is open to applicants worldwide. UL International Demko A/S is accredited to provide the ENEC Mark using the certifier identity of 15.
The ENEC+ Mark for LED products (modules and luminaires) complements the ENEC safety certification of these products with the addition of performance testing to specific European standards and relevant requirements from IEC standards. The ENEC+ scheme verifies performance claims and assesses the robustness of product design, providing an objective basis for comparing lighting products. Only products bearing the ENEC Mark and meeting the additional performance testing requirements are eligible to carry the ENEC+ Mark. UL International Demko A/S is accredited to provide the ENEC Mark as well as the ENEC+ Mark.
UL’s Marks for Europe are voluntary safety marks intended for use on products destined for the European market. If a product carries one of these marks, it means UL has determined that representative product samples comply with the requirements of this service. These requirements are primarily based on compliance with European (EN) standards. The scope of the certification is specified on the associated certificate, which is available through UL Customer Service or the product manufacturer.
UL’s Marks for Europe apply to both electrical and electronic products and components intended for use in Europe. Products carrying one of UL’s Marks for Europe are covered by our factory inspection program to determine that end products and components continue to be manufactured in compliance with the service requirements.
There are two options for UL’s Marks for Europe, as noted below.
A UL-EU Mark appearing on a product consists of:
The UL Enhanced and Smart Marks for Europe consist of:
In addition, a manufacturer’s identification, i.e., company name or trademark, as well as a product model number must always appear on the same label with the mark. Alternatively, the mark may be stamped, cast or molded into a product, provided that a manufacturer’s identification and a model number also appear on the product.
Products that are compliant with this program as well as UL’s Listing service for the United States and Canada may be eligible to bear an alternative, combined mark for all three markets.
In addition to a typical safety certification, UL also certifies certain products for functional safety. Based on a product’s application and usage, the functional safety assessment is performed in accordance with the requirements of a published and relevant functional safety standard. Functional safety is the part of overall safety that depends on the correct functioning of safety-related control systems and software. A functional safety investigation involves the evaluation of a safety critical circuit(s) in accordance with declared safety ratings relating to software, hardware, environmental stress factors (such as EMC) and safety lifecycle management processes. UL’s certification marks for functional safety are normally restricted to products that are intended to be used in a functional safety application.
The required marking elements also include the aforementioned safety level declared by a product manufacturer. UL’s Marks for functional safety certification indicate that a product provides functions to a user that can be applied in a safety-related way. Functional safety standards define safety levels as safety integrity level (SIL), automotive safety integrity level (ASIL), performance level (PL) or class. In conjunction with one of UL’s functional safety certification marks, a manufacturer identifies the functional safety standard and the SIL, ASIL, PL or Class to which a product has been evaluated.
There are various marks for functional safety certification to indicate intended use in the United States and/or Canada and/or Europe. Canadian and European safety requirements may be somewhat different from U.S. safety requirements.
All of the products carrying these marks are covered by UL’s Follow-Up Services program to determine that they continue to be manufactured in compliance with UL’s requirements.
There are two options for the marks for UL’s functional safety certification service, as noted below.
A UL Functional Safety Listing Mark appearing on a product typically consists of the following required elements:
Additionally, a UL Functional Safety Listing Mark must be accompanied by a statement identifying the functional safety standard used for evaluation, the corresponding SIL, ASIL, PL or Class to which a product was evaluated, and the sentence “See installation manual for safety functions.”
The UL Enhanced and Smart Marks for the United States and Canada for functional safety certification consist of:
Additionally, these marks must be accompanied by a statement identifying the functional safety standard used for evaluation, the corresponding SIL, ASIL, PL or Class to which a product was evaluated, and the sentence “See installation manual for safety functions.”
A product name and issue/serial number or alphanumeric control number may also appear on a certified product.
The UL GS Mark, issued by UL International Demko A/S, is a voluntary Mark used on products such as household appliances, laboratory equipment, luminaires and IT/AV equipment. Products are evaluated according to harmonized European standards. In addition to being recognized in its primary market of Germany, the GS Mark is recognized widely throughout Europe and in a variety of international markets. The associated GS Mark certificate is valid for five years.
The enhanced UL Certification Mark now bundles multiple Certifications into a single Mark; utilizes a unique identifier for easier access to information at www.ul.com/database; communicates geographic scope of certification through country codes; and describes the attributes that UL has Certified about a product.
