UL Listing Mark
This is one of the most common UL Marks. If a product carries this Mark, it means UL found that samples of this product met UL's safety requirements. These requirements are primarily based on UL's own published Standards for Safety.

C-UL Listing Mark
This mark is applied to products for the Canadian market. The products with this type of mark have been evaluated to Canadian safety requirements, which may be somewhat different from U.S. safety requirements.

C-UL / US Listing Mark
UL introduced this new Listing Mark in early 1998. It indicates compliance with both Canadian and U.S. requirements.

Recognized Component Mark for Canada and the United States
These are marks consumers rarely see because they are specifically used on component parts that are part of a larger product or system. These components may have restrictions on their performance or may be incomplete in construction. Products intended for Canada carry the Recognized Component mark "C."

UL Listing vs. Recognition. What's the difference?
A product is UL Listed if the UL Listing Mark is on the product, accompanied by the manufacturer's name, trade name, trademark or other authorized identification.

A UL Listing Mark on a product is composed of four elements: the "UL in a circle Mark, the word "LISTED in capital letters, an alpha-numeric control number, and the product name. Sometimes the UL file number is used as company identification. The UL Listing Mark on a product is the manufacturer's representation that samples of that complete product have been tested by UL to nationally recognized Safety Standards and found to be free from reasonably foreseeable risk of fire, electric shock and related hazards and that the product was manufactured under UL's Follow-Up Services program.

If you do not find a UL Listing Mark on the product, you may find, on closer examination, that some of the individual components have the UL Recognized Component Mark . The UL Recognized Component Mark means that the component alone meets the requirements for limited, specified use. UL's Component Recognition Service covers the testing and evaluation of component products that are incomplete or restricted in performance capabilities. These components will later be used in complete end products or systems Listed by UL.

UL's Component Recognition Service covers millions of components, such as plastics, wire and printed wiring boards, that may be used in either very specific, or a broad spectrum of end-products, or even components such as motors or power supplies. These components are not intended for separate installation in the field they are intended for use as components of complete equipment submitted for investigation to UL. Component/end-product compatibility is the critical link between certification of a component and certification of the end product in which the component is used.

The CSA mark may appear alone or with indicators. If it appears alone, it means that the product is certified for the Canadian market, to the applicable Canadian standards.

Many products seeking entry into the European Union must comply with the European Directives and bear the CE Marking. The CE Marking is the manufacturers self-declaration, showing compliance with all applicable directives.

The CCC Mark is a labeling requirement for select products entering China. Essentially, the CCC Mark verifies to customs officials that a product complies with safety and quality requirements set by the Chinese government. Compliance is demonstrated by the manufacturer affixing the CCC Mark to their products.

The Low Voltage Directive (LVD) sets out the essential protection requirements, with relevant technical details being defined by standards-making organizations.  The LVD applies to Electrical Equipment for use with a voltage rating of between 50 and 1000 V for alternating current (A.C.) and between 75 and 1500 V for direct current (D.C.).

Therefore, this Directive is called often "Low Voltage Directive" which applies to the vast majority of electrical equipment in everyday use. This Electrical Equipment may be placed on the market only if it does not endanger the safety of people, domestic animals or property.

The main features of this directive are that:

(a) The Low Voltage Directive is not designed to impose safety standards. Its primary purpose is to ensure free trade through the removal of technical barriers.
(b) Conformity with standards is not compulsory, but it can be used as one means to demonstrate compliance with the safety principles enshrined in the directive. 
(c) The Low Voltage Directive covers other aspects of safety, including mechanical aspects.

From a manufacturer's perspective, there are different ways in order to demonstrate conformity, with the most common being a manufacturers declaration of compliance, or a mark by a notified 3rd party standards organization. 

A manufacturers declaration is in itself sufficient to provide evidence of conformity to the LVD, but a mark by a 3rd party independent “notified body” testing agency, is also acceptable too.

Finally, as of  January 1st 1997, application of the CE Marking to a product will indicate that the equipment complies with the requirements of the LVD.

DEMKO's D-Mark represents electrical product safety for a great majority of consumers. The D-Mark is recognized throughout the EU as a reputable European third-party mark of electrical product safety.

International "emc-Mark"
The International "emc-Mark" appears on products meeting the electromagnetic compatibility requirements of Europe, the United States, Japan, Australia, or any combination of the four. In the United States, some types of products can't be sold without proof of compliance to U.S. electromagnetic compatibility requirements.

C-tick Mark
Applying the C-tick mark to a product indicates compliance with Australian EMC regulations

TÜV-Mark for products
TÜV Product Service mark demonstrates that you meet European Health and Safety Requirements of safety directives.

VDE Mark
The VDE Mark indicates conformity with the VDE standards or European or internationally harmonized standards resp. and confirms compliance with protective requirements of the applicable EC Directive(s).

The BIA is a test and certification body affiliated to the testing and certification system BG-PRÜFZERT of the German institutions for statutory accident insurance and prevention (BG means Berufsgenossenschaft). The BIA has received accreditation from the central office of safety technology of the Länder (ZLS).

The BIA performs a test and certification body for products under the terms of the EC Directive for personal protective equipment.
