CENELEC is the "European Committee for Electrotechnical Standardization" jointly founded in 1973
by the EEC (European Economic Community) and EFTA (European Free Trade Association). It is
headquartered in Brussels, Belgium and currently has 18 member nations.
Faced with European market unification in 1992, CENELEC took on the very important task of creat-
ing unified European standards and is energetically proceeding with the creation of standards.
The CENELEC standards can be broadly divided into two groups: EN (European Norm) and HD
(Harmonized Document).
EC member nations must use the EN standards for national standards without any changes, but they
can use national standards that are have the same general content as the HD standards, so some
differences in content are allowed with the HD standards.
The VDE (German electrical technician's association), established in 1893, is mainly responsible for
carrying out safety testing and approval administration of electrical products.
Compliance with VDE standards is not proscribed under German law, however, the extremely heavy
penalties imposed on the manufacturer of an unapproved product which causes an electric-shock or
fire mean that compliance is effectively compulsory in practice.
The VDE offers two major classifications of approval: the VDE Mark (below left) for products that can
be used independently on the market, and the Monitoring Mark (below right) for components that are
built into other products. The number inside the Monitoring Mark is the VDE registration number.

These are the standards of the Lloyd's Register of Shipping, headquartered in London. All of the OM-
RON control components approved in LR are UMS ships, the unmanned engine-room ship classifi-
cation in the Lloyd's Register.
Unlike the safety standards such as UL, the devices are checked to ensure that they can function
sufficiently under the environmental conditions when they are used in ships.
When a device is approved, Lloyd's Register doesn't apply the passing mark on the product, but in-
cludes it on the list of approved products that it publishes every year.
Automation equipment and devices receive tests and inspections based on the provisions of the
steel-ship regulations and can be formally approved if the tests are passed.
Testing at the production factory can be partially or entirely omitted when automation equipment and
devices that have been formally approved are installed on ships.
As a general rule, manufacturers of approved products indicate that the products being shipped have
been approved. (It is also acceptable to affix a label to products which require it.)
The products governed by the Electrical Appliance and Material Control Law (EAMCL) are electrical
appliances generally used in the home or office. It does not apply to other industrial electrical equip-
ment.
Electrical equipment falling under the auspices of the EAMCL are known as electrical appliances and
divided into first-grade and second-grade appliances according to their dangerousness and how
widespread their use.
First-grade appliances can display the symbol shown on the upper-left with an authorization number
and be manufactured and sold if they pass the formal authorization tests prior to manufacture. Se-
cond-grade appliances can display the symbol shown on the lower-left with an authorization number
and be manufactured and sold if the manufacturer reports the main principles of manufacturing.

This mark is applied to products shown to conform to all relevant EC directives.
The EC directives that apply directly to this company's products are the Low-voltage directives and
EMC directives. The Mechanical directives apply indirectly.
As a general rule, the CE marking is required for final products that appear on the market, but isn't
required for the internal components in the product.
