CENELECisthe“EuropeanCommitteeforElectrotechnicalStandardization”jointly founded in1973
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 withEuropean market unificationin 1992, CENELECtook onthevery important task ofcreat-
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).
ECmembernationsmustusetheENstandardsfornational standardswithoutanychanges, butthey
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.
TheVDE(Germanelectricaltechnician’sassociation),establishedin1893,ismainlyresponsiblefor
carrying out safety testing and approval administration of electrical products.
Compliance withVDEstandards is not proscribed under Germanlaw, however,the extremely heavy
penalties imposedonthemanufacturerof anunapproved productwhich causes an electric-shock or
fire mean that compliance is effectively compulsory in practice.
TheVDE offers twomajor classificationsof approval:the VDEMark (belowleft) forproducts thatcan
beused independently onthemarket, andthe MonitoringMark (belowright) forcomponents thatare
built into other products. The number inside the Monitoring Mark is the VDE registration number.

Thesearethestandards of theLloyd’sRegisterofShipping, headquartered in London. AlloftheOM-
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 atthe production factory can be partially orentirely omitted when automation equipmentand
devices that have been formally approved are installed on ships.
Asageneralrule,manufacturersof approvedproducts indicatethattheproductsbeingshippedhave
been approved. (It is also acceptable to affix a label to products which require it.)
Theproducts governed bythe Electrical Appliance and MaterialControl Law (EAMCL) areelectrical
appliances generally used in the home or office. It does not apply to other industrial electrical equip-
ment.
ElectricalequipmentfallingundertheauspicesoftheEAMCLareknownas electricalappliancesand
divided into first-grade and second-grade appliances according to their dangerousness and how
widespread their use.
First-grade appliances can display thesymbolshown on theupper-left withanauthorizationnumber
and be manufactured and sold if they pass the formal authorization tests prior to manufacture. Se-
cond-gradeappliances candisplay thesymbol shownonthelower-left withan authorizationnumber
and be manufactured and sold if the manufacturer reports the main principles of manufacturing.

Reference
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.
