The CE mark states that a product is compliant against all relevant europea=
n =

directives and legislations that are in the scope for that product. There a=
re =

quite a few:

EMC - Electromagnetic compatibility, emission and immunity.
LVD - Low voltage directive, electric safety against fire and shock.
ATEX - Equipment used in explosive gas and dust atmosphere.
Machine directive - Safety requirements for machines with moveable parts.
R&TTE - Radio equipment.
RoHS - Hazardous substances (including lead)
WEEE - Waste electrical and electronic equipment
TOYS - Safety of toys
And some more...

Some directives allows self-certification and some don't. Some directives h=
ave =

different levels, classes or categories where the lower ones allows self-
certification (the ATEX directive for example).

The directives normally don't state a specific standard to test against but =

there are usually harmonized standards that, when met, will guarantee =

compliance. In some cases there doesn't exist relevant standards or the =

standards that do exist can't be used on the equipment. Then compliance can=
 be =

done through a "technical construction file" where the manufacturer =

demonstrates that the product meets the requirement of the directive. The =

technical construction file also has to be assessed by a competent body. =


The directives that don't allow self-certification will require that a =

notified/competent/approved body assesses the equipment. In some cases the =

identification number of the notified body must be included on the CE mark =

(together with data, classes, categories, levels...).

The EMC directive can be self certified to standards without the use of a =

notified/competent/approved body for equipment that doesn't include a radio =

transmitter. In the this case the declaration of conformity document must l=
ist =

all of the relevant harmonized standards that have been used. By signing th=
is =

declaration the manufacturer guarantees that the product is compliant to th=
e =

directive. The manufacturer doesn't even have to keep documents that shows =

this. He actually doesn't even have to test the equipment.

Some directives exclude other directives. The ATEX directive exlude the LVD =

directive and the machine directive have it's own limits for EMC compliance =

(which can't be self certified) to name some.
