The low electric voltage instruction (the Low Voltage Directive,
73/23/ EEC) establish in 1973,20 years before establish
for the new project (the New Approach) instruction, and
is think is the precursor of the new project concept.
LVD target for insure the safety
for low electric voltage equipments to use. The definition
of the low electric voltage equipments settles the electric
voltage as 50-1000 of hour of alternate current for the
sum, 75-1500 electricity equipmentses of the volt of hour
of direct current. Broad sense but speech, the low electric
voltage equipments includes the consumer goods and design
for the equipments operate within the scope of this electric
voltage. Include the home appliances, handicraft have, illuminates
the equipments, electric wire, electric cable and pipelines,
and go together with line equipments etc.. This instruction
includes all safe rules of this equipments, including the
protection because of the danger that the machine reason
result in.
The LVD specify the EU member nation and must adopt the
appropriate method, electricity equipments that insures
in local market the sale unlikely endanger the people safety,
also will not endanger the local animal or properties. Therefore
must attain: The equipments must carry on the design in
good way according to the safe rules Equipments must the
exactitude equip and support; The equipments must depend
on to design the purpose usage If the equipments meets the
particular safety provision of all member nations approbation,
that is match these items. Early time that LVD establish
establishes time in the CE marking. The marking of CE for
these new project instructions draft by EU in the last few
years. The instruction 93/68/ EEC modified the LVD, to meet
the need of the present. According
to the instruction 93/68/ EEC, manufacturer or authorization
in the EU the representative can draft a matches announcement,
additional CE marking on the product, mark it meets the
LVD and related provisions. Appear on market from the
product beginning, the manufacturer must reserve the technique
document for 10 years, being provided for parties concerned
to carry on examination. Match the contents that announcement.
The general contents of" match announcement "
can in the appendix of the instruction 3(B) check. Detailed
say, this announces and must include: Manufacturer or
EU inside authorize the representative's name and the
address The electricity equipments elucidation Be in conjunction
with the standard reference When it's necessary, must
include the manufacturer or it at the authorization in
the EU represents to announce to match announcement, according
to of elaborate on and consult document Authorize and
appoint the ID card that it signs clear The product (first
time) acquires the last two numeral of the CE marking
age Match announcement and must compose with at least
a kind of language with official EU. The contents of the
technique document. The technique document must include
the detailed data such as design, manufacturing and operation
etc. of the electricity equipments, evaluating whether
this electricity equipments meets the instruction provision
or not in order to. Therefore, the document must include:
General elucidation of the product Design and make the
diagram, and the illustrated manual table of the module,
sub- module, circuit...etc.. Explain the above diagram
faces and illustrates, and the elucidation document of
this electricity equipments operation. The standard detailed
list of all or parts of usages, and the part that didn't
yet rule in the standard, meet the solution of safe request
in order to. Design the calculation and carry on the check
etc., the result of inspection, the test report (from
manufacturer or the test report that the third unit put
forward), take care of the unit and the location of the
technique document. Manufacturer or its uthorization representative
in EU, from here product end manufacturing of from day,
must take care of this document for 10 years at least,
provide the government parties concerned to at any time
carry on the examination. The technique document keeps
by electronics may also, but the premise is to must carry
on the examination easily. Belong to import the factory
if manufacturer at EU have no base and have no authorization
representative, this responsibility, or at the representative
director of the EU market sale.
