Government order No. This not
any secret that the system technical regulations and harmonized standards was created
according the European system, i. this case necessary prove that the product
is made and distributed according the regulation another way than prove that the product is
meeting the requirements relevant standards. 22/1997 published
nowadays form government order and number them increasing continually. Then very difficult show that everything was all right, only the
standards were not used. legislative basis for the construction the most electrical products. 169/1997 electromagnetic compatibility
.e.e.VALID TECHNICAL RULES 9
between technical regulations and harmonized standards that Technical regulations constitute
part the Czech legislation and disobedience them penalized. will mention some of
them concerning electrical engineering.
There are technical regulations according the Act No.);
c) foreseeable conditions overload (overcurrent). This true that necessary usually only in
case some accident. will not speak about all them. 168/1997 low voltage equipment
is laying down technical requirements relating electrical equipment designed for low
voltage.
a) mechanical impacts and other mechanical influences;
b) expected environmental conditions (temperature, humidity, radiation etc. Harmonized standards
as well other technical standards are voluntary documents. system directives the European community and
European harmonized standards. This order
gives particular requirements concerning assessment and declaration conformity and its
annex laying down principal elements the safety objectives for electrical equipment. This advantageous keep them
because when following harmonized standards relevant technical regulation valid for product
protects the producer against braking regulation. Nevertheless possible manufacture the
product without using harmonized standards. Shortly
saying:
The general characteristics concerning safe use electrical equipment well the
manufacturers brand name shall marked it, and electrical equipment should designed
and manufactured ensure protection against the following hazards:
Hazards arising from the electrical equipment, above all, i.
a) danger physical injury other harm which might caused electrical contact direct
or indirect;
b) high temperatures, arcs radiation which would causes danger;
Hazards which may caused external influences electrical equipment, e
