gives particular requirements concerning assessment and declaration conformity and its
annex laying down principal elements the safety objectives for electrical equipment. Nevertheless possible manufacture the
product without using harmonized standards. 168/1997 low voltage equipment
is laying down technical requirements relating electrical equipment designed for low
voltage. 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) mechanical impacts and other mechanical influences;
b) expected environmental conditions (temperature, humidity, radiation etc. will mention some of
them concerning electrical engineering.

c) foreseeable conditions overload (overcurrent). Harmonized standards
as well other technical standards are voluntary documents. 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.VALID TECHNICAL RULES 9
