Both parts of EN 50565 refer to cable types specified in EN 50525, replacing the reference to the HD 21 and
HD 22 cable types. Part 1 provides general recommendations and guidance, Part 2 covers specific guidance
for each cable type in EN 50525, like designation, constructional details, recommendations for installation,
conditions and limits of operation, temperature limits and recommended use/suitability.
This standard covers the Principle Elements of the Safety Objectives for Electrical Equipment Designed for
Use within Certain Voltage Limits (LVD - 2006/95/EC).

Introduction
This European Standard provides guidance for equipment manufacturers, installers and end-users on the
properties of low voltage electric cables, and the limitations that are deemed to be necessary in order to
safeguard life, buildings, and goods. It also gives a reasonable certainty on cable life time expectation relevant
to its application, i.e. the duration of acceptable performance considered as reasonable for a cable used in a
fixed installation for the distribution of electricity in a building is more than that for flexible cable.
It is not possible to cover all the uses that the installers or users may wish to use for a specific type of cable.
The use other than the recommended ones could result in a lowering of safety and/or in a reduction in the
expected life of the cable. If a cable is intended to be used outside the recommended uses the cable
manufacturer should be consulted for advice.
In specific cases where guidance is not given, it is recommended that specific advice of the cable
manufacturer is sought.
In some countries, legislation may limit the use of certain cable types and define additional requirements for
cable installation practice.
Additional information on installation practice is given in HD 60364 and HD 384 series of specifications, and
national regulations/code practices.
1 Scope
This European Standard provides guidance to help installers, cabling designers and end users to understand
the characteristics of electric cables, with a rated voltage not exceeding 450/750 V (U /U) or equivalent d.c.
voltages, so that the cable can be selected, installed and operated in a safe way. It is applicable to those
cable types that are specified in EN 50525 (all parts).
The guidance given in this European Standard can also be applicable to low-voltage cables of a similar type to
those specified in EN 50525 but not specifically mentioned in those standards. In these cases, it is advisable
to seek additional advice from the cable manufacturer.
Legal or statutory requirements do take precedence over the guidance given in this document.
