Test methods specified are given EN 60228, EN 60229, EN 60332-1-2, EN 60811, EN 60885-3, HD 605 and HD 632.
Attention should be drawn to the fact that a significant number of sections include references to long term tests which are collected in HD 605.  These long-term tests are considered as necessary and reflect the best available knowledge for the existing cable design.  They are related to specific designs and different philosophies concerning adequate measures against the influence of water.  However, it is the firm intention to reduce this large number of different tests, but more experience should be gained before starting to rationalise this important matter.
The particular types of cables are specified in Parts 9 to 12.
NOTE   Parts 3, 4, 5, 6, 7 and 8  were withdrawn in HD 620 S2.

This document describes the procedure and rules for extended application of results of tests carried out according to the test methods described in EN 50399, EN 60332 1 2 and EN 61034 2.
The EXAP rules described apply to EN 50399 test results used for classification according to EN 13501 6 in classes B2ca, Cca and Dca, additional smoke production classes s1, s2 and s3 and flaming droplets/particles, to EN 60332 1 2 test results used for classification in classes B2ca, Cca, Dca and Eca and to EN 61034 2 test results used for classification in classes s1a and s1b.
No EXAP procedure and rules have been developed in respect to the results of tests carried out according to the test method described in EN 60754 2. As the parameters (pH and conductivity) for each cable in a family are determined based upon calculation using material test results, this is considered as a matter of direct application. Material test results taken from any one sample of finished cable from a family are sufficient to calculate the parameters for each cable in the family.
Cables with a diameter of 5,0 mm or less are expected to be tested as bundles according to EN 50399. Cables with a diameter of less than or equal to 5,0 mm are included in the specific and general EXAP rules for single core unsheathed power cables only. The rules apply to circular and non-circular cables provided that they fall within the scope of the relevant test method.
A specific EXAP rule has been developed for any of the types of electric cable families as defined in this document. A general EXAP rule has been developed for all electric cable families unless otherwise stated elsewhere in this document.
NOTE 1    Multicore power cables are sometimes referred to as control cables with a rated voltage but for the purposes of this document are considered as power cables. For multipair, multitriple and multiquad control cables, either the general EXAP rule or the specific EXAP rule for power cables or the specific EXAP rule for communication cables can be applied.
The use of the specific EXAP rule gives benefit in the lower number of cables to be tested for a range of cable constructions (product family).
An EXAP is only possible when cables belong to a family as defined in this document.
NOTE 2   For the purposes of this document, the term "electric cables" also covers optical fibre cables.

This European Standard gives the general requirements for rigid and flexible energy cables of rated voltages U0/U up to and including 450/750 V AC, used in power installations and with domestic and industrial appliances and equipment.
NOTE 1   For some types of flexible cables, the term "cord" is used.
NOTE 2   Rated voltages are given by reference to alternating current systems. Use of the cables in direct current systems is permitted.
NOTE 3   National regulations may prescribe additional performance requirements for cables that are not given in the particular requirements. For example for buildings with high levels of public access, additional fire performance requirements may be applicable, The test methods for checking conformity with the requirements are given in other standards (see Introduction). The particular types of cables are specified in EN 50525-2 (series) and EN 50525-3 (series). The individual parts within those two series are collectively referred to hereafter as "the particular specifications". Only the sizes (conductor class, cross-sectional area), number of cores, other constructional features and rated voltages given in the particular specification apply to the individual cable type. The code designations of these types of cables are in accordance with HD 361.

This document specifies the apparatus and methods of test for the assessment of vertical flame spread, heat release, smoke production and occurrence of flaming droplets/particles of vertically mounted electric cables under defined conditions.
NOTE   For the purpose of this document, the term “electric cable” covers all power, control and communication cables, including optical fibre cables and hybrid cables used for the conveyance of energy and/or signals.
This document details the apparatus for the fire propagation testing and the arrangement and calibration of the instrumentation to be installed to measure the heat release and the smoke production during the test. The combustion gases are collected in a hood above the test chamber and conveyed through an exhaust system, which allows the measurement of heat release rate and smoke production. Test procedures to be used for type approval testing for classification of cables in classes [2, 7] B1ca, B2ca, Cca and Dca are given. Cable installation on the test ladder and the volume of air passing through the chamber are in accordance with the Commission Decision 2006/751/EC [6], which is reflected in the requirements of this document.

This document contains the requirements for accessories that are for use with covered conductors, see EN 50397 1. They are for applications in overhead lines with rated voltages U above 1 kV a.c. and not exceeding 36 kV a.c.
NOTE   This document describes the requirements and tests only for the accessories installed on the covered conductor itself.

This part of EN 50397 provides general recommendations for the selection, storage, transportation and installation of the covered conductors and the related accessories specified in EN 50397 1 and EN 50397 2, unless otherwise specified. Safety regulations and environmental regulations as well as rules for installation and mechanical design are not considered in this Guide to use, as they are covered by relevant national regulations and laws. Relevant national regulations are not considered in this guide, but it is advised that they are always consulted as appropriate.
NOTE   The term 'national regulations' is used throughout this guide. It can include specific safety regulations, rules of installation and other relevant instructions which, depending upon the particular country or district, can exist in a legislative (mandatory) form, or as a non-mandatory code of practice. In addition, certain specific utilities can have their own safety practices.
It is assumed that the design of installations, the purchase and installation of covered conductors and of the related accessories specified in this document are entrusted to suitably skilled and competent people. In case of doubt as to the suitability of covered conductors and the related accessories for a particular use, further specific information is expected to be obtained from the manufacturer.

IEC 60840:2011 is available as IEC 60840:2011 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60840:2011 specifies test methods and requirements for power cable systems, cables alone and accessories alone, for fixed installations     and for  rated voltages above 30 kV (U_m = 36 kV) up to   and including 150 kV (U_m = 170 kV). The requirements apply to single-core cables and to individually screened three-core cables and to their accessories for usual conditions of installation          and operation, but not to special  cables and their accessories,  such as submarine cables, for which modifications to the standard tests may be necessary or special test    conditions may  need to be   devised. This standard does not cover transition joints between cables with extruded insulation and paper insulated cables. The significant technical change with respect to the previous edition is     as follows:
- introduction of a prequalification test procedure for cables with high electrical stresses and tested as a cable system including accessories.
NOTE: For a more detailed history of events leading up to this fourth edition, see the Introduction.

NEW!IEC 60332-3-22:2018 is available as IEC 60332-3-22:2018 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60332-3-22:2018 covers category A for methods of test for the assessment of vertical flame spread of vertically mounted bunched wires or cables, electrical or optical, under defined conditions. This document relates to cables installed on the test ladder to achieve a nominal total volume of non-metallic material of 7 l/m of test sample. The flame application time is 40 min. The method of mounting uses the front of the ladder, a standard or wide ladder being used for cables having a conductor cross-section greater than 35 mm2 according to the number of test pieces required, and a standard ladder for conductor cross-sections 35 mm2 and smaller. The category is intended for general use where high volumes of non-metallic material are required to be evaluated. The test is intended for type approval testing. The requirements for the selection of cables for testing are given in Annex A. The flame spread is measured as the extent of damage of the cable sample. This procedure can be used to demonstrate the cable’s ability to limit flame spread. A recommended performance requirement is given in Annex B. This second edition cancels and replaces the first edition published in 2000 and Amendment 1:2008. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) adjustments have been made to the title, and elsewhere, to emphasise the standard is applicable to optical fibre cables as well as metallic conductor types;
b) details of the way in which cables are mounted on the ladder have been better defined in order to improve repeatability and reproducibility.
It has the status of a group safety publication in accordance with IEC Guide 104.
