September 1997.
th
This 4 edition provides a full updating, including incorporation of amendments ratified during the

HD 22.16 S1 Water resistant polychloroprene or equivalent synthetic elastomer sheathed
cables
In order that this revision of Part 1 of HD 22 does not introduce unnecessary changes to long-
established clause numbers, the normative references (which would otherwise be inserted as clause 2)
are given in annex A.
The draft Harmonization Document was submitted to the Unique Acceptance Procedure and approved
by CENELEC as HD 22.1 S4 on 2002-09-01.

The following dates were fixed:

- latest date by which the existence of the HD
has to be announced at national level  (doa) 2003-03-01

- latest date by which the HD has to be implemented
at national level by publication of a harmonized
national standard or by endorsement  (dop) 2003-09-01

- latest date by which the national standards conflicting
with the HD have to be withdrawn  (dow) 2003-09-01

Annexes designated "normative" are part of the body of the standard.
Annexes designated "informative" are given for information only.
In this standard, annex A is normative and annex B is informative.

1 General
1.1 Scope
HD 22 applies to rigid and flexible cables, sheathed and unsheathed, and insulated with
cross-linked material, of rated voltages U /U up to and including 450/750V, used in
o
power installations.
NOTE  For some types of flexible cables, the term "cord" is used.

This Part 1 specifies the general requirements applicable to these cables.

The test methods specified are given in Part 2 of this Harmonization Document (HD), or
in the common test methods for cables given in EN 50265, EN 50266, EN 50267,
EN 50268 and EN 60811.
The particular types of cables are specified in Part 3 onwards of this HD, which are
hereafter referred to as "the particular specifications".

The code designations of these types of cables are in accordance with HD 361.

1.2 Object
The objects of this HD are to standardise cables and cords that are safe and reliable
when properly used, to state the characteristics and manufacturing requirements
directly or indirectly bearing on safety, and to specify methods for checking conformity
with those requirements.
1.3 Common marking
The common marking () signifies that the manufacturer has been assessed,
and his production is subjected to continuing surveillance in accordance with the
technical procedures, by a recognised national Approval Organisation, which is a
signatory to the "Agreement on the use of a Commonly Agreed Marking for Cables and
Cords complying with Harmonised Specifications."

Compliance with this HD may be certified by the application of the agreed technical
1)
procedures for granting the common marking , which are the recognised means of
ensuring that a manufacturer is competent and takes all reasonable care to produce
cables complying with this HD.

The common marking may be used, under these conditions, by manufacturers in
countries which have implemented this HD and in which the national Approval
Organisations are signatories to the Agreement.

NOTE  See annex B for guidance on national marking.

2 Definitions
2.1 Definitions relating to insulating and sheathing materials and their processing

2.1.1 cross-linking
the process of multiple intermolecular covalent bonding between polymer
chains obtained through a chemical process, with or without the contribution of
heat, or through a physical process such as irradiation

1)
These are given in Appendices 4 and 5 of the 'Agreement on the use of a Commonly Agreed Marking for Cables and Cords
complying with Harmonised Specifications'.

2.1.2 vulcanisation
a post-application treatment taking place after the insulation and/or sheath has
been applied in order to induce cross-linking of the rubber or synthetic
elastomer
NOTE  Vulcanisation is an historical term now largely limited to use with the longer-established
materials which did, and in some cases still do, use sulphur as the primary chemical agent of
cross-linking.
2.1.3 type of compound
the category in which a compound is placed according to its properties, and
determined by specific tests. The type designation is not directly related to the
composition of the compound

combination of materials suitably selected, proportioned, treated, and
vulcanised, of which the characteristic constituent is a rubber and/or synthetic
elastomer
2.1.5 polychloroprene compound or equivalent synthetic elastomer
a vulcanised compound in which the elastomer is polychloroprene (PCP) or
equivalent synthetic elastomer providing a compound with properties similar to
polychloroprene
2.1.6 chlorinated rubber compound
a vulcanised compound in which the characteristic constituent is a synthetic
chlorinated rubber, e.g. Polychloroprene (PCP), Chlorosulphonated
Polyethylene (CSP), Chlorinated Polyethylene (CPE), etc

2.1.7 ethylene-propylene rubber compound (EPR) or equivalent synthetic
elastomer
a cross-linked compound in which the elastomer is ethylene-propylene or
equivalent synthetic elastomer providing a compound with properties similar to
EPR
2.1.8 ethylene vinyl acetate rubber compound (EVA) or equivalent synthetic
elastomer
a cross-linked compound in which the elastomer is ethylene vinyl acetate or

2.1.9 polyolefin based cross-linked compound or equivalent synthetic
compound having a low level of emission of corrosive gases when
burned
a cross-linked compound in which the polymer is a polyolefin or equivalent
synthetic non-halogenated polymer providing a compound which, when
burned, has low emission of corrosive gases and is suitable for use in cables
which, when burned, have low emission of smoke

2.1.10 cross-linked polyvinyl chloride (XLPVC)
combinations of materials of which polyvinyl chloride is the characteristic
constituent, including adequate cross-linking agents, suitably selected,
proportioned and treated which when cross-linked, meet the requirements

a compound based on a poly-siloxane polymer which, when cross-linked,
meets the requirements given for the particular cable
