4.3.1.5 Sheath

The cores shall be covered with a sheath.
a) For cables with a specified sheath thickness up to and including 2,4 mm:

1) sheath in a single layer, cross-linked elastomeric compound of type EM 2 to
EN 50363-2-1.

b) For cables with a specified sheath thickness greater than 2,4 mm:
1) sheath either in a single layer, cross-linked elastomeric compound of type EM 2 to

EN 50363-2-1;

2) or in two layers, with the inner layer made of one of the cross-linked elastomeric
compounds type EM 2 or EM 3 to EN 50363-2-1 and the outer layer of the crosslinked
elastomeric compound type EM 2 to EN 50363-2-1.

The sheath applied in a single layer or the inner layer of the sheath in two layers shall, for
cables with two to five cores, fill the spaces between the cores. Where a tape of suitable
material is applied around the core assembly (see NOTE 2 to 4.3.1.4) this requirement shall
not apply, provided that the finished cables shall not have any substantial cavity in the outer
interstices between the cores.

particular requirements of this Part.
Testing shall be in accordance with Table A.1, column 8.
NOTE For non-electrical tests on sheaths in two layers see EN 50525-1, 5.7.2.3, c).
The dimensions of the cables shall conform to Table B.2 for the relevant size.
The requirements to be met for the compatibility test shall be as given in Table C.1.

4.4 Heavy duty multicore cables – H07RN-F

4.4.1 Construction

4.4.1.1 Conductor

The conductor shall be class 5, according to EN 60228.

4.4.1.2 Sizes of cable

The sizes of cable shall be:
- 6, 7, 12, 18, 24 and 36 core – 1,5 mm2 and 2,5 mm2;
- 6, 7, 12 and 18 core – 4 mm2.
NOTE The number of cores given here is preferred. Other numbers of cores are permitted up to the maximum
number stated in the table for the given size of conductor, subject to agreement between the purchaser and
manufacturer. See also footnote c to Table B.3.

4.4.1.3 Insulation

The insulation shall be a cross-linked elastomeric compound, Type EI 4 to EN 50363-1
applied around each conductor.
The identification of each core shall be in accordance with Annex D of EN 50525-1.

4.4.1.4 Assembly

The cores shall be twisted together. A single core in the centre is not permitted. A protective
conductor, if any, shall be applied in the outer layer. A centre filler shall be used for cables
having 6, 7, 18, and 36 cores, and also for 19 cores when this non-preferred size is used.
NOTE 1 A centre filler may be used for other sizes.
NOTE 2 A tape may be applied around the core assembly before application of the sheath.

4.4.1.5 Sheath

The core assembly shall be covered with a sheath. The sheath shall be applied either in a
single layer, cross-linked elastomeric compound EM 2 to EN 50363-2-1, or in two layers, with
the inner layer made of one of the cross-linked elastomeric compounds EM 2 or EM 3 to
EN 50363-2-1 and the outer layer of cross-linked elastomeric compound EM 2 to
EN 50363-2-1.
The sheath in a single layer or the inner layer of the sheath in two layers shall fill the spaces
between the cores. Where a tape of suitable material is applied around the core assembly
(see NOTE 2 to 4.4.1.4) this requirement shall not apply, provided that the finished cables
shall not have any substantial cavity in the outer interstices between the cores.

4.4.1.6 Marking

The cable shall be marked with the CENELEC code H07RN-F. The marking shall comply with
Clause 6 of EN 50525-1.

4.4.2 Requirements

Each cable shall comply with the appropriate requirements given in EN 50525-1, and the
particular requirements of this Part.
Testing shall be in accordance with Table A.1, column 9.
NOTE For non-electrical tests on sheaths in two layers see EN 50525-1, 5.7.2.3, c).
The dimensions of the cables shall conform to Table B.3 for the relevant size.
The requirements to be met for the compatibility test shall be as given in Table C.1.

H07RN-F

H07RN-F is a harmonized, heavy duty, flexible and chloroprene sheathed cable.

The recommended use is varied; typically it is fitted in electrical equipment under that are under conditions of moderate mechanical stress.

H07RN-F is a multi-conductor up to 750V. Standard European cables and can be used for circuit-proofing and are valuable for short-to-ground proof installations. The jacket is made out of a rubberised neoprene and therefore is weather resistant. This makes H07RN-F rubber cable suitable for both indoor and outdoor use.

The H07RN-F rubber cable features heavily in electrical tools and industrial equipment such as circular saws and drills, transportable generators and motors, and other mechanical machines that are put under medium stress. H07RN-F is common, and is suitable for use with boilers, hand lamps and heating plates. It is also very useful when constructing temporary buildings, installations and residential barracks.
