How to read a HAR: HD 361 harmonised designation (CENELEC) cable code

Fire behaviour (EU CPR)

Halogen-free compound (Z1). Under the CPR this shows in the additional classes: acidity a1 to a3 (EN 60754-2) and smoke s1 to s3 (EN 50399; s1a and s1b add the 3 m cube test EN 61034-2). The main class, Aca to Fca, depends on the whole construction.
Typically targeted, as declared by makers for this kind of construction in the examples this site checked (not the class of this cable):
- B2ca-s1,d0,a1 1-CXKH-R-J, Kablo Vrchlabí
- Cca-s1b,d1,a1 FG16(O)M16, Nexans (La Triveneta Cavi)
- B2ca-s1a,d1,a1 FG18(O)M16, Nexans (La Triveneta Cavi)
- Dca FXQJ, Nexans Norway
- Cca-s1,d1,a1 H07Z1-K, Nexans Spain
- B2ca AXQJ-RMF, Prysmian Sweden (12/20 kV)
- Cca-s1b,d1,a1 RZ1FZ1-K (AS), Top Cable
- Cca-s1a,d1,a1 RZ1-K (AS), Top Cable (B2ca-s1a,d1,a1 for some sizes)

A CPR class is declared by the maker in its Declaration of Performance and printed on the sheath (EN 50575 cl 7). This decoder does not assign one. What the CPR classes mean →

H05Z1-K as the cable designer builds it, 1x1 300/500 V

Overall diameter 2.5 mm, about 10 kg/km. Nominal values from the standard's tables for this size, computed, not a maker's data.

H05Z1-K on a drum

The smallest drum that passes every check, for 2.5 mm and about 10 kg/km as the cable designer builds it. Drums as their makers print them; lengths are estimates within a few per cent of the cable makers' own tables: whole layers, wound diameter 1.05 × OD, 50 mm freeboard under the flange rim.

Length	Drum size (its makers)	Layers	Gross weight
500 m	KTG 3 (390 mm flange), plastic KTG drums (Europe), KTG	7 of 31	7 kg
1,000 m	KTG 3 (390 mm flange), plastic KTG drums (Europe), KTG	13 of 31	12 kg

Barrel at least 12 × OD = 30 mm for a cable of this kind (Flexible cable (class 5 or 6 conductor)): KTG table, the cable's datasheet wins. A load rating is the drum maker's own.
