Foreword
HD 21 was originally adopted by CENELEC on 9 July 1975.
Edition 2 of HD 21 was implemented on 1 January 1984 and at that time, contained five parts.
Since 1984 new parts have been published and the original parts revised.
Part 14 has been developed from Vilamoura Notification BT(BE/NOT)5 and introduces a range of flexible
cords and cables equivalent to those in Clauses 4 and 5 of HD 21.5 but with halogen-free thermoplastic
insulation and sheath. Consequently, and in parallel, the general title of HD 21 has been amended to
cover cables with any type of thermoplastic insulation.
HD 21 now has the following parts:
HD 21.1 S4 General requirements
HD 21.2 S3 Test methods
HD 21.3 S3 Non-sheathed cables for fixed wiring
HD 21.4 S2 Sheathed cables for fixed wiring (reprint)
HD 21.5 S3 Flexible cables (cords)
HD 21.6 (Spare)
HD 21.7 S2 Single core non-sheathed cables for internal wiring for a conductor temperature
of 90 °C
HD 21.8 S2 Single core non-sheathed cables for decorative chains
HD 21.9 S2 Single core non-sheathed cables for installation at low temperatures
HD 21.10 S2 Extensible leads
HD 21.11 S1 Cables for luminaries
HD 21.12 S1 Heat-resistant flexible cables (cords)
HD 21.13 S1 Oil resistant PVC sheathed cables with two or more conductors
HD 21.14 S1 Flexible cables (cords), insulated and sheathed with halogen-free thermoplastic
compounds
This Harmonization Document was prepared by the Technical Committee CENELEC TC 20, Electric
cables.
The text of the draft was submitted to the formal vote and was approved by CENELEC as HD 21.14 S1
on 2003-05-01.
The following dates were fixed:
- latest date by which the existence of the HD
has to be announced at national level (doa) 2003-11-01
- latest date by which the HD has to be implemented
at national level by publication of a harmonized
national standard or by endorsement (dop) 2004-05-01
- latest date by which the national standards conflicting
with the HD have to be withdrawn (dow) 2006-05-01

1 Scope
This Part 14 details the particular specifications for flexible cables (cords) of rated voltage up to and
including 300/500 V, insulated and sheathed with halogen-free thermoplastic compound and having low
emission of smoke and corrosive gases when exposed to fire. These cables are intended for the
connection of domestic appliances to the fixed supply.
All cables shall comply with the appropriate requirements given in Part 1 of HD 21 and with the particular
requirements of this Part 14.
NOTE 1 The overall dimensions of cables in this part of HD 21 have been calculated in accordance with EN 60719.
NOTE 2 Low emission of smoke is checked in accordance with EN 50268-2. Low emission of corrosive gases is checked as part
of the check for absence of halogens (see Annex C).
