Foreword
This edition 4 of HD 21.1 has been prepared by the Technical Committee CENELEC TC 20,
Electric cables.
HD 21 was originally adopted by CENELEC on 9th July 1975.
Edition 2 of HD 21 was implemented on 1st January 1984. A third edition of Part 1 was published
in September 1997.
th
This 4 edition provides a full updating, including incorporation of amendments ratified during the
maintenance of Part 3 onwards of HD 21, and introduces other improvements.
HD 21.1 S4 is related to IEC 60227-1:1993, but is not directly equivalent.
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 (with A1 inclusive)
HD 21.9 S2 Single core non-sheathed cable for installation at low temperatures
HD 21.10 S2 Extensible leads
HD 21.11 S1 Cables for luminaires
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
In order that this revision of Part 1 of HD 21 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 text of the draft was submitted to the Unique Acceptance Procedure and was approved by
CENELEC as HD 21.1 S4 on 2002-09-01.
The following dates were fixed:
- latest date by which the existance of the HD (doa) 2003-03-01
has to be announced at national level
- latest date by which the HD has to be (dop) 2003-09-01
implemented at national level by publication of
a harmonized national standard or by
endorsement
- latest date by which the national standards (dow) 2003-09-01
conflicting with the HD have to be withdrawn
