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 original parts amended.
This new edition of HD 21.10 provides a full updating as part of the regular maintenance
programme that covers all Parts of HD 21.
HD 21 now has the following parts:
HD 21.1 S3 - 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 luminaires
HD 21.12 S1 - Heat-resistant flexible cables (cords)
HD 21.13 S1 - Oil resistant PVC sheathed cables with two or more conductors
This Harmonization Document was prepared by the Technical Committee CENELEC TC 20,
Electric cables.
The text of the draft was submitted to the Unique Acceptance Procedure and was approved
by CENELEC as HD 21.10 S2 on 2001-07-01.
The following dates were fixed:
- latest date by which the existence of the HD
has to be announced at national level (doa) 2002-02-01
- latest date by which the HD has to be implemented
at national level by publication of a harmonized
national standard or by endorsement (dop) 2002-08-01
- latest date by which the national standards conflicting
with the HD have to be withdrawn (dow) 2003-08-01

1 Scope
This part (Part 10) of the HD details the particular specifications for polyvinyl chloride
insulated extensible leads.
All cables shall comply with the appropriate requirements given in Part 1 and the individual
types of cable shall each comply with the particular requirements of this part.
NOTE 1 The overall dimensions of the cables in this part of HD 21, for the pre-coiled state, have been
calculated in accordance with EN 60719.
NOTE 2 In order that this revision of Part 10 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.
2 Light PVC insulated and sheathed extensible leads
2.1 Code designation
H03VVH8-F for extensible leads derived from circular cords
H03VVH2H8-F for extensible leads derived from flat cords
2.2 Rated voltage
300/300 V
2.3 Construction: pre-coiling
2.3.1 Conductor
Number of conductors: 2 or 3.
The conductors shall be in accordance with the requirements of Class 5, given in HD 383.
2.3.2 Insulation
The insulation shall be polyvinyl chloride compound of Type TI 2 applied around each
conductor.
The insulation resistance shall be not less than the values given in Part 10, Table 1,
column 4.
2.3.3 Assembly of cores
Circular cords for H03VVH8-F: the cores shall be twisted together.
Flat cords for H03VVH2H8-F: the cores shall be laid parallel.
2.3.4 Sheath
The sheath shall be polyvinyl chloride compound of Type TM 2 applied around the cores.
The sheath may fill the spaces between the cores, thus forming a filling, but it shall not
adhere to the cores. The assembly of cores may be surrounded by a separator which shall
not adhere to the cores.

2.3.5 Overall dimensions
The mean overall diameter of circular cords and the mean overall dimensions of flat cords
shall be within the limits given in Part 10, Table 1, columns 2 and 3.
2.4 Construction: post-coiling
2.4.1 Configuration
The cables shall be coiled in the form of a helical lead and caused substantially to maintain
this form during use.
2.4.2 Dimensions
The thickness of insulation shall comply with the specified values given in Part 10, Table 1,
column 5. The requirements of 5.2.3 of Part 1 shall apply.
The thickness of sheath shall comply with the specified values given in Part 10, Table 1,
column 6. The requirements of 5.5.3 of Part 1 shall apply.
Slight deformation of the cords, created by the coil forming process, is acceptable provided
that the thickness of the insulation and sheath meet the requirements.
2.4.3 Marking
The original marking, if any, on the pre-coiled cord may be affected by the coiling process
but this is acceptable provided that traceability is not impaired. The inclusion of the common
marking (�HAR�) as part of any original marking is not to be taken as evidence that the
extensible lead complies with clause 2 of Part 10 of this HD.
The producer of the extensible lead, if different from the producer of the pre-coiled cord,
must apply an additional mark, as indication of origin, as required by 3.1.2 of Part 1 of
this HD.
