FOREWORD
This amendment has been prepared by subcommittee 34B: Lamp caps and holders, of IEC
technical committee 34: Lamps and related equipment.
The text of this amendment is based on the following documents:
FDIS Report on voting
34B/1587/FDIS 34B/1599/RVD
Full information on the voting for the approval of this amendment can be found in the report
on voting indicated in the above table.
The committee has decided that the contents of this amendment and the base publication will
remain unchanged until the stability date indicated on the IEC web site under
"http://webstore.iec.ch" in the data related to the specific publication. At this date, the
publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
The contents of the corrigendum of December 2012 have been included in this copy.
_____________
1 General
1.1 Scope
Replace, in the penultimate sentence, B15 by B15d.
Replace, in the last sentence, B22 by B22d.
2 Terms and definitions
Add the following two new definitions:
2.25
enclosed reinforced insulated lampholder
lampholder for building-in, so designed that on its own it fulfils the requirements for double or
reinforced insulated parts in class II applications
2.26
partly reinforced insulated lampholder
lampholder for building-in, so designed that some parts of the lampholder require additional
means to fulfil the requirements with regard to double or reinforced insulation
NOTE  In some cases, the dimensions might be achieved only after mounting into the luminaire.

5 Standard ratings
5.2 Standard rated currents
Replace, in the first dashed item, B15 by B15d.
Replace, in the second dashed item, B22 by B22d.
6 Classification
Replace the existing Subclause 6.5 by the following:
6.5 According to protection against electric shock:
− unenclosed lampholders;
− enclosed lampholders;
− independent lampholders;
− partly reinforced insulated lampholders;
− enclosed reinforced insulated lampholders.
NOTE Where a lampholder is used with a working voltage of 50 % or less of its maximum rating, it may be
regarded as equivalent to a reinforced insulated lampholder.
7 Marking
Replace, in Subclause 7.1, the third paragraph (“Lampholders complying with the…”), the
following note and the last paragraph by the following new text:
Enclosed reinforced insulated lampholders offer an adequate level of protection for use in
luminaires where they are accessible in normal use. This information shall be indicated in the
manufacturer’s catalogue ore the like.
For partly reinforced insulated lampholders, sufficient creepage distances and clearances to
outer accessible surfaces will require additional protection to some parts of the lampholder by
the luminaire design or by use of additional attachment(s) or cover(s). This information shall
be indicated in the manufacturer’s catalogue or the like.
th
Replace the note of the 6 dashed item in Subclause 7.1 with the following new note:
NOTE Available technical documentation of the manufacturer like printed catalogues or online catalogues should
allow a clear identification of a lampholder either by a unique catalogue number or by an identifying reference on
the holder, specifying the essential characteristic features and the basic design of the product supplemented by a
clear description. Variations of the basic design like for example different cable length, fixing means, colours etc.,
which do not affect safety or performance of the lampholder, may be disregarded in the type reference marked on
the product. Variations included in the type testing procedure are listed in the corresponding test reports.

8 Dimensions
Replace, in the first dashed item of Subclause 8.2, B15 by B15d.
Replace, in the second dashed item of Subclause 8.2, B22 by B22d.
Table 2 – Minimum dimensions of pillar type terminals
Replace, in the first column of the table, B15 by B15d and B22 by B22d.
12 Construction
Replace, in the second sentence of Subclause 12.1, B15 by B15d and B22 by B22d.
14 Moisture resistance, insulation resistance and electrical strength
th
Replace, in 14.3, the 8 paragraph (“Immediately after the insulation resistance…”) by the
following new paragraph:
Immediately after the insulation resistance test, an a. c. voltage of substantially sine wave
form, with a frequency of 50 Hz or 60 Hz and with an r. m. s. value of (2 U + 1 000) V (where
U is the rated voltage) is applied for 1 min between the points prescribed. For enclosed and
unenclosed reinforced insulated lampholders, the test voltage shall be determined from
Table 10.2 of IEC 60598-1. Additionally, for switched lampholders, this voltage shall be
applied between live parts of different polarity and other metal parts with the switch both
closed and open.
Table 6 – Maximum deformation values
Replace, in the first column of the table, B15 by B15d and B22 by B22d.
Table 8 – Minimum distances for a. c. (50/60 Hz) sinusoidal voltages – Impulse
withstand category II
Replace the existing table by the following:

b In the case of creepage distances to parts not energized or not intended to be earthed, where no tracking can
occur, the values specified for material with PTI  600 apply for all materials (irrespective of the real PTI).
For creepage distances subjected to working voltages of less than 60 s duration, the values specified for
materials with PTI  600 apply for all materials.
c For creepage distances not liable to contamination by dust or moisture, the values specified for material with
PTI  600 apply (independently of the real PTI).
d For B15d lampholders the clearance is reduced to 1,4 mm.
e These values take account of possible unevenness of the mounting surface.
