6.1 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
Add the following new note to Subclause 7.1 below item “b) type reference”:
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.
Replace, in Subclause 7.2, the fourth paragraph (“Lampholders and starterholders
complying…”), the note and the fifth 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.
