6 Marking
Insert, after Subclause 6.2 a), the following new Note:
NOTE Some lampholders still show rated voltages higher than 500 V. This is an earlier way of expressing the
permissible pulse voltage via a rated voltage. For such lampholders, the creepage distances and clearances can
be found in IEC 60598-1.

Insert, at the end of 6.2, the following new text:
Lampholders complying with the electrical strength test for double or reinforced insulation and
having creepage distances and clearances equivalent to double or reinforced insulation offer
an adequate level of protection for the use in luminaries where they are accessible in normal
use. Such lampholders are addressed as lampholders for use in class II applications. This
information shall be indicated in the manufacturer’s catalogue or the like.
NOTE 3 Values for creepage distances and clearances as well as test voltages for the electrical strength test for
double or reinforced insulation are given in IEC 60598-1.
To achieve sufficient creepage distances and clearances to outer accessible surfaces,
additional attachments could be used. In some cases, these dimensions might be achieved
only after mounting the lampholder in the luminaire. Relevant information should be provided
in the manufacturer’s catalogue or the like.
