2 Normative references
Add the following new reference:
IEC 60811-203, Electric and optical fibre cables – Test methods for non-metallic materials –
Part 203: General tests – Measurement of overall dimensions
3 Terms and definitions
Replace the existing source of item 3.1 by the following new source:
[SOURCE: ISO 13943:2008, 1.489]
Replace the existing source of item 3.2 by the following new source:
[SOURCE: ISO 13943:2008, 4.38]
5.1 Sample
Replace the existing subclause by the following new subclause:
The test sample shall be a piece of single insulated conductor or cable (600 ± 25) mm long.
The test sample diameter shall be measured using the method given in IEC 60811-203. The
measurement shall be made at each of three places, separated by at least 100 mm.

© IEC 2015
The average of the three values obtained shall be rounded to obtain the overall diameter. If
the calculation gives 5 or more for the second decimal figure, raise the first to the next
number; thus, for example, 5,75 is rounded to 5,8. If the calculation gives 4 or less for the
second decimal figure, maintain the first number; thus, for example, 5,74 is rounded to 5,7.
The overall diameter obtained shall be used for the selection of the time for flame application.
5.3 Positioning of test piece
Replace the existing subclause by the following new subclause:
The test piece shall be straightened and secured to two horizontal supports by means of a
suitable size of copper wire, in a vertical position in the centre of the metal enclosure, as
described in IEC 60332-1-1, so that the distance between the bottom of the upper support and
the top of the lower support is (550 ± 5) mm. In addition, the test piece shall be positioned so
that the bottom of the specimen is approximately 50 mm from the base of the enclosure (see
Figure 1).
