3.14
Replace existing definition 3.14 with the following new definition:
self-recovering conduit
pliable conduit which deforms when a transverse force is applied for a short time and which,
after removal of this force, returns close to its original shape after a defined period
5.9
Delete this subclause.
7.1.1
Replace the existing text of Subclause 7.1.1 with the following new text:
The conduit or smallest supplied package shall also be marked with the classification code, in
accordance with Annex A, and shall include at least the first four digits.
Add, after Subclause 7.1.1, the following new subclause:
7.1.1.1
Self-recovering conduits shall also be marked on the conduit or smallest supplied package
with the classification code, in accordance with Annex A, and shall include at least the first
five digits.
Compliance is checked by inspection.
7.3
Add, after the first paragraph, the following new paragraph:
Flame propagating conduits shall also be marked with the following symbol:
– along its entire length at intervals of preferably 1 m but not longer than 3 m with each
length being marked at least once, and
– when the packaging of the smallest supplied package prevents the marking on the conduit
being seen, the symbol shall be marked on the packaging or by means of a label
IEC 60417-6180:2013-01
7.6

Compliance is checked by inspection, using normal or corrected vision, without additional
magnification and by rubbing the marking for 15 s with a piece of cotton cloth soaked with
water and again for 15 s with a piece of cotton cloth soaked with n-hexane 95 % .
When using the liquid specified for the test, precautions as stated in the relative material
safety datasheet provided by the chemical supplier shall be taken to safeguard the laboratory
technicians.
Laser marking directly on the product and marking made by moulding, pressing or engraving
are not subjected to this test.
The marking surface to be tested shall be dried before rubbing the marking with n-hexane
95 % solvent.
Rubbing shall commence immediately after soaking the piece of cotton, applying a
compression force of (5 ± 1) N at a rate of about one cycle per second (a cycle comprising a
forward and backward movement along the length of the marking). For markings longer than
20 mm, rubbing can be limited to a part of the marking, over a path of at least 20 mm length.
The compression force is applied by means of a test piston which is wrapped with cotton
comprising of cotton wool covered by a piece of cotton medical gauze.
The test piston shall have the dimensions given in Figure 9 and shall be made of an elastic
material which is inert against the test liquids and has a Shore-A hardness of 47 ± 5 (for
example synthetic rubber).
When it is not possible to carry out the test on the specimens due to the shape/size of the
product, a suitable piece having the same characteristics as the product can be submitted to
the test.
After the test, the marking shall be legible.
10.3.1
Replace the existing second paragraph of Subclause 10.3.1 with the following new text:
Conduits are tested without fittings. Fittings are tested with a short length of conduit
assembled to them as in normal use.
Delete the note.
10.3.2
Replace the existing text of Subclause 10.3.2 with the following new text:
The test apparatus is placed on a firm flat surface.
The samples are conditioned for 2 h in a cold chamber at the temperature specified in Table 1
with a tolerance of ± 2 °C corresponding to the declared classification. The samples are
removed from the cold chamber and placed on a flat steel surface as shown in Figure 2.
The hammer shall fall once on each sample. The time between the removal of the sample
from the cold chamber and the completion of the impact test shall not be greater than 10 s.
The mass of the hammer and the fall height are specified in Table 5.

The test is made on what is likely to be the weakest part of the conduit or fitting except that it
is not applied within 5 mm of any conduit entry of the fitting. Conduit test samples shall be
tested at the centre of their length.
11.3.1.2
Replace the existing first paragraph of Subclause 11.3.1.2 with the following new text:
After 24 h ± 15 min, an a.c. voltage of substantially sine wave form and having a frequency
between 45 Hz and 65 Hz is applied across the two electrodes. The voltage is then gradually
increased from 1 000 V to 2 000 V a.c. Once the maximum voltage has been reached it shall
+5
be maintained for a period of 60 s.
Replace the last paragraph with the following new text:
The samples shall be considered to have adequate electrical insulating strength if a 100 mA
trip device, incorporated into the circuit, does not trip during the test.
13.1.3 Spread of fire
Add, at the end of Subclause 13.1.3, the following new Note:
NOTE In accordance with 422.3.4 of IEC 60364-4-42:2010 and Annex F of IEC 60364-5-52:2009, flame
propagating conduits are not suitable for use in buildings, unless embedded in non-combustible material, such as
concrete.
14.2.2.2
Replace the existing first paragraph of Subclause 14.2.2.2 with the following new paragraph:
Medium protection conduit and conduit fittings shall be cleaned with a piece of wadding
soaked in white spirit.
