Common test methods for cables under fire conditions - Heat release and smoke production measurement on cables during flame spread test - Test apparatus, procedures, results

This amendment consists of a modification to Subclauses 6.4 and 6.5 to cover the testing of non circular cables and to improve the repeatability and reproducibility of testing of bundles (for cables with a diameter less than or equal to 5,0 mm) and some further improvements based on wider operating experience.

1 Modification to Clause 2, Normative references
Replace the whole reference to EN 60332-3-10 with the following one:
"EN 60332-3-10:2009, Tests on electric and optical fibre cables under fire conditions – Part 3-10:
Test for vertical flame spread of vertically-mounted bunched wires or cables – Apparatus
(IEC 60332-3-10:2000)".
2 Modification to 6.4, Determination of the number of test pieces
Replace the whole subclause with the following one:
"
6.4 Determination of the number of test pieces
6.4.1 General
The following formulae shall be used to determine the number of test pieces (N) for the test.
6.4.2 Circular cables with a diameter greater than or equal to 20,0 mm
The number of test pieces, N, is given by:
 
300+ 20
 
N= int (1)
 
d + 20
c
 

where
d is the measured diameter of the cable (in millimetres, measured to one
c
decimal place of a millimetre and rounded to the nearest millimetre according
to Annex J);
int function the integer part of the result (i.e. the value rounded down).
6.4.3 Circular cables with a diameter greater than 5,0 mm but less than 20,0 mm
The number of test pieces, N, is given by
 
300+d
c
 
N= int (2)
 
2d
 c 

where
d is the measured diameter of the cable (in millimetres, measured to one
c
decimal place of a millimetre and rounded to the nearest millimetre according
to Annex J);
int function the integer part of the result (i.e. the value rounded down).

6.4.4 Circular cables with a diameter less than or equal to 5,0 mm
A number of approximately 10 mm diameter bundles (N ) shall be mounted where:
bu
300+10
 
N = int =15 (3)
 
bu

 

Thus 15 bundles shall be mounted.
The number of test pieces in each bundle (n) is:
100
 
n= int (4)

 
d
 c 

where
d is the measured diameter of the cable (in millimetres, measured to two
c
decimal places of a millimetre and rounded to one decimal place according to
Annex J);
int function the integer part of the result (i.e. the value rounded down).
The total number of test pieces (N) will thus be:
N=n×15 (5)
6.4.5 Non-circular cables with a major axis dimension greater than or equal to 20,0 mm,
a minor axis dimension greater than 4,0 mm and a major to minor axis ratio less
than or equal to 5
