Tests on electric cables under fire conditions -- Part 3-21: Test for vertical flame spread of vertically-mounted bunched wires or cables - Category A F/R

Specifies methods of tests for the assessment of vertical fame spread of vertically-mounted bunched wires or cables, electrical or optical, under defned conditions.

Prüfungen an Kabeln und isolierten Leitungen im Brandfall -- Teil 3-21: Prüfung der vertikalen Flammenausbreitung von vertikal angeordneten Bündeln von Kabeln und isolierten Leitungen - Prüfart A F/R

Essais des câbles électriques soumis au feu -- Partie 3-21: Essai de propagation verticale de la flamme des fils ou câbles en nappes en position verticale - Catégorie A F/R

Spécifie méthode d'essai pour l'évaluation de la propagation verticale de la flamme des fils ou câbles, électriques ou optiques, disposés en nappes en position verticale, dans des conditions définies. L'essai est prévu pour des essais d'acceptation de type. Les exigences pour la sélection des câbles pour l'acceptation de type sont données. La propagation de la flamme est mesurée comme étant l'étendue de la partie endommagée de l'échantillon de câble. Cette procédure peut être utilisée pour démontrer l'aptitude du câble à limiter la propagation de la flamme. Couvre la catégorie A F/R et concerne uniquement les câbles d'énergie ayant au moins un conducteur de section supérieure à 35 mm2 installés sur l'échelle d'essai dans une configuration espacée sur la face avant et la face arrière afin d'obtenir un volume nominal total de matériau non métallique de 7 l/m d'échantillon d'essai. La durée d'application de la flamme est de 40 min. Cette méthode de montage est prévue pour les constructions de câbles spéciales utilisées dans des installations particulières lorsque cela est requis dans la spécification de câble. La catégorie A F/R n'est pas prévue pour une utilisation générale. Donne aussi une recommandation pour la prescription de performance. A le statut d'une publication groupée de sécurité conformément au Guide 104 de la CEI.

TESTS ON ELECTRIC CABLES UNDER FIRE CONDITIONS –
Part 3-21: Test for vertical flame spread of vertically-mounted
bunched wires or cables – Category A F/R
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, the IEC publishes International Standards. Their preparation is
entrusted to technical committees; any IEC National Committee interested in the subject dealt with may
participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization
for Standardization (ISO) in accordance with conditions determined by agreement between the two
organizations.
2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60332-3-21 has been prepared by IEC technical committee 20:
Electric cables.
It has the status of a group safety publication in accordance with IEC Guide 104.
IEC 60332-3-21 forms one of a series of publications dealing with tests on electric cables under
fire conditions; the series supersedes IEC 60332-3 published in 1992. The parts of the series
are described in the introduction.
All pre-existing categories of test are retained and updated. A new category (category D) has
been added to cater for testing at very low non-metallic volumes.
The text of this standard is based on the following documents:
FDIS Report on voting
20/403/FDIS 20/427/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.
