Tests on electric and optical fibre cables under fire conditions -- Part 1-2: Test for vertical flame propagation for a single insulated wire or cable - Procedure for 1 kW pre-mixed flame

Specifies the procedure for testing the resistance to vertical flame propagation for a single vertical electrical insulated conductor or cable, or optical fibre cable, under fire conditions. The apparatus is given in EN 60332-1-1. NOTE 1 Testing to EN 60332-1-2 may be performed simultaneously with that to EN 60332-1-3 if required. Recommended requirements for performance are given in Annex A. EN 60332-1-2 specifies the use of a 1 kW pre-mixed flame and is for general use, except that the procedure specified may not be suitable for the testing of small single insulated conductors or cables of less than 0,5 mm² total cross-section because the conductor melts before the test is completed, or for the testing of small optical fibre cables because the cable is broken before the test is completed. In these cases, the procedure given in EN 60332-2-2 is recommended. NOTE 2 Since the use of insulated conductor or cable which retards flame propagation and complies with the recommended requirements of this standard is not sufficient by itself to prevent propagation of fire under all conditions of installation, it is recommended that wherever the risk of propagation is high, for example in long vertical runs of bunches of cables, special installation precautions should also be taken. It cannot be assumed that because the sample of cable complies with the performance requirements recommended in this standard, that a bunch of cables will behave in a similar manner. (See EN 60332-3 series.) Has the status of a group safety publication in accordance with IEC Guide 104.

Essais des câbles électriques et à fibres optiques soumis au feu -- Partie 1-2: Essai de propagation verticale de la flamme sur conducteur ou câble isolé - Procédure pour flamme à prémélange de 1kW

Spécifie la méthode d'essai de résistance à la propagation verticale de la flamme sur conducteur ou câble électrique isolé ou sur câble à fibres optiques, soumis au feu. L'appareillage d'essai est décrit dans la EN 60332-1-1. NOTE 1 L'essai de la EN 60332-1-2 peut être réalisé simultanément avec celui de la EN 60332-1-3 si demandé. L'Annexe A donne les recommandations pour les prescriptions de performance. La EN 60332-1-2 donne des précisions sur l'emploi d'une flamme de type à prémélange de 1 kW et est destinée à un usage général. Cependant, la procédure spécifiée peut ne pas convenir pour l'essai sur conducteur ou câble isolé de section totale inférieure à 0,5 mm2, car l'âme peut fondre avant la fin de l'essai, ou bien encore pour l'essai de petits câbles à fibres optiques parce que le câble est rompu avant la fin de l'essai. Dans ces cas, la procédure indiquée dans la EN 60332-2-2 est recommandée. NOTE 2 Étant donné qu'il ne suffit pas d'utiliser un conducteur isolé ou un câble retardant la propagation de la flamme et correspondant aux exigences de la présente norme pour empêcher la propagation du feu dans n'importe quelles conditions d'installation, il est recommandé de prendre également des précautions spéciales d'installation chaque fois que le risque de propagation du feu est grand, par exemple dans les cas de grandes longueurs de faisceaux de câbles verticaux. Le fait qu'un échantillon de câble est conforme aux conditions requises de comportement figurant dans la présente norme n'implique pas qu'un faisceau de câble du même type se comportera nécessairement de façon identique. (Voir la série EN 60332-3 ). A le statut d'une publication groupée de sécurité conformément au Guide CEI 104.

Preskusi na električnih kablih in kablih iz optičnih vlaken v požarnih razmerah – 1-2. del: Preskus navpičnega širjenja ognja po posamezni izolirani žici ali kablu – Postopek za predmešani plamen 1 kW

Ta del standarda IEC 60332 določa postopek preskušanja odpornosti proti širjenju požara v navpični smeri za enojni navpični električni izolirani vodnik/kabel ali kabel iz optičnih vlaken v primeru požara. Aparat je določen v standardu IEC 60332-1-1.
OPOMBA 1: Po potrebi se lahko preskušanje v skladu z določili standarda IEC 60332-1-2 izvaja hkrati s preskušanjem v skladu z določili standarda IEC 60332-1-3.
Priporočene zahteve glede lastnosti so navedene v dodatku A. IEC 60332-1-2 določa uporabo predmešanega plamena 1 kW in je namenjen za splošno uporabo, vendar predpisani postopek morda ne bo primeren za preskušanje posameznih tankih izoliranih vodnikov ali kablov s skupnim presekom manj kot 0,5 mm2, ker se vodnik stali, preden je preskus dokončan, ali za preskušanje tankih kablov iz optičnih vlaken, ker se kabel zlomi, preden je preskus dokončan. V teh primerih se priporoča uporaba postopka, navedenega v standardu IEC 60332-2-2.
OPOMBA 2: Ker zgolj uporaba izoliranega vodnika ali kabla, ki zavira širjenje požara in izpolnjuje priporočene zahteve tega standarda, ne zadostuje za preprečitev širjenja požara pri vseh pogojih napeljave, je treba v primeru visoke stopnje nevarnosti širjenja požara (npr. pri dolgih navpično speljanih snopih kablov) izvesti posebne previdnostne ukrepe glede napeljave. Predpostavka, da bodo snopi kablov delovali na podoben način, zato ker vzorec kabla izpolnjuje zahteve glede lastnosti, priporočene v tem standardu, ni nujno pravilna.

Overview

EN 60332-1-2:2004 (CLC) - also published as IEC 60332-1-2:2004 - defines a laboratory procedure for assessing vertical flame propagation of a single insulated electrical conductor, cable, or optical fibre cable using a 1 kW pre‑mixed flame. The standard specifies sample preparation, conditioning, positioning, flame application and test duration. The required test apparatus is defined in EN 60332-1-1. EN 60332-1-2 is a group safety publication (IEC Guide 104) and gives recommended performance criteria in Annex A.

Key topics and technical requirements

• Scope: Test of a single vertical insulated conductor or cable (electrical or optical) to evaluate resistance to vertical flame propagation under fire conditions.
• Test apparatus: Use the apparatus specified in EN 60332-1-1 (metal screen, supports, burner).
• Sample: Single insulated conductor/cable, nominal length (600 ± 25) mm.
• Conditioning: Ambient conditioning at (23 ± 5) °C and (50 ± 20) % RH for at least 16 h. Painted or lacquered samples require a 4 h preliminary 60 °C treatment.
• Positioning: Vertical specimen centrally mounted; 550 ± 5 mm between supports; bottom ≈ 50 mm from base of the screen.
• Flame application: Single burner with inner blue cone impinging on the specimen at (475 ± 5) mm from the upper support and an angle of 45° ± 2°. Safety precautions for smoke and toxic products are required.
• Test duration: Flame is applied continuously for a time based on specimen overall diameter (examples from the standard):
  • D ≤ 25 mm: 60 s (or 120 s in some cases)
  • 25 < D ≤ 50 mm: 240 s
  • 50 < D ≤ 75 mm: 480 s
    (The standard gives the full table and rules for equivalent diameter for non‑circular cables.)
• Limitations: Not suitable for very small conductors (< 0.5 mm² total cross‑section) or tiny optical fibre cables where melting or mechanical breakage occurs - for those, EN 60332-2-2 is recommended. The standard cautions that passing the single‑cable test does not guarantee the same behaviour for bundles or installed cable runs (see EN 60332-3 series).

Applications and users

• Cable manufacturers - design verification and flame‑retardant material selection.
• Independent test laboratories - routine compliance testing and type‑approval.
• Specifiers / procurement - define fire‑performance requirements in tenders and product specs.
• Safety engineers / installers - assess fire risk for vertical runs and inform installation precautions.
• Regulatory bodies / certification - harmonized method for evaluating flame propagation in cables.

Related standards

• EN 60332-1-1 (apparatus for vertical flame test)
• EN 60332-1-3 (flaming droplets/particles)

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of 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, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). 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. 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 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 IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, prope
