SIST EN 60332-2-2:2005

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

Specifies the procedure for testing the resistance to vertical flame propagation for a single small vertical electrical insulated conductor or cable, or optical cable, under fire conditions. The apparatus is given in EN 60332-2-1. This standard gives the procedure for testing small optical fibre cables or a small insulated conductor or cable when the method specified in EN 60332-1-2 is not suitable because some small optical fibre cables may break or small conductors may melt during the application of the flame. The recommended range of application is for the testing of small single insulated conductors or cables of less than 0,5 mm² cross-section. NOTE 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.) Recommended requirements for performance are given in Annex A. 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 2-2: Essai de propagation verticale de la flamme sur conducteur ou câble isolé de petite section - Procédure pour une flamme de type à diffusion

Spécifie la méthode d'essai de résistance à la propagation verticale de la flamme sur un conducteur ou un câble électrique isolé de petite section, ou un câble à fibre optique, soumis au feu. L'appareillage est présenté dans la EN 60332-2-1. Cette norme fournit la procédure d'essai pour des petits câbles à fibres optiques ou pour conducteur ou câble électrique isolé de petite section dans les conditions rencontrées lorsque la méthode prescrite dans la EN 60332-1-2 n'est pas appropriée parce que les petits câbles à fibres optiques peuvent se rompre ou parce que les conducteurs de petite section peuvent fondre pendant l'application de la flamme. La plage d'application recommandée convient pour l'essai de conducteurs ou de câbles de section inférieure à 0,5 mm2. NOTE Étant donné qu'il ne suffit pas d'utiliser un conducteur 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 soit conforme aux conditions requises de performances 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 ). L'Annexe A donne les recommandations pour les prescriptions de performance. A le statut d'une publication groupée de sécurité conformément au Guide CEI 104.

EN 60332-2-2:2004 - Overview

EN 60332-2-2:2004 (CLC) specifies a test procedure for vertical flame propagation of a single small insulated wire or cable - including small optical fibre cables - using a diffusion flame. The standard is intended for samples that cannot be tested with the 1 kW pre-mixed flame method (EN/IEC 60332-1-2) because small optical fibres may break or metallic conductors may melt. The required apparatus is defined in EN/IEC 60332-2-1. This document is a group safety publication (IEC Guide 104) and includes recommended performance requirements in Annex A.

Key topics and technical requirements

• Scope: Single vertical insulated conductor or small optical cable under fire conditions; recommended for samples with conductor cross-section < 0.5 mm².
• Sample dimensions: Test piece length typically (600 ± 25) mm.
• Conditioning:
  • General: (23 ± 5) °C for ≥16 h at (50 ± 20) % RH.
  • Painted/lacquered finishes: additional pre‑conditioning at (60 ± 2) °C for 4 h before standard conditioning.
• Positioning and mounting:
  • Metallic-conductor samples fixed vertically with a loading arrangement (specified in the standard) so the specimen axis is centered in the screened test enclosure.
  • Optical fibre cables supported on horizontal supports as prescribed.
• Flame application:
  • Burner centre-line at 45° ± 2° to test piece; horizontal gap from burner orifice to specimen ~ (10 ± 1) mm.
  • Flame must envelope the specimen.
  • Standard flame application duration for metallic conductor samples: (20 ± 1) s. If conductor melts earlier (time T), the test is repeated for (T – 2) s and the repeat result used for assessment.
• Safety and evaluation:
  • Measures for fire, smoke and toxic product hazards (notably halogenated materials).
  • Test evaluation criteria and reporting procedures defined in Clause 6; Annex A gives recommended performance thresholds.
• Referenced standards: EN/IEC 60332-2-1 (apparatus), EN/IEC 60332-1-2 (premixed flame), IEC 60695-4 (terminology), IEC Guide 104.

Applications - who uses it and why

• Cable manufacturers use EN 60332-2-2 to validate small insulated conductors and micro optical cables for vertical flame resistance where other methods are unsuitable.
• Independent test laboratories apply the procedure for type testing, compliance assessment and certification.
• Specifiers, product safety engineers and certification bodies reference the standard in safety dossiers and regulatory compliance.
• Installers and system designers consult the standard to understand material behavior, but must note that passing this single‑sample test does not guarantee performance of cable bundles or long vertical runs - see EN 60332-3 series for multi‑cable scenarios.

Related standards

• EN/IEC 60332-2-1 (apparatus for small-sample vertical test)
• EN/IEC 60332-1-2 (1 kW premixed flame procedure)
• EN/IEC 60332-3 series (tests for bundled/installed cables)

INTERNATIONAL ELECTROTECHNICAL COMMISSION ____________TESTS ON ELECTRIC AND OPTICAL FIBRE CABLES
UNDER FIRE CONDITIONS –Part 2-2: Test for vertical flame propagation
for a single small insulated wire or cable –
Procedure for diffusion flame 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, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60332-2
