Fire hazard testing - Part 7-1: Toxicity of fire effluent - General guidance

Provides guidance on the factors which affect the toxic hazard from fires involving electrotechnical products, and provides information on the methodologies recommended by ISO TC 92 (SC 3) for estimating and reducing toxic hazard from fires, as expressed in ISO/TR 9122 (Parts 1 to 6), ISO 13344 and ISO/TS 13571. There is no single test to realistically assess toxic hazard in fires. Small-scale toxic potency tests are not capable on their own of assessing fire hazard. Current toxicity tests attempt to measure the toxic potency of a laboratory generated fire effluent. Toxic potency should not be confused with toxic hazard. Although the structure of this standard remains essentially the same, the main changes with respect to the previous edition are listed below: - Introduction: an explanation concerning the publication of EN 60695-7-50, a small-scale toxicity test method, reference to EN 60695-7-51 which covers the calculation and interpretation of test results, an explanation of the alignment with ISO/TC 92 Fire safety. - The expansion of the scope further clarifies the subject matter and alignment with ISO/TC 92, in particular ISO 13344 and ISO/TS 13571. - Formulae are given for the calculation of the fraction of the incapacitating dose for each of the asphyxiants, carbon monoxide and hydrogen cyanide. - Volume fractions that are expected to cause incapacitation (F values) are given for some of the more important irritants. - The definitions have been greatly expanded and updated. - The subclause on factors determining toxic hazard has been expanded. - New subclauses include general aspects of small-scale test methods, evaluation of test methods and the relevance of toxic hazard data to hazard assessment. - A flowchart has been added to outline the stages to be followed for test method assessment. Has the status of a basic safety publication in accordance with IEC Guide 104.

Essais relatifs aux risques du feu - Partie 7-1: Toxicité des effluents du feu - Lignes directrices générales

Fournit des lignes directrices sur les facteurs qui affectent le danger toxique des feux impliquant des produits électrotechniques et fournit des informations sur les méthodologies recommandées par le TC 92 (SC 3) de l'ISO concernant l'estimation et la réduction du risque toxique des incendies, comme exprimé dans les Parties 1 à 6 de l'ISO/TR 9122, dans l'ISO 13344 et dans l'ISO/TS 13571. Il n'y a pas d'essai unique pour évaluer de façon réaliste le risque toxique des incendies. Les essais de puissance toxique à petite échelle ne sont pas capables en eux-mêmes d'évaluer le risque de feu. Les essais de toxicité actuels tentent de mesurer la puissance toxique d'un effluent du feu généré en laboratoire. Il convient de ne pas confondre puissance toxique et risque toxique. Bien que la structure de la présente norme demeure pratiquement inchangée, les modifications principales par rapport à l'édition précédente sont les suivantes : - Introduction : description des travaux récents relatifs à la publication de la EN 60695-7-50, méthode d'essai à la toxicité à petite échelle, référence à la EN 60695-7-51 qui concerne le calcul et l'interprétation des résultats d'essai, explications relatives à l'alignement sur les travaux du TC 92 de l'ISO, Sécurité au feu. - Extension du domaine d'application à fins de clarification et d'alignement sur les travaux du TC 92 de l'ISO, en particulier de l'ISO 13344 et de l'ISO/TS 13571. - Formules données pour le calcul de la fraction de la dose incapacitante pour chacun des agents asphyxiants, le monoxyde de carbone et l'acide cyanhydrique. - Fractions volumiques supposées causer l'incapacitation (valeurs F) données pour certains des irritants les plus importants. - Ajouts et mises à jour des définitions. - Développement du paragraphe qui concerne les facteurs déterminant le danger toxique. - Nouveaux paragraphes relatifs aux aspects généraux des méthodes d'essai à petite échelle et à l'évaluation des méthodes d'essai et à la pertinence des d

FIRE HAZARD TESTING –
Part 7-1: Toxicity of fire effluent –
General guidance
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 60695-7-1 has been prepared by IEC technical committee 89: Fire
hazard testing.
It has the status of a basic safety publication in accordance with IEC Guide 104.
This second edition cancels and replaces the first edition published in 1993. It constitutes a
technical revision.
