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.

Prüfungen zur Beurteilung der Brandgefahr - Teil 7-1: Toxizität von Rauch und/oder Brandgasen - Allgemeiner Leitfaden

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
