Fire hazard testing - Part 7-2: Toxicity of fire effluent - Summary and relevance of test methods

Gives a brief summary of the test methods that are in common use in the assessment of lethal and sublethal acute toxic potency, and other toxicity tests. It includes special observations on their relevance to real fire scenarios and gives recommendations on their use. It advises which tests provide toxic potency data which is relevant to real fire scenarios, and which are suitable for use in fire hazard assessment and fire safety engineering. Has the status of a basic safety publication in accordance with IEC Guide 104.

Essais relatifs aux risques du feu - Partie 7-2: Toxicité des effluents du feu - Résumé et pertinence des méthodes d'essai

Fournit un bref résumé des méthodes d'essai qui sont d'un usage courant dans l'évaluation du potentiel toxique létal et pré-létal et autres essais de toxicité. Elle comprend des observations particulières sur leur pertinence par rapport aux scénarios d'incendies réels et donne des recommandations sur leur utilisation. Elle indique quels sont les essais fournissant des données de puissance toxique pertinentes pour les scénarios d'incendies réels, et quels sont ceux qui sont adaptés à l'utilisation dans l'évaluation des risques du feu et l'ingénierie de sécurité incendie. A le satut d'une publication fondamentale de sécurité conformément au Guide 104 de la CEI.

Preskušanje požarne ogroženosti - 7-2. del: Toksičnost dimnih plinov - Povzetek in relevantnost preskusnih metod

Ta del IEC 60695 podaja kratek povzetek preskusnih metod, ki so v splošni uporabi pri ocenjevanju akutne učinkovitosti strupa in drugih preskusov toksičnosti. Vključuje posebne ugotovitve glede njihove pomembnosti za realne požarne scenarije ter podaja priporočila za njihovo uporabo. Svetuje, kateri preskusi zagotavljajo podatke o učinkovitosti strupa, ki so pomembni za realne požarne scenarije, in kateri so primerni za uporabo pri ocenjevanju nevarnosti požara in načrtovanju požarne varnosti. Ta osnovna varnostna objava je namenjena temu, da jo uporabljajo tehnični odbori pri pripravi standardov v skladu z načeli, opredeljenimi v Vodilu 104 IEC in Vodilu 51 ISO/IEC. Ena od odgovornosti tehničnega odbora je, če je to primerno, uporabiti temeljne varnostne objave pri pripravi svojih objav. Zahteve, preskusne metode ali preskusni pogoji te temeljne varnostne objave se ne uporabljajo, razen če se ustrezne publikacije nanje izrecno sklicujejo ali jih vključujejo.
