L'IEC 63154:2021 spécifie les exigences, les méthodes d’essai et les résultats d’essai exigés lorsque des normes sont nécessaires pour fournir un niveau de protection de base contre les incidents de sécurité informatique (c’est-à-dire les tentatives malveillantes, qui ont un effet réellement ou potentiellement néfaste sur les matériels, sur leurs réseaux ou sur les informations qu’ils…
FTIR analysis of fire effluents in cone calorimeter tests
This document specifies a method for determining the kinetics and yields of gaseous emissions from a specimen exposed to radiant heat in a cone calorimeter. Gas yields are determined by exposing small representative specimens to an external heat flux with or without spark ignition. The concentrations of specific gases in the effluent (smoke) are measured. In combination with calculated masses of…
