Plastics - Smoke generation - Determination of optical density by a single-chamber test (ISO/DIS 5659:2024)

ISO 5659-2:2017 specifies a method of measuring smoke production from the exposed surface of specimens of materials or composites. It is applicable to specimens that have an essentially flat surface and do not exceed 25 mm in thickness when placed in a horizontal orientation and subjected to specified levels of thermal irradiance in a closed cabinet with or without the application of a pilot flame. This method of test is applicable to all plastics.
It is intended that the values of optical density determined by this test be taken as specific to the specimen or assembly material in the form and thickness tested and are not to be considered inherent, fundamental properties.
The test is intended primarily for use in research and development and fire safety engineering in buildings, trains, ships, etc. and not as a basis for ratings for building codes or other purposes. No basis is provided for predicting the density of smoke that can be generated by the materials upon exposure to heat and flame under other (actual) exposure conditions. This test procedure excludes the effect of irritants on the eye.

Plastiques - Production de fumée - Détermination de la densité optique par un essai en enceinte unique (ISO/DIS 5659:2024)

ISO 5659-2:2017 spécifie une méthode pour le mesurage de la production de fumée provenant de la surface exposée d'éprouvettes constituées par des matériaux ou des composites. Elle est applicable à des éprouvettes qui ont une surface essentiellement plane et dont l'épaisseur est inférieure à 25 mm, lorsqu'elles sont orientées horizontalement et soumises à des niveaux spécifiés d'éclairement énergétique thermique dans une enceinte fermée, avec ou sans utilisation de flamme pilote. La présente méthode d'essai est applicable à tous les plastiques.
Les valeurs de densité optique déterminées par le présent essai sont propres au matériau de l'éprouvette ou de l'assemblage soumis à essai, sous la forme et avec l'épaisseur sélectionnées pour l'essai. Ces valeurs ne doivent pas être considérées comme révélatrices de propriétés de base, inhérentes au produit.
L'essai est principalement destiné à être utilisé en recherche et développement et en ingénierie de sécurité incendie dans les bâtiments, les trains, les navires, etc., et non en tant que base d'appréciation pour des codes de construction ou pour d'autres fins. Aucun élément fondamental n'est fourni pour prévoir la densité de la fumée susceptible d'être produite par les matériaux exposés à la chaleur et à une flamme dans d'autres conditions (réelles) d'exposition. Le présent mode opératoire d'essai ne traite pas de l'effet des irritants sur les yeux.
