EN 15188:2007

Determination of the spontaneous ignition behaviour of dust accumulations

This European Standard specifies analysis and evaluation procedures for determining self-ignition temperatures (TSI) of combustible dusts or granular materials as a function of volume by hot storage experiments in ovens of constant temperature. The specified test method is applicable to any solid material for which the linear correlation of lg (V/A) versus the reciprocal self-ignition temperature 1/TSI (with TSI in K) holds (i.e. not limited to only oxidatively unstable materials).
This European Standard is not applicable to the ignition of dust layers or bulk solids under aerated conditions (e.g. as in fluid bed dryer).
This European Standard shall not be applied to dusts like recognised explosives that do not require atmospheric oxygen for combustion, nor to pyrophoric materials.
NOTE   Because of regulatory and safety reasons "recognised explosives" are not in the scope of this European Standard. In spite of that, substances which undergo thermal decomposition reactions and which are not "recognised explosives" but behave very similarly to self-ignition processes when they decompose are in the scope. If there are any doubts as to whether the dust is an explosive or not, experts should be consulted.

Bestimmung des Selbstentzündungsverhaltens von Staubschüttungen

Détermination de l'aptitude à l'auto-inflammation des accumulations de poussières

La présente Norme européenne prescrit des modes opératoires d’analyse et d’évaluation permettant de déterminer les températures d’auto-inflammation (TAI) de poussières combustibles ou de matériaux granulaires en fonction de leur volume par des essais d’étuvage dans des étuves de séchage à température constante. La méthode spécifiée est applicable à toute matière solide (c’est à dire que son applicabilité ne se limite pas aux seules matières instables par oxydation) pour laquelle se vérifie une corrélation linéaire entre le logarithme log (V/A) et l’inverse de la température d’auto-inflammation 1/TAI ( avec TAI en Kelvins).
La présente Norme européenne n’est pas applicable à l’inflammation des couches de poussière ou des masses solides dans des conditions aérées (comme par exemple dans un sécheur en lit fluidisé).
Cette méthode ne s’applique pas aux poussières, comme les explosifs reconnus comme tels, dont la combustion ne nécessite pas d’oxygène, ou aux substances pyrophoriques.
NOTE   Pour des raisons réglementaires et de sécurité, les « substances reconnues comme explosives » sont exclues du domaine d’application de la présente norme. Malgré cela, les substances qui subissent des réactions de décomposition thermique et qui ne sont pas des « substances reconnues comme explosives » mais dont le comportement est très similaire à celui de processus d’auto-inflammation lorsqu’elles se décomposent font partie du domaine d’application. En cas de doute sur la caractérisation des poussières comme explosifs ou non, il convient de consulter des experts.
