Annotation of standard text ISO/IEC 80079-20-2-ed.1.0 :
ISO/IEC 80079-20-2:2016 is published as a dual logo standard and describes the test methods for the identification of combustible dust and combustible dust layers in order to permit classification of areas where such materials exist for the purpose of the proper selection and installation of electrical and mechanical equipment for use in the presence of combustible dust. The standard atmospheric conditions for determination of characteristics of combustible dusts are: - temperature -20 °C to 60 °C, - pressure 80 kPa (0,8 bar) to 110 kPa (1,1 bar) and - air with normal oxygen content, typically 21 % v/v. The test methods defined do not apply to: - recognized explosives, propellants (e.g. gunpowder, dynamite), or substances or mixtures of substances which may, under some circumstances, behave in a similar manner or - dusts of explosives and propellants that do not require atmospheric oxygen for combustion, or to pyrophoric substances. This first edition cancels and replaces the first edition of IEC 61241-2-1 published in 1994, the first edition of IEC 61241-2-2 published in 1993 and the first edition of IEC 61241-2-3 published in 1994, combining the requirements into a single document, and is considered to constitute a technical revision. Significant changes with respect to IEC 61241-2-1:1994, IEC 61241-2-2:1993 and IEC 61241-2-3:1994 can be found in the foreword of the document. The contents of the corrigendum of March 2017 have been included in this copy. Keywords: combustible dust ISO/IEC 80079-20-2:2016 est publiee en tant que norme sous double logo et decrit les methodes dessai pour lidentification des poussieres combustibles et des couches de poussieres combustibles afin de permettre le classement des emplacements ou de tels produits existent, et ce, pour un choix et une installation corrects des equipements electriques et mecaniques a utiliser en presence de poussieres combustibles. Les conditions atmospheriques normales pour la determination des caracteristiques des poussieres combustibles sont les suivantes: - temperature de -20 °C a 60 °C, - pression de 80 kPa (0,8 bar) a 110 kPa (1,1 bar) et - air avec teneur normale en oxygene, generalement egale a 21 % v/v. Les methodes dessai definies ne sappliquent pas aux: - explosifs proprement dits, agents propulseurs (par exemple, poudre a canon, dynamite) ou substances ou melanges de substances qui, dans certaines conditions, peuvent se comporter de maniere semblable ou - aux poussieres dexplosifs et agents propulseurs qui nexigent pas doxygene atmospherique pour leur combustion, ou aux substances pyrophoriques. Cette premiere edition annule et remplace les premieres editions de lIEC 61241-2-1, de lIEC 61241-2-2 et de lIEC 61241-2-3 parues respectivement en 1994, 1993 et 1994, en regroupant les exigences dans un seul document. Cette edition constitue une revision technique. Modifications majeures par rapport a lIEC 61241-2-1:1994, lIEC 61241-2-2:1993 et lIEC 61241-2-3:1994 et sont identifies dans lavant-propos du document. Le contenu du corrigendum de mars 2017 a ete pris en consideration dans cet exemplaire. Mots cles: poussieres combustibles
