Explosive atmospheres - Part 20-2: Material characteristics - Combustible dusts test methods (ISO/IEC 80079-20-2:2016)
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.

Explosionsfähige Atmosphären - Teil 20-2: Werkstoffeigenschaften - Prüfverfahren für brennbare Stäube (ISO/IEC 80079-20-2:2016)
Dieser Teil von ISO/IEC 80079 beschreibt die Prüfverfahren für die Identifizierung von brennbarem Staub und Ablagerungen brennbarer Stäube, um die Klassifizierung von Bereichen, in denen solche Stoffe vorkommen, zum Zweck der Auswahl und Montage von elektrischen und mechanischen Ausrüstungen, die für die Verwendung in Gegenwart von brennbarem Staub geeignet sind, zu ermöglichen.
Die atmosphärischen Normzustände zur Bestimmung der Eigenschaften von brennbaren Stäuben sind
— Temperatur −20 °C bis +60 °C,
— Druck 80 kPa (0,8 bar) bis 110 kPa (1,1 bar) und
— Luft mit normalem Sauerstoffgehalt, typischerweise 21 % v/v.
Die definierten Prüfverfahren sind nicht anwendbar auf
— anerkannte Sprengstoffe, Treibstoffe (z. B. Schießpulver, Dynamit) oder auf Stoffe und Stoffgemische, die sich unter Umständen ähnlich verhalten können oder
— Stäube von Sprengstoffen und Treibstoffen, die keinen atmosphärischen Sauerstoff zur Verbrennung benötigen oder auf pyrophore Stoffe.

Eksplozivne atmosfere - 20-2. del: Lastnosti materiala - Metode preskušanja gorljivega prahu (ISO/IEC 80079-20-2:2016)
Ta standard opisuje preskusne metode za ugotavljanje, ali so za material značilne lastnosti, ki se upoštevajo kot gorljiv prah, in za ugotavljanje lastnosti gorljivih prahov. Ta preskusna metoda se uporablja za določanje in razvrščanje območij, v katerih so prisotne eksplozivne prašne atmosfere in gorljive plasti prahu, da se omogoči ustrezna ocena potencialnih virov vžiga opreme, ki jih je treba uporabljati pri konstrukciji in uporabi opreme, ki se uporablja v prisotnosti gorljivega prahu. Opredeljene preskusne metode se ne uporabljajo za: – znane eksplozive, smodnik, dinamit ali snovi ali mešanice snovi, ki lahko v nekaterih okoliščinah delujejo podobno; ali – prah eksplozivov, ki za gorenje ne potrebuje atmosferskega kisika, ali piroforne snovi.
