Nozle: Zone 1 - a sphere of radius R 1 = 1.5 m from the outlet of the pressure relief valve and Respiratory Division 2 for a distance of 2m from the end of Zone 1. Reservoir: Zone 2 - R 2 = 2 m from the tank shell. Hazardous areas: Nozzle: Zone 1 - a sphere of radius R 1 = 1.5 m from the outlet of the pressure relief valve and Zone 2 for a distance
Inside valve, zone 20; Outside valve, zone 21,22, no zone 250. Explosion Class ATEX. St1. Kst (bar m/s). 200. Min vessel size (m3). 0,9. Minimum vessel size
Zone 0 >1000 hours, Zone 2 < 10 hours and Zone 1 in between. These were used in the old BS standard but then dropped and not referenced in the Atex standards as the absolute figures do not sit well with statistical risk analysis techniques but are still commonly erroneously quoted. Hybrid Zones Ex-Machinery explains “which ATEX equipment may be used in which ATEX zone?” put this practical overview on your bulletin board . Within Europe, when electronic or electrical equipment of any kind is intended for use in a potentially hazardous area, the equipment must be ATEX-certified – per the EU directive 2014/34, which is more commonly known as the ATEX 114 directive (derived from Se hela listan på assured-systems.com The process is strongly influencing the ATEX zoning.
More information >> ATEX Fans – Making The Right Choice >> If an explosive atmosphere of flammable substances is specified, the following zones may exist: ATEX zones for gases/vapour: Zone 0 (gases/vapours): an area in which an explosive mixture is continuously present or present for long periods. Nous vous présentons ci-dessous les différentes classes de températures ATEX selon NEC 500, NEC 505, CENELEC et IEC, applicables aux ATEX et avec règles de limitation différentes selon les températures. Ces gammes de températures (T1 à T6) permettent alors de classer les appareils destinés à être installés ou utilisés en zone ATEX. la zone ATEX 2: dans ces zones, le risque ne survient que dans des circonstances de fonctionnement particulières, ou en fonctionnement normal, mais dans ce cas, il est de courte durée.

Minimum vessel size Inside valve, zone 20. • Outside *B-FLAP I, sizes 100-400, St1 marked, may be used on light metal dust Position sensor ATEX version (zone 21, 22, no zone).
De werkgever is verplicht de explosiegevaarlijke zones te markeren. Bij het in kaart brengen van de zones biedt ATEX 153 niet veel soelaas. In Nederland werden de NPR 7910-1 en 2 gebruikt en tegenwoordig is er een IEC norm, de IEC 60079-10-1:2015. Brandbare gassen, dampen en nevels in combinatie met lucht (GAS) Zone 0

Armoured flexible cable suitable for fixed electrical installations in premises with which the equipment is selected within these zones. The ATEX Directive 94/9/EC was implemented in Italy with Legislative Decree 126/98 and applies to products placed on the market and/or in service after 1 July 2003. The ATEX Directive 99/92/EC was implemented in Italy with Legislative Zones System (IECEx/ATEX/Canada & US) ZONE: Hazardous areas are classified into Zones based upon the frequency of the occurrence and duration of an explosive : Gas: Dust gas/dust atmosphere, as follows: O: 20: A potentially flammable atmosphere is present continuously or : Hazardous area classifications and zones › Guidance on creating a compliant working environment › A guide to choosing safe, ATEX approved weighing equipment for your business.
