Atex Zone 1 Classification

Classification of ATEX zones ATEX zones are classified according to two parameters the types of combustibles that may be encountered (dust or gas) the frequency or duration during which an explosive atmosphere is likely to occur Warnings Carefully read the Instructions for Use used in this technical advice before consulting the advice.

Atex zone 1 classification. 2 – Can be used in zones 1 or 21;. The directive does not use Zone numbers in the classification of hazardous areas, preferring to refer to their definitions (eg ‘An area where an explosive atmosphere occurs frequently or continuously’ for Zone 0) but it is useful to understand the classification system commonly used to describe areas where explosive atmospheres may occur. First of all, Zone 2 certified equipment is not allowed to be carried through a Zone 1 environment, not even when the Zone 2 equipment is powered off Secondly, if there is an emergency, all zones are automatically upgraded to a Zone 1, immediately making all Zone 2 equipment in violation with the guidelines.

The ATEX standard also has a classification for explosive gases and dusts, with Group I referring to methane gases and coal dust (mining), while Group IIA to IIC gases and Group IIIA and IIIC dusts (above ground industries) have been categorised according to their different igniting power, with IIA/IIIA being the least dangerous and having the highest ignition temperature and IIC/IIIC the most dangerous with the lowest ignition temperature. ATEX Classification Category 2 and 3 (gas);. Start date Oct 24, 17;.

ATEX 137 Classification of Hazardous Areas In accordance with the 1999/92/EC Directive, hazardous areas are classified as A place in which an explosive atmosphere consisting of a mixture with air or flammable substances in the form of gas, vapour or mist is • Zone 0 (Category 1 equipment) present continuously or for long periods or.

ATEX The ATEX directive uses zones to classify potentially explosive gas and dust. T3 IEC Classification Zone 2 and 22;. In part 1 of our ATEX blog series, we set about demystifying the often confusing world of ATEX markings In this second blog, we will delve into ATEX equipment classification to add more clarity to the subject, while using Eyecon 2 as an example Equipment is classified as either suitable for underground mining ‘I’ operations or classified as ‘II’ for nonmining environments.

Zone 1 (21) and Zone 2 (22) hazardous area enclosures for instrumentation, small power or lighting applications – stainless steel, mild steel, glass reinforced polyester, aluminium and polycarbonate certified according to ATEX and IECEx Also high voltage junction boxes for jointing, terminating and connecting 33kV, 66kV, 11kV and 33kV power cables in Zone 2 hazardous area. A Zone 1 area is classified as a place in which an explosive atmosphere consisting of a mixture with air or flammable substances in the form of gas, vapour or mist is likely to occur in normal operation occasionally These are typically process areas where gases are more likely to be present. Classification of ATEX zones Explosive atmosphere Gas type combustible substance Dust type combustible Present permanently or for long periods (more than 1000 h per year) ZONE 0 ZONE Present occasionally.

You probably don’t think so, but we promise you that there is an obvious explanation. For use in ATEX zone 1, category 2 explosionproof equipment is required Does this make sense?.

Groups IIA, IIB and IIC;. 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. Understanding ATEX Zones for Gas & Dust This week we look at ATEX zones for gases and dust to dig a little deeper into ATEX understanding If you are not sure whether you need an explosion proof ATEX fan or need to know the ATEX zone in which your application is classified, please consult an official authority in your country ATEX is an acronym derived from the words “Atmospheres.

Class 1 / Division 2 ATEX Zone 2 Yellow Zone Industrial Computing for Class 1 / Division 2 and ATEX Zone 2 Where embedded electrical products are concerned, the requirement for harsh environment industries such as oil and gas will usually be certification to Class 1 / Division 2 and/or ATEX Zone 2. Classification of equipment The ATEX directive classifies equipment into groups and categories which are defined by the marking on the equipment – see “Product marking” below Class I Division 1 (gases) Zone (dusts) Class II Division 1 (dusts) Zone 1 (gases) An area in which an explosive mixture is likely to occur in normal operation. Zone Zone defines the general nature if it is a gas or dust and the probability of hazardous material being present in an ignitable concentration in the surrounding atmosphere The Zone system has three levels of hazard for gas or dust where the Division system has two Gases, Vapors and Mists Article 505 National Electrical Code (NEC).

It is worth noting that ATEX maintenance and repair obligations depend on the category of the equipment rather than the zone in which it is installed Therefore, putting Category 1 equipment, which has a very high level of safety and is designed for use in Zone 0 or Zone areas, into a Zone 2 area could have longterm financial implications.

ATEX zones for gases/vapour Zone 0 (gases/vapours) an area in which an explosive mixture is continuously present or present for long periods Zone 1 (gases/vapours) an area in which an explosive mixture is likely to occur in normal operation Zone 2 (gases/vapours) an area in which an explosive mixture is not likely to occur in normal operation and if it occurs it will exist only for a short time. Areas within these two kinds of explosive atmospheres are each divided into three subzones Although the zones characteristics are identical for both gas and dust, their numbering is different Zone 0, 1 and 2 refer to gas and Zone , 21 and 22 refer to dust Permanent presence of explosive gasses or combustive dust. ATEX zone 1 classification Thread starter ksa74f;.

ZONE 0 Area in which an explosive gas atmosphere is present continuously or for long periods or frequently ZONE 1 Area in which an explosive gas atmosphere is likely to occur in normal operation occasionally. 1 G 0, 1, 2 Explosive Atmosphere 2 G 1, 2 3 G 2 D is added after G in the certification class number D = Dust (ie GD) if device is dust category approved also 1 D , 21, 22 2 D 21, 22 3 D 22 Explanation of the categories 1 Very high safety = device safety must be guaranteed even in case of rare device failures, eg. Atex zone 1 A atex zone 1 is similar to a zone 0 However, a zone 1 is a place in which an explosive atmosphere is likely to occur in normal operation occasionally, instead of a continuously presence of a hazardous atmosphere Atex zone 2 In a atex zone 2, a explosive atmosphere is not likely to occur in normal operation.

Regarding ATEX 99/92/EC Directive, the requirement is that Employers must classify areas where potentially explosive atmospheres may occur, into zones The classification given to a particular zone, and its size and location, depends on the likelihood of an explosive atmosphere occurring and its persistence if it does. Example of Zone Classification (Filling Station) Remark In Zone 0 – Exequipment must be designed for Category 1 use In Zone 1 – Ex equipment must be designed for Category 2 use In Zone 2 – Ex equipment must be designed for Category 3 use IP Classification’s – Ingress Protection to EN Definition 1st code index Code IP Class Code Definition 2nd code index. Every hazardous environment with a risk of combustion is given a zone rating dependant on the type of hazard You should only use equipment specified for the zone you’re working in The following combinations are possible 1 – Can be used in zones 0 or ;.

ATEX directive Classification of operating resources Components and solutions with ATEX certification for all steps in the automation process Legal directives such as NEC/CEC in the USA and Canada, and Europe’s 14/34/EU (ATEX) are in place alongside other regulations to reduce the risk of explosions in high risk operating areas and. ATEX Zone 1 Definition – What is Zone 1?. Groups IIA, IIB and IIC;.

3 – can be used in zones 2 or 22. Area Classification Increase safety and lower costs with accurate Area Classification Of all the fields covered by ATEX and DSEAR, hazardous area classification is perhaps the most misunderstood Inexperienced practitioners in area classification simply review areas and allocate a classification in accordance with codes of practice (for example, Zone 1 for 1 meter then Zone. T3 IEC Classification Zone 1 and 2;.

For hazardous areas involving dusts then the above classifications are prefixed with a "2", so zone 1 for dusts becomes zone 21, as below Zone A place in which an explosive atmosphere in the form of a cloud of combustible dust in air is present continuously, or for long periods or frequently. Area classification for gases and vapours, and its equivalent for dusts was published in 02as BS EN /3 These standards form a suitable basis for assessing the extent and type of zone, and can be used as a guide to complying with the requirements in DSEAR However, they cannot give the. Zonex Enclosures are designed and certified to meet ATEX Directive 94/9/EC as well as IECEx and AEx standards for increased safety in housing electrical components in Zone 1 and Zone 2 applications nVent HOFFMAN'S ATEX Ex e enclosures are not intended for use in explosionproof or flameproof applications.

With the old CENELEC (previous Directive), different areas were divided into three classifications Zone 2, Zone 1, and Zone 0 depending on the level of risk With the ATEX Directive, every Zone is associated to a Category, and every electrical equipment is classified according to these categories, certifying in which areas it can be safely used. Zone 0 An area where an explosive atmosphere is present continuously or for long periods;. Zone 2 An area where an explosive atmosphere is not likely to occur in normal operation.

You probably don’t think so, but we promise you that there is an obvious explanation. ATEX Directive 14/34/EU is a «new approach» directive that applies to protective systems against explosions as well as all equipment used in or related to explosive atmospheres, such as electrical and nonelectrical equipment, components and safety devices, control and adjustments necessary for the safe operation of this equipment and protective systems.

A atex zone 1 is similar to a zone 0 However, a zone 1 is a place in which an explosive atmosphere is likely to occur in normal operation occasionally, instead of a continuously presence of a hazardous atmosphere Atex zone 2 In a atex zone 2, a explosive atmosphere is not likely to occur in normal operation. Zone 1 An area where an explosive atmosphere is likely to to occur in normal operation;. ATEX The ATEX directive uses zones to classify potentially explosive gas and dust atmospheres Classifications range from an ignitable condition being an unlikely occurrence (Zones 2 and 22) to continuously present (Zones 0 and ) > Gas / Vapour / Mist Zone 0, Zone 1, Zone 2 > Powder / Dust Zone , Zone 21, Zone 22 ExProof.
