3 E Switches in conformity with ATEX directive / Technical concepts ATEX Directive The ATEX mark (Atmospheres Explosives) refers to two European directives concerning the risk of deflagration in potentially explosive atmospheres: - ATEX 9/9/CE: concerns the requirements for electrical and non-electrical equipment used in potentially explosive environments. According to this directive the manufacturer has to comply with the provided requirements and mark the articles in conformity with particular categories. - ATEX 99/9/CE: regards the minimum safety and sanitary requirements that the user has to satisfy during the activity in potentially explosive environments. These directives determine the requirements for the safety and health protection of people, animals and property and carry several procedures for the conformity demonstration of equipment to the directive requirements. Classification of the potentially explosive atmospheres A potentially explosive atmosphere is an atmosphere that could become explosive according to the local conditions of work. Usually it consists in environments where it is present a mixture of air and flammable substances in the form of gas, smog, steams and dusts. The ATEX 99/9/CE directive defines for two types of explosive atmosphere, depending on the presence in the zone of gases or combustible dusts. Each area exposed to these types of explosive atmospheres is classified in three zones, according to the frequency and duration of the explosive atmosphere. For atmospheres with explosive gas, areas are classified in zones 0, and ; for atmosphere with explosive dusts in zones, and : - Zone 0/: a place where gas or combustible dust is present permanently. Constant danger. Equipment of minimum category is required. - Zone /: a place where gas or combustible dust is likely to occur during normal operation. Potential danger. Equipment of minimum category is required. - Zone /: a place where gas or combustible dust is unlikely to occur or only for a short period. Lower danger. Equipment of minimum category is required. It s under the responsibility of the final user to choose and classify the different zones and to use suitable equipments. Equipment categories ATEX 9/9/CE directive distinguishes equipment between two main groups: - Group I: equipment and systems for mining - Group II: equipment and systems for all other applications Equipment of the group I is divided in two further categories according to the required protection degree: - Category M: equipment designed to assure a very high protection degree - Category M: equipment designed to assure a high protection degree Equipment of the group II is divided in three further categories according to the required protection degree: - Category : equipment designed to assure a very high protection degree (use in zones 0 and ) - Category : equipment designed to assure a high protection degree (use in zones and ) - Category : equipment designed to assure a normal protection degree (use in zones and ) Environment characteristics Equipment characteristics Environment of application Flammable material Potentially explosive atmosphere Classifications of the potentially explosive atmospheres: ZONE Required marking of the applied device: CATEGORY Required marking of the applied device: GROUP Required degree protection Mining M M I very high high It is present continuously, for long periods or frequently 0 G very high Gases It is likely to occur G or G high Surface It is unlikely to occur or, if it does, is likely to do infrequently and for a short period only G, G or G normal II It is present continuously, for long periods or frequently D very high Dusts It is likely to occur D or D high It is unlikely to occur or, if it does, is likely to do infrequently and for a short period only D, D or D normal page /9 General Catalog 09-0

4 Methods of protection In order to avoid an explosion caused by the electrical ignition of an explosive atmosphere, it is possible to take different type of precautions: - Isolate the dangerous parts into housing in order to limit the explosion inside itself. - Avoid contact between ignition sources and the potentially explosive atmosphere interposing solid, liquid or gaseous materials. - Take measures in order to limit the generation of dangerous ignition sources, eliminating the possibility of faults or limiting the energy so it s not sufficient to cause the ignition. For each modality several methods of protection have been developed and standardized, as listed in the following table. Table - Protection methods and reference standards Protection method Symbol Marking Zone of utilization CENELEC standard General requirements Example of marking Devices for places with gases presence II G EEx ia IIC T6 Community marking Equipment group (see table ) Protection category (see table ) Prefix for safety devices according to the CENELEC standard Method of protection (see table ) Classification of gases (see table ) Temperature class (see table ) Devices for places with dusts presence II D IP6 T80 C Community marking Equipment group (see table ) Protection category (see table ) Protection degree (see table ) Maximum surface temperature of the equipment / / / EN 00 Oil immersion EEX o or EN 00 Pressurized EEX p or EN 00 Sand encapsulation EEX q or EN 00 Explosion-proof enclosure EEX d or EN 008 Increased safety EEX e or EN 009 Intrinsic safety EEX ia EEX ib 0, or EN 00 Encapsulation EEX m or EN 00 Type of protection / EEX n EN 00 Protection by housing IP // EN 0-- Temperature classes Table Classes T T T T T T6 Maximum surface temperature of the equipment 0 C 0 C 0 C C 00 C 8 C Classification of gases Table (excerpt standard IEC 0) T T T I IIA IIB IIC methane propane, methane, ethane, benzene, ammoniac, acetic acid, carbon monoxide, methanol, toluene ethanol, amyl acetate, butane fuel oil, hexane acrylonitrile ethylene hydrogen sulphide T acetaldehyde ethyl ether T T6 hydrogen acetylene carbon bisulphide A B A B C D E A B C A B C D E F G H 6 General Catalog 09-0 page /
