3 What is Explosion Proof (EX)? Electric Powered Industrial Equipment, used in areas containing explosive or flammable materials, must be designed to prevent any operation of the equipment from igniting the atmosphere. The design and construction of EX Equipment permit their classification as Explosion Proof (EX) and enable their use in explosive and hazardous atmospheres.

4 EXPLOSION PROOF ENCLOSERES An EX Enclosure is a case or housing that has been tested and approved to contain electrical components. The strength of the enclosures must contain any internal explosion. The enclosures have been hydrostatically tested for internal explosive resistance to pressures in excess of UL requirements without failure. Explosion Proof Enclosures protect all cabling, wiring, and electrical components.

5 What is ATEX Explosion Proof (ATEX EX)? ATEX EX (also referred to as Flameproof) is European Explosion Proof equipment certified to ATEX standards. Equipment and protective systems intended for use in potentially explosive atmospheres must enclose all ignition sources. ATEX EX is equipment that complies with ATEX (94/9/EC Directive) (Definition in the following slide). Approved by Internationally Recognized Testing Laboratories, ATEX EX Equipment can be used in designated explosive and hazardous atmospheres.

6 What is the actual differences in Stainless Steel between the 316L or 304 housing? What are advantages of each housing type? The main difference is on the percentage of nickel (Ni), the Ni in 316L is much more than in the 304, so the 316L is much better suitable for corrosion proof capability. All products are for Class 1, Division 1. Class 1 : means the explosive gas area Division 1 : means the explosive gas always exist. 316L Stainless Steel is with Mo (molybdenum) inside and can withstand the corrosion better than 304ss. Example: For marine use, the 316L is recommended. 316L delivery time is rather longer than 304ss.

7 Abbreviation Example: The ATEX certificate for SVEX-Q18 is II 2G EExd tD II B +H2 T6 II 2G: Equipment group II (Equipment intended for use in areas other than mines (above ground). In Places which explosive atmospheres caused by gas, vapors and liquid) zone 1 (gas), equal US standard Class 1, Division 1. EEx: EX mark d: Flame proof structure tD:Dust Explosion Proof II: Equipment group II (Equipment intended for use in other areas than mines (above ground) in areas which have explosive atmospheres, which is caused by gases, vapors and liquids) B+H2: gas group B plus hydrogen. T6: Max surface temperature 85 degree.

8 Group I – Electrical apparatus for mines susceptible to firedamp (for use underground) Group II – Electrical apparatus for places with a potentially explosive atmosphere, other than mines susceptible to firedamp

9 General information According to 94/9/EC, a device that is to be used in an environment at risk of explosion may only be brought into the market if it satisfies the standards specified in the norm. Compared with the previous directives, it must be noted that the specification refers not only to electrical but also to mechanical equipment Ex: PTZs. Devices are divided into categories and groups to accurately define the conditions of use. This definition is marked on the device and may appear as follows: II 2G EEx IIC T6 Device group Category Example: Identifier Explosion group Temperature class

10 Device group II, There are 2 groups of devices. Devices of Group I, Category M are for use in underground mines and their above ground equipment, which are at risk from firedamp and/or inflammable dusts. (This is not given further coverage in this document). All other areas at risk of explosion are combined in Device Group II. Identifier EEx defines that this is an electrical device. d: Flame proof structure tD: Dust Explosion Proof

11 Category The categories define which zones the devices may be used in. The classification states how frequently and in what concentration the ignitable mixture occurs. Furthermore, differentiation is made as to whether the hazard is due to gases, vapors and mists or due to dust.

12 Category 1 For devices, which guarantee a very high level of safety. Intended for the case where an atmosphere at risk of explosion is to be expected frequently or continuously. Devices in this category can also be used in Category 2 and 3. Inflammable gases, vapors or mists Zone 0 equivalent to Category 1G Area in which an atmosphere at risk of explosion as a mixture of air and inflammable gases, vapors or mists is continuously or frequently present or present for long periods. Inflammable dusts Zone 20 equivalent to Category 1D Area in which an atmosphere at risk of explosion in the form of a cloud of inflammable dust contained in the air is continuously or frequently present or present for long periods.

13 Category 2 For devices, which guarantee a high level of safety. Intended for the case where an atmosphere at risk of explosion is to be expected. Devices in this category can also be used in Category 3. Inflammable gases, vapors or mists Zone 1 equivalent to Category 2G Area in which an atmosphere at risk of explosion as a mixture of air and inflammable gases, vapors or mists can form occasionally during normal operation. Inflammable dusts Zone 21 equivalent to Category 2D Area in which an atmosphere at risk of explosion in the form of a cloud of inflammable dust contained in the air can form occasionally during normal operation.

14 Category 3 For devices, which guarantee a normal level of safety. Intended for the case where an atmosphere at risk of explosion is to be expected rather infrequently and, if so, for only short periods. Inflammable gases, vapors or mists Zone 2 equivalent to Category 3G Area in which an atmosphere at risk of explosion as a mixture of air and inflammable gases, vapors or mists does not normally occur at all or only for short periods during normal operation. Inflammable dusts Zone 22 equivalent to Category 3D Area in which an atmosphere at risk of explosion in the form of a cloud of inflammable dust contained in the air does not normally occur at all or only for short periods during normal operation.

15 Explosion group Device group II is sub-divided into Explosion Groups A, B or C. This classification is dependent on the typical material properties of the gases and vapors that occur. The hazard level of materials increases from Explosion Group IIA to IIC. The requirements for the devices increase accordingly. If a device is approved for IIC, it can be used for all other explosion groups. Alternatively, the chemical formula or the name of the material can be stated here.

16 Temperature class It must be ensured that the ignition temperature of an inflammable material is not reached during operation. Forthis purpose, the maximum surface temperature of a device must be less than the minimum ignition temperature. For this reason, the maximum surface temperature of equipment for use with inflammable gases, vapors or mists is specified in temperature classes. For dusty environments, the maximum surface temperature is specified in °C. Temperature classMaximum permissible surface temperature of the equipment (°C) T1450 T2300 T3200 T4135 T5100 T685
