T0700. Explosive atmosphere Conditions n explosion can occur if the following factors are combined: Presence of inflammable substances Presence of an ignition source or inflammation source: fire, flame, electrical or mechanical sparks, overheated surfaces, electrostatic discharges Oxygen Inflammable substances can be listed as follow: Inflammable gas Inflammable liquid Inflammable dust Liquid gas: butane, butene, propane, propylene Smoke: carbon monoxide, methane Chemical gas substances : acetylene, acetylene oxide, vinyl chloride Solvents Fuel Oil Heating oil Painting Chemical substances Coal Wood dust Human and animal food : sugar, flour, cereal... Plastic material Metal Ignition source: Electrical energy may be dangerous if used close to an inflammable substance as it is considered as a potential source of ignition. Indeed, sparks, arcs or dangerous temperature levels are generated by the electrical energy. Protection: Particular methods of protection have thus been investigated in order to allow the use of electrical equipment in hazardous areas. Concerned industries The risk of explosion is particularly high in certain types of industries, which generate inflammable gas, inflammable liquid or inflammable dust. Indeed, the new TEX directive now considers the explosion risk caused by dust. We can list: Refineries, Petrochemical and chemical industries, Off shore installations, Mining industries, Human and food industries
T0700. Explosive atmosphere (cont.) The risk can be expressed as follow: Industries Refineries Petrochemical and chemical industries Pharmaceutical and cosmetic industries Waste and water recycling industries Painting facilities Gas distribution Human and animal food industries Wood saw mills, metal machining Risks Treatment of hydrocarbon highly inflammable Transformation and treatment processes which can generate explosive mixing Use of alcohol highly inflammable like solvents Use of active material or adjuvant which can create explosive dust Paper or plastic dust Storage of barrels or containers partially or not emptied Gas fermentation emission during water treatment Over spray formation during the lacquering of surfaces with spray gun Transport and stocking of cereal, powder which can create potentially dust explosive atmospheres in filters and aerators Metal dust generation during metal polishing which can create dust explosive atmospheres in collectors Génération de poussières métalliques lors du polissage des métaux qui peuvent créer une atmosphère explosible dans les collecteurs 3
T0700 B. European explosion directives TEX European directive consists in two parts : TEX 94/9/EC (generally called TEX 95), which concentrates on the duties of the manufacturers. TEX 999/92/EC (generally called TEX 37), which focuses on the end users obligations. * Directive applicable to entrelec terminal blocks The objectives of the directives "Minimum requirements" is a key phrase of the directives - member states are free to introduce more stringent measures if they wish. TEX belongs to the group of the so-called "new approach" directives. Under a new approach directive, any route towards achieving the objective is permitted. The European commission will not interfere with how a technical solution is reached, but gives all parties involved the freedom to define the best means, methods and procedures to meet the guidelines. This gives rise to a division of responsibilities between the equipment manufacturer and the end user. The less responsibility the equipment manufacturer assumes for achieving the solution, the more the end user will have to take on, and vice versa. 4
T0700 B. European explosion directives (cont.) TEX 95: Equipments and components The objective of the TEX 95 directive is to reinforce safety aspects. It is more restricting than the former directive 76/7 EEC, as it does not only concentrate on the product but on the whole process. The manufacturer s quality assurance is now audited through the relevant standard NF EN 3980 Potentially explosive atmospheres - pplication of quality systems. Extract of the EN 3980 7.5.3: The manufacturer shall establish and maintain procedures for product identification during all the stages of production, testing, final inspection and placing on the market. Traceability is required with respect to final product and its significant parts. The "production quality assurance notification" is the highest assurance quality certification level achievable. TEX products are considered as safety devices: the entire process from the design to the installation must be strictly controlled. Product and company quality assessment which allow design, manufacturing and sales. Requirements in terms of organization for designing, manufacturing and selling. BB commitments versus TEX 95 Terminal blocks are unitary controlled - unitary dielectric control on finished product Maximized security is guaranteed through dedicated manufacturing processes, dedicated manufacturing sites and dedicated inventory locations. Reinforced traceability for accurate identification of the TEX customers through dedicated part numbers for the TEX range and batch number registration. TEX 37: Installations The addition of the new "workers directive TEX 37" reinforces the safety level even further. Risk analysis: requires that the employers draw up evidence of risk analysis for their site. rea classification: area classification into zones and site inspections must be carried out where potentially explosive atmospheres may develop. Explosion protection document: Information such as written instructions, training programs, and clearance for work must be defined in the "explosion" protection document" and respected in order to guarantee the protection of the staff. TEX certified products must be selected according to zone. Locations where explosive atmospheres may occur and identified through warning signs. BB commitments versus TEX 37 Reliable product information is given to the end user: increased safety and intrinsic safety certified terminal blocks for safe installation. Excellence of DO system in regards to the TEX 37 minimum requirements (training programs, written instructions, clearance for work ): - Simplified "clearance for work": no possibility of unauthorized modifications thanks to the DO system dedicated tool (OUMD, OUPD or OUTD). - Maximized "correct installation and operation, qualification of the personnel": the DO system connection is operator independent. - No retightening maintenance: DO system is a Screwless technology. Dates of enforcement TEX 95: Equipment and components From July st 2003, equipment, protection systems and electrical components used in potentially explosive atmospheres must comply with the European directive TEX 94/9/EC (TEX 95). TEX 95 abrogates the directive 76/7/EC and becomes mandatory for all new equipment installed after 06/30/03. Former Ex products, already in stock, can still be installed if they are to replace used parts in already active installations. Dates of enforcement TEX 37: Installations The TEX 999/92/EC (TEX 37) directive becomes mandatory for all new installations implemented after 06/30/03, in every country member of the EEC. For existing installations, three more years are given to fulfill the minimum requirements. If an old work place is upgraded, modified or extended, it must comply with the "minimum requirements" immediately. 5
T0700 B. European explosion directives (cont.) Definitions and terms Equipment and components used in potentially explosive atmospheres are divided into groups and categories. (tex 94/9/EC, chapter, art, 3c) This classification is meant to define clearly the "intended use" of equipment, protective systems and devices, which is considered of prime importance for safe operation. Groups Two distinct groups according to the industry type in which the equipments or components are to be used: Group I stands for Mine industries: Underground part of mines and surface installations of such mines, liable to be endangered by firedamp and / or combustible dust. Group II stands for Surface industries: ll other places liable to be endangered by explosive atmospheres. Categories TEX defines "categories of equipment", specified by their protection characteristics: For Mine industries: - Category M : very high level of safety - Category M 2: high level of safety For surfaces industries: - Category : very high level of safety - Category 2: high level of safety - Category 3: normal level of safety? Frequently asked question: If equipment is certified in category, is it certified in category 2? Equipment or components certified in category are also certified in category 2 and category 3 since category is the highest level of safety. 6
T0700 B. European explosion directives (cont.) Equipment in category: M (Mine industries) Is required to remain functional, even in the event of rare incidents relating to equipment, with an explosive atmosphere present. M2 (Mine industries) Is intended to be de-energized in the event of an explosive atmosphere. The means of protection relating to equipment in this category assure the requisite level of protection during normal operation and also in the case of more severe operating conditions, in particular those arising from rough handling and changing environmental conditions. (Surface industries) Must ensure the requisite level of protection, even in the event of rare incidents relating to equipment and is characterized by means of protection such that: - Either, in the event of failure of on means of protection, at least an independent second means provides the requisite level of protection. - Or the requisite level of protection is assured in the event of two faults occurring independently of each other. 2 (Surface industries) Must ensure the requisite level of protection, even in the event of frequently occurring disturbances or equipment faults which normally have to be taken into account. 3 (Surface industries) Ensure the requisite level of protection during normal operation. Intended use: In underground parts of mines as well as those parts of surface installations of such mines endangered by firedamp and/or combustible dust. In underground parts of mines as well as those parts of surface installations of such mines endangered by firedamp and/or combustible dust. Zone 0 and Zone 20: reas in which explosive atmospheres caused by mixtures of air and gases, vapors or mists or by air/dust mixtures are present continuously, for long periods or frequently. Zone and Zone 2: reas in which explosive atmospheres caused by mixtures of air and gases, vapors or mists or by air/dust mixtures are likely to occur. Zone 2 and Zone 22: reas in which explosive atmospheres caused by gases, vapors or mists or by air/dust mixtures are unlikely to occur or are likely to do so only infrequently and for a short period only. tex 94/9/EC annex I 0 and 20 zones and 2 zones and 22 zones Explosive atmospheres classification example 7
T0700 C. TEX 94/9/EC conformity assessment procedures The TEX certification process can be identified as two main parts: The EC type examination certificate confirms that the validity of the technical file established by BB is in conformity with the tex directive. Examination and test results of the product are been examined by a notified body. The inspection of quality assurance, conducted by a notified body: refers to the production or product quality assurance examination (depending upon the product level of certification). The notification has three years validity with yearly audit. s said in chapter B, TEX directives objective is to increase the safety. Therefore, a quality assurance audit is now necessary to obtain the TEX certification for any equipment or component. Complete conformity assessment procedure is detailed here below: tex 94/9/EC chapter II, article 8 BB certification conformity "Production Quality Insurance" inspection "EC type examination certificate" Notified bodies "Notified Bodies", are independant bodies which are appointed by the Member States. They have the relevant expertise and facilities to undertake the required procedures such as : " Examination", which involves an assessment made of the product against the Essential Health and Safety Requirements of the Directive. Report of the manufacturer's Quality ssurance procedures to ensure that the "type" will continue to comply with the requirements. These "Notified Bodies" are given a number and are listed in the OJEC by the European Commission prior to their operation; the activities of the Notified Bodies are a matter for Member States, as they are appointed under their authority. While the Notified Body has various responsibilities under the Directive, the manufacturer always remains responsible for the compliance of the equipment. 8

T0700 D. Protection methods in potentially explosive atmosphere Protection methods are to be implemented so that equipment and electrical components can be used in a potentially explosive atmosphere. Safety methods: Protection types Ex d: flame-proof Ex e: increased Ex i: intrinsic Ex m, Ex o, Ex p or Ex q Principles Contains the explosion in an appropriate explosion proof housing. Increases the reliability of the electrical components so that sparks or arcs cannot appear. Ex e voltage to apply is determined through severe limitations in the calculations of clearance and creepage distances. Reduces the energy to a very low energy level so that even sparks or arcs cannot ignite an explosion atmosphere. Prevent contact between the electrical component and the explosive atmosphere pplications for Ex d, Ex e and Ex i protection types Flameproof protection Ex d mong the several protection methods, flameproof "Ex d" protection method is the most ancient and therefore represents the protection method the most implemented. Non-TEX certified terminal blocks could be installed in a flameproof enclosure: the protection against explosion propagation is ensured by the enclosure not by the terminal block itself. However, as it requires a very specific design (the enclosure must be capable of withstanding a possible internal explosion), this solution appears over costly for terminal block installations. Intrinsic protection Ex i Intrinsic protection is a common method of protection for instrumentation and control; it applies to an entire circuit. Blue is generally the colour code for the intrinsic circuit components. It is the only protection method that can be implemented in zone 0 or 20 (permanent presence of explosive atmosphere), as the allowed voltage and current are extremely low. Voltage and current calculations are necessary to ensure that the circuit composed of its several components will operate safely. Increased protection Ex e Increased protection remains the best economical and technical choice for a safe use of terminal blocks in hazardous locations. BB TEX terminal block range, certified in increased safety, requires a high level of construction technology and do not require an explosion proof (Ex d) enclosure to operate safely in an explosive atmosphere. Please note that the enclosure containing the terminal blocks must offer a Dust protection (IP6X minimum) and be Ex e certified itself in order to determine the maximum surface temperature in the housing (calculations consider the number of terminal blocks in the housing and current to be applied) BB supplies intrinsic and increased protection certified terminal blocks, even if the intrinsic certification is not mandatory for components. The reasons are added benefits for our customers: it allows us to supply you with the TEX appropriate group and category marked on the block as well as the Ex i necessary voltage calculations, which have been confirmed by a notified body. 0
T0700 D. Protection methods in potentially explosive atmosphere (cont.) Terminal blocks use Here below are the protection methods, for which the TEX certification applies to terminal blocks. (*certification is not mandatory for components used in intrinsic protection only) Normes EN Méthodes de protection Symbole Concepts EN 60079-0 General rules EN 60079-7 Increased safety e No sparks or arcs in normal use. Control of dangerous temperature levels : because they can generate arcs or sparks in normal use, switch or fuse terminal blocks cannot be classified in increased protection. EN 50020 Intrinsic safety i Control of sparks, arcs or overheating through a very low energy level
T0700 E. Entrelec terminal blocks & accessories certification TEX Terminal block range certification level Ex e IM2 and II2GD and Ex i IM and IIGD The BB attestation of conformity guarantees the end user the conformity of the product in regards with the TEX 95 directive and applicable standards. It is generic to the whole TEX range. ccessory certification Entrelec terminal block accessories are automatically TEX certified. Please refer to the catalogue pages for the accessory list per terminal block. Some accessories like jumper bars or shielding connectors may declass the terminal block voltage. The detailed voltage is not indicated in the EC type examination certificate -the examination certificate, issued by the notified body, is meant to establish the TEX terminal block conformity only-.

SN 46 227 R2500 Thermocouple terminal blocks BB Entrelec's MTC 6.Ex thermocouple terminal block provides an interface for connecting thermocouple wire with virtually no loss of signal integrity. The interface design ensures positive wire continuity and allows selection and inventory of one terminal block for all thermocouple material. Figure : MTC 6.Ex with shield connector The thermocouple principle is based on the reaction of different metals to temperature. When thermocouple wires are terminated or connected, the "metal balance" must be maintained. The introduction of a foreign material (such as copper) results in loss of signal strength and integrity. When running extended or intermittent lengths of thermocouple wire, to a measurement instrument, two solutions are available :. When signals are carried over a long distance, a thermocouple transmitter is required. The thermocouple signal, in millivolts (mv), is converted to a milliampere (m) signal (i.e. 4-20 m) for ease of transmission. 2. When thermocouple wire is of insufficient length, termination and interconnection, using terminal blocks, will extend its length.

This requires inventory of many different terminal block types. BB Entrelec's MTC 6.Ex terminal block adapts to all thermocouple material. This "neutral" method of connection limits the introduction of foreign materials to an insignificant level. The thermocouple wire insulation is stripped (3 mm maximum) and the bare wires are superimposed on one another. The thermocouple wires are in contact over their complete 3 mm length and tightened at two points by round tip screws (see figure 2). 2 The screws, made of plated brass, have only a mechanical function, that of holding the wires together with a point contact. Thus, the pressure points are not relevant in the connection environment. One thermocouple lead connects through one terminal block. The MTC 6 requires only 6 mm of space, allowing 50 terminals per foot of rail. Thermocouple shield wire connector bar R R See markers section RC65 - RC60 The MTC 6.Ex can be field of factory equipped with a shield connector bar (see figure ). This bar, made of brass, tin coated mounts in the lower part of the terminal block. It ensures the continuity of the thermocouple wire shield through the terminal block or to ground with no additional spacing. Other accessories see section accessories 20
