Furthermore, it shall also have been determined that, by enhancing or increasing the safety of certain vulnerable parts, the required level of protection is ensured against the possibility of ignition sources occurring. 4.2 General requirements for equipment All parts shall be capable of functioning in conformity with the operational parameters established by the manufacturer throughout their expected lifetime. They shall be sufficiently firm and durable to withstand the mechanical and thermal stresses to which they are intended to be subjected.
This also applies to interconnecting parts of equipment including joints (e.g. cemented, soldered or welded joints). 4.3 Ingress Protection 4.3.1 General The degree of ingress protection (IP) provided by the outer enclosures of equipment depends upon its intended duty and the type of environment it is designed to be used in. An appropriate rating, according to IP category 1, as specified in 13.4 of EN 60529:1991, shall be determined as part of the ignition hazard assessment (see 4.1) and shall be able to prevent foreign objects and/or water entering the equipment which could: 1) Increase the probability of ignition, by for example, allowing combustible dust, with a lower ignition temperature than the potentially explosive atmosphere, to form a layer on hot internal components or parts of the equipment; and/or 2) make contact with moving parts, resulting in the creation of an effective ignition source. SIST EN 13463-5:2011
NOTE An enclosure can be required for other safety reasons, e.g. IP 2X to prevent parts of the body coming into contact with rotating parts. 4.4 Seals for moving parts 4.4.1 Unlubricated gaskets, seals, sleeves, bellows and diaphragms
Unlubricated gaskets, seals, sleeves, bellows and diaphragms shall not become an effective ignition source, e.g. If there is a risk of mechanically generated sparks which can become an effective ignition source, light metals shall not be used (see EN 13463-1). NOTE Sleeves made e.g. of elastomeric material, PTFE or similar material, graphite and ceramics might be suitable. Non-metallic materials shall be resistant to distortion and degradation without reducing the effectiveness of explosion protection (see EN 13463-1). 4.4.2 Stuffing box seals (packed glands) Stuffing-box seals (packed glands) shall only be used if a temperature rise above the permitted maximum surface temperature can be excluded. NOTE Otherwise a device to monitor temperatures and switch off equipment should be applied (see EN 13463-6). 4.4.3 Lubricated seals Seals which normally require the presence of a replenishable lubricant to prevent hot surfaces occurring at their interface with equipment parts a) shall be designed to ensure the sufficient presence of lubricant; or
b) shall be protected by one of the following means: 1) provision of an effective means to monitor the continued presence of the lubricant; or 2) provision of a temperature detection device to warn of increasing temperatures; or SIST EN 13463-5:2011
NOTE 1 In the case of parts protected by fluids see EN 13463-8. NOTE 2 See 4.6, Note 2 for the precautions which may be adopted for the purpose of expected malfunction. SIST EN 13463-5:2011
Where equipment is designed to process liquids as part of its duties and the presence of the process liquid is essential for the purpose of lubrication, cooling, quenching, or ignition prevention, this shall be stated in the instructions for safe use, as required by EN 13463-1. The instructions for safe use shall state the correct way for bringing a self priming pump in operation. 6 Requirements for bearings 6.1 General Bearings are basically divided into three types, sliding plane motion, sliding rotary motion and rolling element. When assessing bearings, as part of the ignition hazard assessment required by EN 13463-1, the following (which is not a definitive list) shall be taken into account: the bearing shall be designed for the equipment’s intended duty e.g. speed, temperature, loading and variations of speed and loading; the bearing’s basic rated life. As described in ISO 281 for rolling element bearings. (see also Note 1 below); the proper fit of the bearings in their housing and on the shaft (tolerances, roundness and surface quality), taking into consideration the vertical and axial loads on the bearing with respect to shaft and housing; the correct alignment of the bearings; the axial and radial loading of the bearings caused by thermal expansion of the shaft and the housing under the most severe operating conditions; protection of the bearing from ingress of unintended liquids and solids, if necessary to avoid premature failure; protection of the bearing from electrical currents, including stray circulating currents (which can cause, for example, incendive sparking, or spark erosion leading to premature failure, at the point of contact between the ball and ball race of a ball bearing). If bearings act as an insulator, constructive measures, e.g. earthing or bonding, shall be taken, so that the isolation of parts of the equipment is avoided (see EN 13463-1:2009, 6.7.2); the provision of adequate lubrication, according to the lubricating regime necessary for the type of bearing (e.g. for sliding bearings, boundary lubrication, mixed film, or full film hydrodynamic lubrication are the most commonly used regimes); SIST EN 13463-5:2011
The requirements of 5.3 apply. 6.3 Chemical compatibility
Bearings shall be made of materials resistant to the liquids, or vapours, in which they are intended to be used. Similarly, the material used in the construction of the bearing, including any bearing cages, shall be resistant to any liquids or solvents which can come into contact with them. Particular attention shall be given to the possibility of swelling of non-metallic parts. Where liquids or vapours can dissolve in the lubricant of the bearings, the lubricant shall remain "fit for purpose" even in this condition. SIST EN 13463-5:2011
b) synchronous (timing) belt drives, with positive interaction between belt teeth and pulley grooves such that friction heat build up does not normally occur. 7.2.2 Power transmission belts shall not be capable of developing an incendive electrostatic discharge during operation, see Annex B for conductivity criteria and measurement requirements. NOTE 1 ISO 1813 - friction belt drives, and ISO 9563 - synchronous belt drives, specify methods of measuring belt electrical resistance, and give resistance values intended for use where belt drives work in explosive atmospheres. However, the state of the art is set out in CLC/TR 50404. The Technical Report particularly gives advice on the use of belt drives for particular categories and explosive atmospheres.
Where the electrical resistance of a belt is known to increase over time in normal service, the manufacturer shall specify a time period for re-testing or replacement of the belt.
NOTE 2 Whilst conductive of electrostatic charges, belts should not be considered a suitable earth path between the drive and driven pulleys, for lower voltage potentials.
7.2.3 For drives which could cause surfaces to exceed the maximum surface temperature if the belt becomes slack or slips on the pulley, the correct belt tension shall be maintained. NOTE Devices used to ensure correct belt tension can also serve to detect broken belts. 7.2.4 With drives which could cause surfaces to exceed the maximum temperature if they run out of alignment, true alignment shall be maintained (see 7.2.3). NOTE A correctly designed and installed belt drive, operating near the limit of its capability, may produce surface temperatures in normal running of up to: Friction drives
50 K above ambient Synchronous drives
25 K above ambient. Temperature rises greater than the above will likely reduce the working life of belts. 7.2.5 The supporting frame, chassis, or structure, of equipment containing belt(s) shall be constructed of electrically conducting material and shall be so arranged as to provide a leakage path to earth for any static electricity which occurs on the belt(s). The frame, chassis or structure includes the driving pulley or drum and any idler pulleys or rollers associated with the belt drive. Specific electrical bonding between the separate parts and earth shall be provided where the electrical resistance of the leakage path to earth exceeds 1 MΩ. SIST EN 13463-5:2011
7.3 Flexible couplings 7.3.1 When operated within their design parameters, flexible couplings shall not generate hot surfaces, which exceed the permitted maximum surface temperature, nor disintegrate in a way which would create the risk of an ignition source, through for example contact between moving metal parts. Manufacturers shall define the design parameters using established calculation methods or testing.
NOTE Suitable calculation methods are given in DIN 740-2. 7.3.2 Flexible couplings shall be of a design and built of materials such as to exclude the possibility of an incendive electrostatic discharge. NOTE This does not necessitate an electrical conductive path (through the flexible coupling) between the coupled shafts unless specified as necessary to complete an earth path from other parts of the coupled machinery. 7.3.3 Where flexible couplings employing non-metallic elements are used to separate metallic components which could otherwise contact and cause incendive sparks, user instructions shall specify the installation and maintenance procedures needed to prevent metal/metal contact during normal use. 7.3.4 Flexible couplings designed to accommodate shaft misalignment shall be installed such that misalignment does not exceed the manufacturers’ maximum values, with due regard to any foreseeable movement or flexure of machinery after installation. In particular, the bores in the hubs shall be sufficiently accurate to ensure concentric running of coupling hubs, and of appropriate diameter tolerance to help ensure secure and accurate shaft fixing. 7.3.5 The manufacturers instructions for safe use shall include maximum torque, maximum rotational speed, limits on angular and linear alignment deviations, the temperature rise of polymeric or metal spring components during normal operation at the limiting parameters, and any other information necessary for safe use. 7.4 Chain drives Chain drives shall comply with the requirements of Clause 5.
Chain drives operating at speeds greater than 1 m/s, and containing a potential ignition source (identified by the ignition hazard assessment required by EN 13463-1), shall be fitted with means to ensure continuous positive engagement of the chain with its associated sprocket. Where this is not possible, it shall be fitted with a device that removes the driving power to the drive sprocket in the event of the chain breaking, becoming disengaged, or slackening beyond a limit specified by the information for use (see EN 13463-6). 7.5 Other Drives Other drives shall fulfil the requirements set out in Clause 5. SIST EN 13463-5:2011
NOTE 1 For Group I equipment this can be achieved by using a liquid with a fire resistance rating of at least "2", when tested in accordance with the "Community of Six Spray ignition Test" and a persistence of flame not exceeding 30 s, when tested in accordance with the "Wick test", as described in 3.1.1 and 3.2 of the European Safety and Health Commission for Mining and Other Extractive Industries (SHCMOEI) document - Requirements and tests applicable to fire-resistant hydraulic fluids used for power transmission and control (Hydrostatic and Hydrokinetic)", 1994 [1].
NOTE 2 National legislation in member states can require the use of different fire resistant fluids in certain hydraulic systems. 7.6.6 Air compressors used for pneumatic equipment shall: incorporate a filter on the intake system to prevent the ingress of dust or similar foreign material into the parts where compression takes place; contain only lubricants which are resistant to carbonisation. NOTE 1 Carbonisation of compressor lubricant (caused by exposure to elevated temperatures) results in the formation of oily carbon deposits in the compressor delivery which can cause it to overheat and explode. NOTE 2 For fluids operating at high pressure (e.g. inside compressors) allowance should be made for the fact that the ignition temperature is lowered by increased operating pressure. 7.7 Clutches and variable speed couplings 7.7.1 Clutches and couplings, shall be arranged or monitored (see EN 13463-6) so that no fixed or moving part that is exposed to the potentially explosive atmosphere exceeds the maximum surface temperature of the equipment. In the case of plastic or other non-metallic parts of a clutch or coupling, their material or arrangement shall exclude the possibility of an incendive electrostatic discharge. NOTE Examples of the above types of clutch and coupling are friction plate clutches, bell type centrifugal clutches, fluid couplings and scoop-controlled fluid couplings. 7.7.2 During the period of full engagement, there shall be no slipping, or similar relative movement between the input and output mechanisms likely to cause a hot surface exceeding the maximum surface temperature. NOTE The above requirements can be achieved by one or more of the following preventative methods (see EN 13463-6): SIST EN 13463-5:2011

Its relevance in contemporary industrial applications cannot be overstated, given the increasing focus on workplace safety and adherence to European regulations. The standard effectively bridges the gap between safety protocols and practical applications, underlining its fundamental role in promoting a safer working environment in potentially hazardous situations.
SIST EN 13463-5:2011は、潜在的に爆発性雰囲気で使用することを目的とした非電気機器に関するヨーロッパ標準であり、特に構造的安全性「c」によって保護される機器の設計と構造に関する要件を規定しています。この標準は、EN 13463-1の要件を補完するものであり、EN 13463-1に従って構築された機器にも完全に適用される内容となっています。 この標準の主な強みは、爆発性雰囲気における機器の安全性を高めるための明確で具体的な基準を提供している点です。特に、標準はさまざまな点火保護のタイプを組み合わせることを許可しており、これにより機器の設計者や製造者は、特定の点火危険評価に基づいて、最適な保護手段を選択することができます。この柔軟性は、特にグループI、カテゴリーM2、またはグループII、カテゴリー1および2の機器において大きな利点といえます。 さらに、標準は、設計者が考慮すべき点火源についても明示されており、実際の安全性向上に寄与しています。ほとんどのカテゴリー3機器では、EN 13463-1の要件を満たすだけで十分ですが、一部のカテゴリー3機器は、点火危険評価で特定された点火源に対する欧州標準の要件を満たさなければならないこともあるため、この標準は、広範囲の機器の設計および使用において非常に重要です。 総じて、SIST EN 13463-5:2011は、潜在的に爆発性のある環境での非電気機器の設計および建設における重要なガイドラインを提供しており、業界全体で公共の安全を確保する上で欠かせないものといえます。
