DIN EN 15233:2007 潜在易爆环境用保护系统的功能安全性评定方法

This European Standard provides guidance on the procedure and information required to allow functional safety assessment to be carried out for the design of protective systems. The purpose of this European Standard is to assist technical standardization committees responsible for specific families of protective systems in preparing safety standards. Such standards should be as homogenous as possible and should have the basic structure of functional safety assessment as it is stated in this standard. If there are no specific standards for a particular protective system, the manufacturer should use this standard for functional safety assessment of this protective system. In this procedure the following information is to be taken into account to ensure a sufficient level of functional safety: a) intended use, b) possible operating faults, c) reliability of protective systems, d) misuse which can reasonably be anticipated. A sufficient level of functional safety is characterized by the following objectives: 1) System can stop an explosion at a very early stage or reduce the impact of an explosion to an acceptable level. 2) In the event of faults, failures and/or interference~} the capacity to function remains effective by use e.g. of fail safe techniques or redundancy. This European Standard does not cover identification of possible ignition sources. NOTE I The identification of possible ignition sources is covered by EN 15198. This European Standard only deals with the functional behaviour of the protective system i.e. hazards caused by malfunctions, e.g. false activations are excluded. This European Standard specifies neither specific methods to analyse fault conditions, nor specific requirements for a given type of protective system (see EN 1127-1). It specifies the methodology of functional safety assessment. This European Standard provides advice for decisions to be made for all types of protective systems referred to in EU Directive 94/9/EC, but does not provide means to prove the conformity of a given type of protective systems. NOTE 2 Equipment is dealt with in EN 15198 owing to the fact that the procedure and information required to allow ignition hazard assessment is different from the procedure above.

DIN EN 15198:2007 潜在易爆环境中使用的非电气设备和部件的风险评估方法

This European Standard specifies basic methodology used in achieving safety of equipment for intended use in potentially explosive atmospheres. The provisions specified in this European Standard are intended for the designer. It also specifies a strategy for standard makers. This European Standard specifies the procedure and information required to allow ignition risk assessment to be carried out for the design of equipment or component. This European Standard provides advice for a decision to be made for the categorisation of equipment but does not provide means to prove the conformity of equipment categories. In this procedure the following information is to be taken into account: a) Possible occurrence of an explosive atmosphere inside the equipment or component or penetrating the equipment or component from the outside (in normal operation or during malfunctions) and the amount of explosive atmosphere involved leading to possible explosion impact inside of the equipment or component; b) equipment or components surrounded by an explosive atmosphere (in normal operation or during malfunctions); c) equipment or components wholly or partly surrounded by an explosive atmosphere considering also any explosive atmosphere in connection (in normal operation or during malfunctions); d) presence and likelihood (effectiveness) of ignition sources. The final objective is designing and manufacturing equipment or components intended for use in potentially explosive atmospheres. For this purpose equipment or components if necessary should be designed with adequate preventive and/or protective measures. This European Standard specifies neither specific methods of analysis associated with ignition risk assessment, nor specific requirements for a category of equipment. It describes the methodology of ignition risk assessment. This European Standard does not apply to equipment with a potentially explosive atmosphere inside under operating conditions, and without interfaces to an external potentially explosive atmospheres. This European Standard is applicable to all categories of equipment referred to in EN 13463-1. This ignition risk assessment procedure does not preclude the conditions prevailing in an installation where the equipment or component is put into operation by a user. NOTE Functional safety assessment of protective systems is covered by EN 15233.

NF S66-203:2007 尘埃积聚物自发着火性的测定

Determination of the spontaneous ignition behaviour of dust accumulations.

EN 15188:2007 尘埃积聚物自发着火性的测定

This European Standard specifies analysis and evaluation procedures for determining self-ignition temperatures (TSI) of combustible dusts or granular materials as a function of volume by hot storage experiments in ovens of constant temperature. The specified test method is applicable to any solid material for which the linear correlation of lg (V/A) versus the reciprocal self-ignition temperature 1/TSI (with TSI in K) holds (i.e. not limited to only oxidatively unstable materials). This European Standard is not applicable to the ignition of dust layers or bulk solids under aerated conditions (e.g. as in fluid bed dryer). This European Standard should not be applied to dusts like recognised explosives that do not require atmospheric oxygen for combustion, nor to pyrophoric materials. NOTE Because of regulatory and safety reasons “recognised explosives” are not in the scope of this European Standard. In spite of that, substances which undergo thermal decomposition reactions and which are not “recognised explosives” but behave very similarly to self-ignition processes when they decompose are in the scope. If there are any doubts as to whether the dust is an explosive or not, experts should be consulted.

Determination of the spontaneous ignition behaviour of dust accumulations

DIN EN 14491:2007 灰尘防爆通风保护系统

This European Standard specifies the basic requirements of design for the selection of a dust explosion venting protective system. The standard is one of a series including prEN 14797 Explosion venting devices and prEN 14460 Explosion resistant equipment. The three standards together represent the concept of dust explosion venting. To avoid transfer of explosions to other communicating equipment one should also consider applying prEN 15089 Explosion Isolation Systems. This European Standard covers: - vent sizing to protect an enclosure against the internal pressure effects of a dust explosion; - flame and pressure effects outside the enclosure; - recoil forces; - influence of vent ducts. This European Standard is not intended to provide design and application rules against effects generated by detonation reactions or runaway exothermic reactions. This European Standard does not cover fire risks arising from either materials processed, used or released by the equipment or materials that make up equipment and buildings. This European Standard does not cover the design, construction, testing and certification of explosion venting devices that are used to achieve explosion venting1).

DIN EN 14797:2007 防爆装置

This European Standard specifies the requirements for venting devices used to protect enclosures against the major effects of internal explosions arising from the rapid burning of suspended dust, vapour or gas contained within. It includes the requirements for the design, inspection, testing, marking, documentation and packaging. This European Standard specifies explosion venting devices which are put on the market as autonomous protective systems. Explosion venting devices are safety devices comprised of a pressure sensitive membrane fixed to and forming part of the structure that it protects, designed to intervene in the event of an explosion at a predetermined low pressure, to immediately open a vent area sufficient to ensure that the maximum pressure attained by the explosion within the enclosure does not exceed its designed resistance to pressure. The application and specification of explosion venting devices is outlined for dust explosion protection in EN 14491 and for gas explosion protection in prEN 14994. The use of venting devices according to this European Standard on pipelines and on applications other than described in EN 14491 or prEN 14994 needs to be carefully evaluated and where appropriate their suitability needs to be confirmed by tests. Flameless explosion venting devices avoid the breakthrough of flames into the surroundings. They are used to allow explosion venting in situations where the hazards of flames resulting from the venting action are not acceptable. Flameless explosion venting devices are treated in a separate standard. This European Standard does not cover details for the avoidance of ignition sources from detection devices or other parts of the venting devices.

BS EN 14460:2006 防爆设备

This standard specifies requirements for explosion-pressure-resistant and explosion pressure shock-resistant equipment. This standard is applicable to process vessels and systems. It is not applicable to individual items of equipment such as motors and gearboxes that may be designed to withstand an internal explosion, which is the subject of EN 13463-3. This standard is valid for atmospheres having pressures ranging from 800 hPa to 1100 hPa and temperatures ranging from - 20 °C to + 60 °C. This standard may also be helpful for the design, construction, testing and marking of equipment intended for use in atmospheres outside the validity range stated above, as far as this subject is not covered by specific standards. This standard applies to equipment and combinations of equipment where deflagrations may occur and is not applicable to equipment and combination of equipment where detonation may occur. This standard should not be used for offshore applications. It is essential that this standard be used for equipment made of metallic materials only.

1.1 This test method covers the determination of the minimum concentration of a dust-air mixture that will propagate a deflagration in a near-spherical closed vessel of 20 L or greater volume.Note 1The minimum explosible concentration (MEC) is also referred to as the lower explosibility limit (LEL) or lean flammability limit (LFL).1.2 Data obtained from this test method provide a relative measure of the deflagration characteristics of dust clouds.1.3 This test method should be used to measure and describe the properties of materials in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire risk assessment that takes into account all of the factors that are pertinent to an assessment of the fire hazard of a particular end use.1.4 The values stated in SI units are to be regarded as the standard.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 8 .
