EN 50270:2015 includes the following si
16、gnificant technical changes with respect to EN 50270:2006: requirements updated according to EN 613261:2013; aspects related to functional safety considered; several requirements of EN 6132632 implemented; the hierarchical level between criteria B and C re-inserted by modifying the requirements for
17、B; Tables 1 to 4 updated according to above mentioned points; Table 5 modified according to new and updated performance standards; Table 5 now includes also the requirements for criterion B. This document has been prepared under a mandate given to CENELEC by the European Commission and the European
18、Free Trade Association, and supports essential requirements of EU Directive(s). For the relationship with EU Directive(s) see informative Annex ZZ, which is an integral part of this document. BS EN 50270:2015EN 50270:2015 - 4 - 1 Scope This European Standard specifies requirements for the electromag
19、netic compatibility (EMC) for electrical apparatus for the detection and measurement of combustible gases, toxic gases or oxygen which are subject to the performance standards for gas detection apparatus, for example EN 45544 (all parts), EN 50104, EN 50194 (all parts), EN 50291 (all parts), EN 5037
20、9 (all parts), EN 50543, EN 50545-1, EN 60079-29-1 or EN 60079-29-4. NOTE For the purpose of this standard the word toxic covers very toxic, toxic, harmful, corrosive, irritating, sensitising, carcinogenic, mutagenic and teratogenic. This European Standard applies to apparatus intended for use in re
21、sidential, commercial and light-industrial environments as well as to apparatus intended for use in industrial environments. The apparatus may be AC-, DC- or battery powered. This European Standard is also applicable to apparatus which is intended for use in hazardous areas which may contain explosi
22、ve or potentially explosive atmospheres. It covers only normal operation and does not cover safety requirements related to EMC phenomena. This standard is a product standard which is based on the product family standard EN 61326-1. This product standard takes precedence over the product family stand
23、ard and over generic standards. This standard applies to electrical apparatus for the detection and measurement of combustible gases, toxic gases or oxygen that include functions specified by the manufacturer as being safety functions and can include functions specified as not being safety functions
24、. All performance standards for the detection and measurement of combustible gases, toxic gases or oxygen include the minimum requirements for functional safety specified in EN 50271. There are also gas detectors and gas detection systems which are intended to be used with safety integrity levels SI
25、L 1 to SIL 3 according to EN 50402 and EN 61508 (all parts). For functional safety in industrial applications, this standard has taken into account those aspects of EN 6132632 relating to the measuring and warning function of the apparatus defined as safety function. This standard specifies requirem
26、ents for immunity tests in relation to continuous and transient, conducted and radiated disturbances, including electrostatic discharges, and also for emission tests. The test requirements are specified for each port considered. Apparatus falling within the scope of this European Standard is classif
27、ied as follows by the following types. Type 1: apparatus intended for use in residential, commercial and light-industrial environments, as described in EN 61000-6-1 and EN 61000-6-3. Type 2: apparatus intended for use in industrial environments, as described in EN 61000-6-2 and EN 61000-6-4. Apparat
28、us of type 1 where the manufacturer claims a safety integrity level should be considered as type 2 apparatus with regard to immunity requirements. This European Standard does not apply to any of the following: apparatus intended for the detection of dusts or mists in air; scientific or laboratory ba
29、sed apparatus used only for analysis or measurement; apparatus used exclusively for process measurement purposes; apparatus for medical purposes; apparatus used for breath alcohol measurement apparatus intended for the direct measurement of automotive exhaust gases.
