17、icting with this document have to be withdrawn (dow) 2017-10-20 This document supersedes EN 50270:2006. EN 50270:2015 includes the following significant technical changes with respect to EN 50270:2006: requirements updated according to EN 613261:2013; aspects related to functional safety considered;
18、 several requirements of EN 6132632 implemented; the hierarchical level between criteria B and C re-inserted by modifying the requirements for 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
19、the requirements for criterion B. This document has been prepared under a mandate given to CENELEC by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For the relationship with EU Directive(s) see informative Annex ZZ, which is
20、an integral part of this document. BS EN 50270:2015EN 50270:2015- 4 - 1 Scope This European Standard specifies requirements for the electromagnetic compatibility (EMC) for electrical apparatus for the detection and measurement of combustible gases, toxic gases or oxygen which are subject to the perf
21、ormance standards for gas detection apparatus, for example EN 45544 (all parts), EN 50104, EN 50194 (all parts), EN 50291 (all parts), EN 50379 (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, c
22、orrosive, irritating, sensitising, carcinogenic, mutagenic and teratogenic. This European Standard applies to apparatus intended for use in residential, commercial and light-industrial environments as well as to apparatus intended for use in industrial environments. The apparatus may be AC-, DC- or
23、battery powered. This European Standard is also applicable to apparatus which is intended for use in hazardous areas which may contain explosive or potentially explosive atmospheres. It covers only normal operation and does not cover safety requirements related to EMC phenomena. This standard is a p
24、roduct standard which is based on the product family standard EN 61326-1. This product standard takes precedence over the product family standard and over generic standards. This standard applies to electrical apparatus for the detection and measurement of combustible gases, toxic gases or oxygen th
25、at include functions specified by the manufacturer as being safety functions and can include functions specified as not being safety functions. All performance standards for the detection and measurement of combustible gases, toxic gases or oxygen include the minimum requirements for functional safe
26、ty specified in EN 50271. There are also gas detectors and gas detection systems which are intended to be used with safety integrity levels SIL 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 aspe
27、cts of EN 6132632 relating to the measuring and warning function of the apparatus defined as safety function. This standard specifies requirements for immunity tests in relation to continuous and transient, conducted and radiated disturbances, including electrostatic discharges, and also for emissio
28、n tests. The test requirements are specified for each port considered. Apparatus falling within the scope of this European Standard is classified as follows by the following types. Type 1: apparatus intended for use in residential, commercial and light-industrial environments, as described in EN 610
29、00-6-1 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. Apparatus of type 1 where the manufacturer claims a safety integrity level should be considered as type 2 apparatus with regard to immunity requirements. This Europe
30、an Standard does not apply to any of the following: apparatus intended for the detection of dusts or mists in air; scientific or laboratory based apparatus used only for analysis or measurement; apparatus used exclusively for process measurement purposes; apparatus for medical purposes; apparatus us
31、ed for breath alcohol measurement apparatus intended for the direct measurement of automotive exhaust gases.
