EN 50270:1999

EN 50270:1999 is a standard published by CLC. Its full title is "Electromagnetic compatibility - Electrical apparatus for the detection and measurement of combustible gases, toxic gases or oxygen". This standard covers: 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. This standard applies to apparatus intended for use in the residential, commercial and light-industrial environment as well as to apparatus intended for use in the industrial environment. The apparatus may be a.c.-, d.c.- or 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. This standard specifies requirements for immunity tests in relation to continuous and transient, conducted and radiated disturbances including electrostatic discharges and also for emission tests. The requirements are specified for each considered port. These requirements have been selected so as to ensure an adequate level of compatibility for apparatus at the appropriate locations. The levels do not however cover extreme cases which may occur in any location but with an extremely low probability of occurrence. NOTE: In special cases situations will arise where the level of disturbance may exceed the levels specified in this standard, e.g. where an apparatus is installed in proximity to industrial, scientific or medical (ISM) equipment as specified in EN 55011 or where a hand-held transmitter is used in close proximity to an apparatus. In these instances special mitigation measures may have to be employed. Apparatus falling within the scope of this European Standard is classified as follows by the following types. Type 1: apparatus intended for use in the residential, commercial and light-industrial environment, as described in EN 50081-1 and EN 50082-1. Type 2: apparatus intended for use in the industrial environment, as described in EN 50081-2 and EN 50082-2. 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 based apparatus used only for analysis or measurement; apparatus used exclusively for process measurement purposes; apparatus for medical purposes; apparatus intended for the direct measurement of automotive exhaust gases
