(Main)Electrical apparatus for the detection of flammable gases in household premises - Part 1: Test methods and performance requirements
Electrical apparatus for the detection of flammable gases in household premises - Part 1: Test methods and performance requirements
This document specifies general requirements for the construction, testing and performance of electrically operated apparatus for the detection of flammable gases, designed for continuous operation in a fixed installation in household premises. The apparatus can be mains or battery powered. Additional requirements for apparatus to be used in recreational vehicles and similar premises are specified in EN 50194-2. NOTE For caravan holiday homes EN 50194-1 applies. This document specifies four types of apparatus to warn and/or alarm in the event of an escape of town gas, natural gas or liquefied petroleum gas (LPG), Hydrogen and flammable refrigerant gases: — Type A apparatus – provides a visual and audible alarm and an executive action in the form of an output signal that can actuate directly or indirectly a shut-off device and/or other ancillary device in the event of an escape of town gas, natural gas (LNG) liquefied petroleum gas (LPG) and Hydrogen gases; — Type B apparatus – same as Type A but provides a visual and audible alarm only; — Type C apparatus – provides a visual and audible alarm and an executive action in the form of an output signal that can actuate directly or indirectly a shut-off device and/or other ancillary device in the event of an escape of flammable refrigerant gas A2L, A2 or A3 as classified in other International Standards, e.g. ISO 817; — Type D apparatus – intended to be installed where there can be a source of danger to the public, designed for continuous operation in fixed installations in non-classified explosive atmosphere premises (where the requirements for electrical Ex-safety are not requested). Intended for any flammable gases. Typically Type D apparatus are available with analogue or digital output, designed as detection system. These systems are regularly maintained by competent persons and/or have a protection of IP44 or higher. For type D apparatus, EN 60079-29-1 is applied. See Annex C for further clarification on the apparatus types and their application. NOTE Apparatus complying with this document is not considered suitable for installation in potentially explosive atmospheres, in which case the EN 60079 series applies. NOTE Apparatus complying with EN 60079-29-1 will not necessarily comply with this document. This document 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 used for breath alcohol measurement; — apparatus intended for the direct measurement of automotive exhaust gases; — apparatus intended for use in industrial environments.

Električne naprave za zaznavanje vnetljivih plinov, ki se uporabljajo v gospodinjskih okoljih - 1. del: Preskusne metode in zahtevane lastnosti
Z revizijo standarda EN 50194-1 naj se vključi tudi gospodinjska uporaba in na splošno vse, kar ni zajeto v standard IEC-EN 60079-29-1, tj. nerazvrščena območja. S tem se bo ocenilo, ali naj se poleg detektorjev (običajno prostostoječih) upoštevajo tudi senzorji ali modul, ki ga je mogoče brez ohišja vgraditi v nekatere naprave.
Na koncu naj se v to novo revizijo vključi sklic na standard skupine, ki je bil v preteklih letih oblikovan za področje zaznavanja plinov in ni vključen v sedanji standard.
