17、be withdrawn (dow) 2016-07-15 This document supersedes EN 50292:2001. EN 50292:2013 includes the following significant technical changes with respect to EN 50292:2001 (various minor changes have also been made). Title and definitions are revised to be more general, i.e. to cover domestic premises, b

18、oats and caravans. This is a result of the splitting of EN 50291 into EN 50291-1 and EN 50291-2. In 4.3.1 of EN 50292:2001, incorrect terminology “warm air systems“ is replaced by “ducted air heaters“ (in 4.3.2 of EN 50292:2013). In 4.7, a more general title replaces the previous one as CO migration

19、 applies not only to multi-occupancy and multi-storey buildings but also to any premises connected to other premises, such as semi-detached and terrace premises, where the migration of CO is possible. In 5.2.1 and 5.2.2, the use of caravans and boats is included in installation/location information.

20、 In 5.3, an additional type of apparatus is added, capable of identifying lower concentrations of CO than would be needed to trigger an alarm. Such features are available in certain products, and may be useful to some at-risk groups, especially people who have respiratory health issues. In 6.2, the

21、text is modified so that triggering a shut-off valve should be on the main gas supply, ideally at the gas meter/cylinder outlet, so that the entire installation is isolated (and not only individual appliances as stated in the previous version), as the source may not be that appliance. In 6.4, the te

22、xt is modified to state that it is more important that the gas supply is isolated rather than the electrical supply. There is no need to make an exception for a gas appliance with an electrical connection. The carbon monoxide detection apparatus should not be used to operate the mains electrical swi

23、tch, since such action may create unnecessary hazard for occupants of the premises. A new subclause 7.1 “Use of alarm“ is added. It includes the requirement to advise the user that a CO alarm does not replace the correct installation, commissioning and regular maintenance by a competent person. This

24、 is required in the instruction booklet by EN 50291-1:2010, 4.7.4, item n. NOTE This was already stated in the introduction to EN 50292 but it is emphasised in the new 7.1. In 7.5, text relating to hydrogen interference is added. In Clause 8, recommendation to isolate the emergency control valve for

25、 gas installations is added. In Clause 8, text advising that the Gas Emergency Service Provider should be contacted in the first instance is added. A new Figure A.1 is added, showing CO-concentration and exposure time curves for various COHb levels including 2,5 % COHb (the protection level recommen

26、ded by WHO). In A.2, text about health effects on vulnerable groups, derived from WHO, is added. Figure B.1 is modified to illustrate how alarm set points in EN 50291-1 align with the 2,5 % and 5 % COHb curves, providing a more practical rationale rather than the previous theoretical one.

27、2:2013EN 50292:2013 - 4 - Introduction This European Standard is intended to be a guide for people who, in the course of their professional activities, are required to install apparatus for the detection of carbon monoxide (CO) in domestic premises. It is also aimed at anyone who might supply such d

28、etectors to members of the public for subsequent installation according to national regulations, so that advice may be given based on good engineering practice. Apparatus for the detection of carbon monoxide are not a substitute for good installation and regular servicing of fuel burning appliances

29、or regular cleaning of chimneys, although they may provide an added margin of reassurance for users. Domestic carbon monoxide detectors with or without some form of executive function may overcome fears of fuel safety and may be particularly beneficial in certain circumstances. It is necessary to un

30、derstand that carbon monoxide toxicity may have different consequences according to the physical condition of the individual. Thus, a carbon monoxide detector designed according to EN 50291 series may not fully safeguard individuals with specific medical conditions. Carbon monoxide detectors are not

31、 intended to be used as an alternative to a smoke alarm. BS EN 50292:2013- 5 - EN 50292:2013 1 Scope This European Standard serves as a guide on the selection, installation, use and maintenance of apparatus for the detection of carbon monoxide, intended for continuous operation in a fixed installati

32、on in domestic premises, caravans and boats. This guide is intended to cover any type of domestic or residential accommodation, including leisure accommodation vehicles such as touring and static caravans, and motor homes; and recreational craft such as canal barges. Some static caravans are used as

33、 permanent dwellings, in such cases EN 50291-1 is appropriate. For all other types of caravan, EN 50291-2 is appropriate. This guide should be read in conjunction with EN 50291-1 and EN 50291-2 together with any additional relevant national or local regulations. This European Standard refers to the

34、installation of two types of apparatus: a) Type A apparatus, to provide a visual and audible alarm and an executive action in the form of an output signal that can be used to actuate directly or indirectly a ventilation or other ancillary device; b) Type B apparatus, to provide a visual and audible

35、alarm only. This European Standard excludes apparatus for the detection of combustible gases (see EN 50244) and for industrial installations or commercial premises. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable

46、h of 24 m as specified in Directive 94/25/EC, which is intended for sports or leisure purposes BS EN 50292:2013- 7 - EN 50292:2013 4 Sources of carbon monoxide 4.1 General information Carbon monoxide is a colourless, odourless, non-irritating gas which is classified as a chemical asphyxiant, whose t

47、oxic action is a direct result of the hypoxia produced by a given exposure (see Annex A and Annex B). 4.2 Normal exposure levels Carbon monoxide can be generated within the home or enter from outside. The normal average background levels of carbon monoxide in domestic premises, measured over periods

48、 of 1 h to 24 h, are less than 10 ppm. In cases of climatic inversion, higher levels of carbon monoxide are possible. 4.3 Burning of carbonaceous materials for heating and cooking 4.3.1 General Most of the carbon monoxide in the environment is produced during combustion of carbonaceous material, e.g

49、. solid fuels (such as coal, coke and wood), liquid fuels (such as oil and petrol) and gaseous fuels (such as natural gas, town gas and liquefied petroleum gas (LPG). It should be noted that town gas is still used in some EU countries and it can contain a significant proportion of carbon monoxide prior to combustion. The proportion and constituents of the combustion products from carbonaceous fuels will depend on the particular fuel and the combustion conditions. Varying concentrations of carbon monoxide are produced from most com
