23、asuring gas concentrations and other combustion parameters, as used in the installation and maintenance of heating appliances. It forms a specification for portable electrical apparatus designed to measure combustion flue gas parameters of heating appliances, and includes the following parts under t
24、he generic title Specification for portable electrical apparatus designed to measure combustion flue gas parameters of heating appliances: Part 1: General requirements and test methods; Part 2: Performance requirements for apparatus used in statutory inspections and assessments; Part 3: Performance
25、requirements for apparatus used in non-statutory servicing of gas fired heating appliances. EN 50379-1 specifies general requirements for the construction, testing and performance of portable spot reading apparatus designed to give an assessment of specific combustion flue gas parameters, such as co
26、ncentrations of gaseous compounds, temperature and/or pressure, to check the combustion performance of heating appliances for domestic residential and commercial applications, using commercially available fuels. EN 50379-2 is for apparatus intended to be used for statutory measurement. In several Eu
27、ropean countries, legal requirements exist for the performance of heating appliances (see Annex A). Authorised inspectors use these apparatus to measure the flue gas parameters, in order to test compliance with national regulations. Due to the legal consequences resulting from the measurement, there
28、 are strict requirements regarding the measuring uncertainty of these apparatus, and EN 50379-2 therefore includes maximum values for measuring uncertainty. Tests with real flue gases form a key part of the verification of the performance of the apparatus for statutory measurement. The measuring unc
29、ertainty has to be justified by internationally accepted methods over the whole measuring range. The determination of measuring uncertainty is described in Annex C. EN 50379-3 is for apparatus intended to be used for non-statutory applications. There are reduced performance requirements, because the
30、 apparatus are designed to decide whether maintenance for a gas fired appliance is required, and for adjusting the appliance during maintenance. There will be no determination of the measuring uncertainty for the apparatus. BS EN 50379-1:2012EN 50379-1:2012 - 6 - 1 Scope This European Standard cover
31、s apparatus for measuring gas concentrations and other combustion parameters, as used in the installation and maintenance of heating appliances. Such apparatus may be used for testing the performance of appliances for different types of fuels, either by the installer, maintenance engineer or inspect
32、or. The apparatus may consist of different functional modules, which may be tested separately for complying with this standard and will be combined in different ways according to the different applications. This part of EN 50379 specifies the general requirements and is supplemented by the requireme
33、nts in EN 50379-2 and/or EN 50379-3. This European Standard specifies general requirements for the construction, testing and performance of portable spot reading apparatus designed to give an assessment of specific combustion flue gas parameters, such as concentration of gaseous compounds, temperatu
34、re and/or pressure, to check the combustion performance of heating appliances for domestic residential and commercial applications, using commercially available fuels. This European Standard excludes apparatus for continuous emission, safety monitoring and control, and use in vessels with an interna
35、tional load line. NOTE 1 When this apparatus is used in industrial premises national regulations may apply. NOTE 2 Apparatus may contain functional modules which are not covered by this standard e.g. measurement of smoke spot number (see EN 267:2009+A1:2011, Annex A) and/or measurement of indoor amb
36、ient air (see EN 50543). 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
