19、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 the generic title Specification for portable electrical apparatus designed to measure com
20、bustion 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 requirements for apparatus used in non-statutory servicing of gas fired heating applianc
21、es. 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 concentration of gaseous compounds, temperature and/or pressure, to check the combustion p
22、erformance 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 European countries, legal requirements exist for the performance of heating appliances. Auth
23、orised inspectors use these apparatus to measure the flue gas parameters, in order to test the compliance with national regulations. Due to the legal consequences resulting from the measurement there are strict requirements regarding the measuring uncertainty of these apparatus. Therefore EN 50379-2
24、 includes maximum values for measuring uncertainty of the apparatus. Tests with real flue gases form a key part of the verification of the performance of the apparatus for statutory measurement. The measuring uncertainty has to be justified by internationally accepted methods over the whole measurin
25、g range. EN 50379-3 is for apparatus intended to be used for non-statutory applications. There are reduced performance requirements, because the apparatus are designed to decide whether maintenance for a gas fired appliance is required, and for adjusting the appliance during maintenance. There will
26、be no determination of the measuring uncertainty for the apparatus. BS EN 50379-3:2012 5 EN 50379-3:2012 1 Scope This European Standard covers apparatus designed for checking the performance of heating appliances by measuring flue gas parameters of gas fired heating appliances for domestic residenti
27、al and commercial applications. 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. Part 1 of EN 50379 specifies the general requirements and is supp
28、lemented by the requirements in EN 50379-2 and/or EN 50379-3. This European Standard specifies the performance requirements of portable spot reading apparatus designed to detect specific combustion flue gas parameters, such as concentration of gaseous compounds, temperature and/or pressure, to be us
29、ed to decide if maintenance for the appliance is required and for adjusting the appliance during maintenance. This European Standard excludes apparatus for checking appliances using fuels other than gas, continuous emission, safety monitoring and control, and use in vessels with an international loa
30、d line. NOTE 1 When this apparatus is used in industrial premises, national regulations should be observed. 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
31、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.
