Description of PD CLC/TS 50612:2016 2017

This Technical Specification provides guidance on the selection, use and maintenance of portable electrical apparatus conforming to EN 50379-1 [4] and EN 50379-2 [5] or EN 50379-3 [6] to:

1. measure combustion flue gas parameters of appliances in domestic premises burning 1st, 2nd or 3rd family gases of the following description:

   1. Type A, Type B and Type C gas-fired appliances, except those appliances where the appliance instructions (or design, see 7.3.2.1), prohibit combustion sampling, and,

   2. all gas-fired appliances for which the appliance manufacturer has provided a purpose-designed combustion sampling point or specific sampling instructions,

1. use as a diagnostic instrument to assist an operative:

   1. in confirming satisfactory combustion at the time of commissioning, in accordance with appliance instructions or national or local regulations or standards;

   2. in confirming satisfactory combustion at the time of servicing in accordance with national or local regulations or standards or following servicing in accordance with appliance instructions;

   3. in confirming satisfactory combustion following maintenance, in accordance with appliance instructions or national or local regulations or standards.

NOTE 1 Type A, Type B and Type C classification of gas-fired appliances are defined in 3.1.2 and more fully in CEN/TR 1749 [2].

NOTE 2 Existing national or local regulations or standards conflicting with the guidance in this Technical Specification have precedence over this guidance.

NOTE 3 It is not the intention of this Technical Specification to suggest that portable electrical combustion flue gas analysers are to be used as a substitute for normal service and maintenance carried out in accordance with the gas appliance instructions. Clause 9 describes how analysers can be used in conjunction with the appliance instructions.

NOTE 4 EN 50379–1 [4] specifies general requirements for the construction, testing and performance of portable spot reading apparatus designed to check the combustion performance of appliances in domestic premises using commercially available fuels.

NOTE 5 EN 50379–2 [5] is for apparatus intended to be used for statutory measurements. In several European countries, legal requirements exist for the performance of heating appliances (see EN 50379–1:2012 , informative Annex A [4]). Legal consequences resulting from performance measurements makes for strict requirements for the apparatus used (see EN 50379–1:2012 , normative Annexes B and C [4]).

NOTE 6 EN 50379–3 [6] is for apparatus intended to be used for non-statutory applications, which allows for reduced performance requirements for the portable electrical apparatus.

NOTE 7 This Technical Specification deals with the determination of levels of combustion gases carbon monoxide (CO), carbon dioxide (CO₂) and/or oxygen (O₂) in combustion products from gas-fired appliances. Combustion products from gas-fired appliances will contain nitrogen oxides (NO_X), predominantly nitrogen monoxide (nitric oxide, NO) and nitrogen dioxide (NO₂). This Technical Specification does not deal with the measurement of combustion products such as NO_Xand aldehydes.
