This European Standard specifies the requirements for an instrument using flame ionisation detection, together with procedures for its operation. The results obtained using this standard are expressed in milligrams per cubic metre (mg/m³) as total carbon (TVOC). This European Standard is not applicable for permanently installed automated measuring systems (AMS). Alternative methods to this method may be used provided that the user can demonstrate equivalence, based on the principles of CEN/TS 14793. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

Figure 2 — Example of the set-up of the measuring system 5 Requirements for apparatus and gases 5.1 Requirements for the measurement system The sampling system shall meet the following requirements:
 It shall be made of stainless steel, polytetrafluoroethylene or polypropylenefluoride. If an alternative material is used, it shall be proven that it is chemically and physically inert to the constituents of the flue gas under analysis.  The design and configuration of the sampling device used shall ensure the residence time of the sample gas within the device is minimised in order to reduce the response time of the measuring system. It will be designed to ensure a sample residence time less than 60 s. With long sampling lines or high flow resistance, the use of an external pump with bypass is recommended.  It shall be heated throughout to at least 180 °C. NOTE Sampling lines in PTFE have a maximum temperature of 200 °C. All instruments that are certified are tested at 180 °C.  It shall have a heated filtering device upstream of the sampling line to trap all particles liable to impair the operation of the apparatus.  It shall have an inlet for applying zero and span gases at or close to the probe inlet of the sampling probe, upstream of the filter. This is to check the sampling system including the filter assembly. The FID and sampling system shall comply with the performance requirements of EN 15267-3. SIST EN 12619:2013

A.8 and Annex B Sampling system check once for each measurement series
6.2.2 Leakage check once for each measurement series
6.2.2 Zero drift at the beginning and end of the measuring period and at least once a day < 5 % 6.2.3 Span drift at the beginning and end of the measuring period and at least once a day < 5 % 6.2.3 Regular maintenance of the analyser as required by the manufacturer
Cleaning or changing of sampling line and particulate filters c once for each measurement series, if needed
a A repair that might affect the performance of the instrument. b Only those interferences shall be checked which have proven to be relevant during instrument performance testing. c The particulate filter shall be changed periodically depending on the dust load at the sampling site. During this filter change, the filter housing shall be cleaned. 5.2 Operational gases 5.2.1 General A number of operational gases are required when using this standard. The use of combustion air or fuel gas whose concentration in TVOC is lower than 0,2 mg/m³ (as carbon) or of purity 99,998 % shall be used. This avoids any risk of influence of this gas on the result of the measurement. 5.2.2 Fuel gases The fuel gas shall be specified by the equipment manufacturer and according to the certification to EN 15267-1, EN 15267-2 and EN 15267-3. Commonly used gases include:  hydrogen;  hydrogen/helium mixture;
When the analyser is used for regulatory purposes, the span gas shall have a known concentration of approximately the half-hourly ELV or 50 % to 90 % of the selected range of the analyser. The span gas will be propane with the same oxygen concentration in the complementary gas in the zero and in the span gas to take into account the same level of influence at the zero point and the span point during the adjustment of the analyser. 6 Measurement procedure 6.1 General The planning and sampling strategy shall follow the requirements of EN 15259. The following text describes the routine operation procedures required by the standard; a more detailed procedure for determining the instrument performance characteristics is given in Annex A. 6.2 Adjustments and checks 6.2.1 Instrument adjustment The FID shall be set up according to the manufacturer's instructions in order to ensure that the instrument is correctly adjusted as specified in Table 1. At the beginning of the measuring period, zero and span gases are supplied to the analyser directly, without passing through the sampling system. Adjustments are made until the correct zero and span gas values are given by the data sampling system:
 adjust the zero value;  adjust the span;  finally, re-check zero to see if there are no significant changes (zero deviation lower than two times the repeatability at zero). Repeat the adjustment procedure until this is achieved. SIST EN 12619:2013
