5、imal marker. National foreword This standard has been prepared by Technical Committee CEN/TC 264 “Air quality” (Secretariat: DIN, Germany), Working Group WG 3 “Determination of HCI emissions” (Secretariat: AFNOR, France). The responsible German body involved in its preparation was the Kommission Rei

Amendments This standard differs from DIN EN 1911-1:1998-07, DIN EN 1911-2:1998-07 and DIN EN 1911-3:1998-07 as follows: a) DIN EN 1911 is now a single document replac
7、ing the previous three-part edition covering the sampling and analysis of stationary source emissions for the determination of the mass concentration of gaseous chloride expressed as HCl; b) the requirements laid down in DIN EN 15259 are now to be taken into consideration (Clause 5); c) isokinetic s
8、ampling without any side stream is now described in addition to non isokinetic sampling and isokinetic sampling with a side stream; d) the temperature of the filter housing was the subject of much discussion and varying opinions. As a result, no particular value has been specified. Instead, the filt
9、er housing temperature is to be at least 20C above the dew point (Clause 5); e) performance characteristics and a maximum allowable overall uncertainty have been specified (Clause 8); f) an example of the evaluation of overall uncertainty of measurement is given (Annex C).

29、1:2010 (E) 5 Introduction This European Standard describes the Standard Reference Method (SRM) with three alternative analytical techniques for determining gaseous chlorides content emitting to atmosphere from ducts and stacks. The specific components and the requirements for the measuring system ar
30、e described. A number of performance characteristics with associated minimum performance criteria are specified for the measuring system (see Tables 1 and 2 in 8.2). This European Standard can be used as an SRM provided the overall uncertainty of the method is less than 30,0 % relative at the daily
31、Emission Limit Value (ELV) for incineration and large combustion plants or at the ELV prescribed by the specific regulations for other plants. An Alternative Method to this SRM may be used provided that the user can demonstrate equivalence according to CEN/TS 14793. DIN EN 1911:2010-12 EN 1911:2010
32、(E) 6 1 Scope The method described in this European Standard determines the concentration of chlorinated compounds in a flue gas that after passage of the sampling system including a particle filter give Cl-ions in the absorption solution. This Standard Reference Method has been evaluated during fie
33、ld tests on waste incineration. The method applies to waste gases in which chlorides concentration expressed as HCl may vary between 1 mgm-3and 5 000 mgm-3under normal pressure and temperature conditions (see Note 1), and according to emission limit values laid down, for example, in the Council Dire
34、ctive 2000/76/EC on waste incineration plants. NOTE 1 The limit values of this European Standard are expressed in mgHCl/m3, on dry basis, at the reference conditions of 273 K and 101,3 kPa and at the reference O2concentration. NOTE 2 The required uncertainty results from the capacity of the method t
35、ested in the field (Annex D) and in the laboratory (see performance characteristics in Tables 1 and 2 and Annex C). 2 Normative references The following referenced documents are indispensable for the application of this document.
