According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedon

PD CEN/TS 1948-5:2015CEN/TS 1948-5:2015 (E) 7 Introduction EN 1948-1, EN

39、 1948-2, EN 1948-3 and EN 1948-4 describe reference methods for the determination of PCDD/PCDF/PCB, whereas this Technical Specification gives requirements for long-term sampling measurements in connection with the appropriate analytical methods (equivalent method). In contrast to the standard refer

40、ence method (EN 1948-1) which refers to monitoring the limit value for compliance with emission limit values (ELVs) in Directives, such as Industrial Emission Directive (IED) 10, the long-term sampling is intended to determine the average concentration level during a longer period (see e.g. 12, 13).

41、 CEN/TS 1948-5 provides a method for measuring long term average mass concentrations but it does not specify its potential use by the competent authority for demonstrating compliance with long term ELVs. Long-term sampling methods are not automatic measurement methods and do not provide continuous e

42、mission monitoring data (real time display). This Technical Specification in connection with EN 1948-2 and EN 1948-3 (extraction and analysis) are necessary for the performance of long-term sampling of PCDDs/PCDFs/ PCBs. In some European Union countries PCDD/PCDF/PCB long-term sampling is an obligat

43、ory measurement for some incineration processes. In other countries of the European Union this may be obligatory in the future. The European Organization for Standardization (CEN) draws attention to the fact that it is claimed that compliance with this document may involve the use of patents concern

44、ing the use of PCDD/PCDF/PCB long-term sampling systems, described in this document. This is valid for a) the filter/condenser method (see 5.2) and b) the cooled probe method (see 5.4). CEN takes no position concerning the evidence, validity and scope of these patent rights. The holder of this paten

45、t right has ensured CEN and CENELEC that he is willing to negotiate licenses under reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this respect, the statement of the holder of this patent right is registered with CEN and CENELEC. Information may be obt

Users are encouraged to consult the databases

48、 for the most up to date information concerning patents. It should be mentioned that also a patent right existed for the dilution method (see 5.3). This patent was phased out in September 2014. In Reference 1 the results of a round robin test for long-term sampling are presented. WARNING All relevan

49、t national safety regulations shall be observed. The 2,3,7,8-chlorine substituted PCDDs/PCDFs belong to the most toxic of chemicals. In addition working at the sampling site may include exposure to a range of hazards such as poisonous/asphyxiating flue gases and working at heights. Appropriate measures shall be taken to minimize exposure to such hazards. Care shall be taken when transporting samples to avoid their breakage both to prevent contamination and to avoid sample losses.
