  • Emission measurements stack sampling & Accreditation

    Dr. Cor de RuiterCDR QA SUPPORT / INABJune 2011

  • Emission measurements stack sampling Quality assurance: Accreditation versus Certification Requirements for organizations involved in emission measurements stack sampling The Irish National Accreditation Board & the accreditation process (explained by Pat OBrien) Accreditation assessments in practice Most important issues addressed during accreditation assessments

  • QA Accreditation versus Certification

    EANational Accreditation Body (INAB)ISO/IEC 17011Certification BodiesISO/IEC 17021, EN 45011Inspection BodiesISO/IEC 17020Companies(may be involved inEmission measurem.ISO 9001, 14001, 18001ACCREDITATIONCERTIFICATIONEA Multilateral AgreementNOTE: ISO/IEC 17025 is NOT a certification standard !2Mutual Recognition AgreementsWith other regionsLaboratories Emission measurem. / stack samplingISO/IEC 17025

  • Accreditation versus Certification3CERTIFICATIE (for profit)ISO 9001:2008 Deming cycle (PDCA) Personnel & Organization

    Meeting customer requirements Document control Primary Processes: - more in general - no technical experts

    ACCREDITATIE (non-profit)EN-ISO/IEC 17025:2005 Deming cycle (PDCA) Personnel & Organization Independence, impartiality Meeting customer requirements Document control Primary Processes - technical performance in detail - by technical experts - aiming at justified confidence that valid test results are reported COMPETENCE !

    CERTIFICATIEAssessment of ConformityAccreditation versus Certification

  • Assessment of competence

    5Assessment by PEERS

    This is the key aspect of accreditation.Certification does not include this.

  • Requirements for organizations involved in emission measurements stack sampling

    In most European countries, organizations involved in emission measurements stack sampling, issuing test reports with regard to environmental licenses (including maximum allowable emissions), shall be accreditated against EN-ISO/IEC 17025 by its national Accreditation Body (AB). This AB shall be a signatory of the EA-MLA (ref. EA website www.european-accreditation.org)EU Directives / Regulations more and more refer to EN-ISO/IEC 17025

  • 7The General Assembly of EA has decided that, effective 1 November 2009, the national Accreditation Bodies that are signatory of the EA-MLA shall use CEN/TS 15675:2007Air Quality Measurement of stationary source emissions, in the assessment of organizations involved in emsion meaurements stack sampling CEN/TS 15675:2007 involves application of EN ISO/IEC 17025:2005 to periodic measurementsNOTE: It refers to EN 15259:2007 as mandatory standard !Requirements for organizations involved in emission measurements stack sampling

  • 27Participation in proficiency Testing A mandatory requirement for accreditation !The posibilities are limited. In particular, there are only a few locations in Europe (UK, Germany, France, Belgium) suitable for performing an on-site proficiency test for stack sampling.Accreditation assessments in practice - focus of the technical expert & lead assessorA next best could be the off-site PT tests organized by e.g. NPL (UK) of NMi-VSL (Netherlands). NMi-VSL is accredited against ILAC-G13 (ISO/IEC 17043:2010) for such PTs.

  • 28For Irish laboratories the NPL (UK) may be suitable.Accreditation assessments in practice - focus of the technical expert & lead assessorNPL (UK) organizes three proficiency testing (PT) schemes in the stack emissions measurement area: Particulate, Gas Measurement and Calibration Gas. The Particulate scheme is run annually with test items sent to participants. The Gas Measurement and Calibration Gas schemes are run bi-annually with measurements conducted at NPL.

  • 29ReportsClear and unambiguous Contents in line with CEN/TS 15675 and EN 15259- Including measurement locations and their fitness for purpose, representativity of the industrial process, test results, measurement uncertainty, reference to accreditation- Traceability to original raw data (digital and/or hardcopy)Accreditation assessments in practice - focus of the technical expert & lead assessor
