    Technical Note for the MeasurementTraceability in the Accreditation Process 71 SD 0 005 Revision: 1.1 Date: 31.08.2011 Page: 1/2 The following certificates (hereinafter referred to as reports) are recognized as a proof of the mea-surement traceability for the accreditation of testing and calibration laboratories, medical laborato-ries, inspection bodies, producers of reference materials, and, where applicable, for the accredita-tion of providers of proficiency testing schemes and bodies operating product certification systems.1.   Reports by PTB and German designated institutes within the CIPM MRA.2.   Calibration certificates of German accredited calibration laboratories (with accreditation symbol)in the area covered by the accreditation (DAkkS calibration certificates and DKD calibration certif-icates).3.   Calibration certificates of foreign calibration laboratories (with accreditation symbol) covered bythe accreditation with the accreditation body to be a signatory to the Multilateral Agreement of EA or ILAC for calibration.4.   Reports of foreign national metrology institutes or designated institutes with a relevant entry inthe CMC lists of BIPM (Appendix C of the CIPM MRA seehttp://kcdb.bipm.org/appendixC).5.   Certificates of certified reference materials, especially if there is no other way to verify the mea-surement traceability for the respective measurand and certificates issued by accreditedproducers of reference materials (with accreditation symbol). Where there is a relevant entry forthe reference material in the CMC lists of BIPM, it should be traced to this reference material, forinstance to a certified reference material of BAM.6.   Reports without accreditation symbol (e.g. verification certificates, proprietary calibration certifi-cates) if under the terms of DIN EN ISO/IEC 17025 the issuing organization is able to producecompetence for the special calibration. The same applies for internal calibrations.Reports shall contain information on the uncertainty of measurement and measurement tracea-bility. The competence in this respect shall be documented and assessed.The recognition of these reports as a proof of traceability shall be justified and documented inthe assessment report. NoteReports without an accreditation symbol issued by accredited testing and calibration laboratories shall be treated in thesame way as calibration certificates issued by non-accredited institutions.  7.   Where the measurement traceability is not technically possible, the approach for measurementtraceability to appropriate standards stated in DIN EN ISO/IEC 17025 section 5.6.2.1.2 shall beapplied.    Technical Note for the MeasurementTraceability in the Accreditation Process 71 SD 0 005 Revision: 1.1 Date: 31.08.2011 Page: 2/2 Classification of certificates of official calibration and test certificates of German Weights andMeasures Offices   Certificates of official calibration and test certificates for special tests issued by German Weights and Measures Offices (Eichbehörden) until 31 December 2010, notwithstanding point 1 - 7 continue to berecognized as a proof of traceability if the applicable requirements of DIN EN ISO/IEC 17025:2005 are fulfilled. Statements to comply with the maximum permissible errors without indication of the uncer-tainty of measurement are considered sufficient if the maximum permissible deviation for the in-tended use of the standard or measuring instrument is sufficiently small.Certificates of official calibration and test certificates for special tests issued by German Weights and Measures Offices after 31 December 2010 are considered test reports without accreditation symbol. The applicable rule as of 1 June 2007 for calibration laboratories remains unaffected (see http://www.dkd.eu/dokumente/Merkblaetter/mb-rueckfuehrung.pdf - German version).   Classification of DAkkS and DKS calibration certificates For calibration laboratories accredited by DKD, the requirements for calibration certificates are speci- fied in the document DKD-5 (German version) and for calibration laboratories accredited by DAkkS inthe document DAkkS-DKD-5 (also German version).There are no further substantial requirements as regards the DAkkS and DKD calibration certificatesof calibration laboratories as part of quality management audits.More information can be retrieved from the internet documents ( www.dakks.de+http://www.dkd.eu    ).
