September 2019 2 of 11 1 Scope The purpose of this document is to provide additional information on the presentation of calibration results. It takes into account all requirements agreed in the European co-operation for Accreditation (EA), including those from DIN EN ISO/IEC 17025:2018, for the form and content of calibration certificates in analogue form or calibration certificates in digital form. Both forms must meet the requirements of DIN EN ISO/IEC 17025:2018. The document refers exclusively to analogue or digital calibration certificates issued within the framework of an accreditation granted by DAkkS. In the following, only analogue calibration certificates are considered1. The sample calibration certificate shown in Annex 1 is provided for the purpose of achieving a uniform appearance of all calibration certificates. It takes all requirements set out above into account. The layout is not obligatory. It can be assumed that conformity assessment bodies using this layout comply with the requirements for calibration certificates. 2 Terms Digital calibration certificate Digital data record whose integrity and authenticity can be verified by cryptographic methods (DCC = digital calibration certificate). Calibration certificate Non-digital records that can be sent for example in paper form. 1 For digital calibration certificates, detailed documentation with good-practice examples is being prepared by PTB in consultation with DAkkS. The first version of this documentation will be published at the end of 2019. Presentation of calibration results and the use of the DAkkS calibration mark 71 SD 0 025 | Revision: 1.1 | 19. September 2019 3 of 11 3 Presentation of calibration results in accordance with DIN EN ISO/IEC 17025:2018 3.1 Calibration certificates The calibration certificates issued by accredited calibration laboratories must comply with the requirements of DIN EN ISO/IEC 17025:2018 (Sections 7.8.1, 7.8.2, 7.8.4 and, if applicable, 7.8.6) and of ILAC-P14. For the determination of measurement uncertainties, the rules of EA-4/02 M apply. For the indication of measurement results, internationally standardised presentation in accordance with DIN EN ISO 80000-1 applies. For conformity declarations, regulations of ILAC-G8 and JCGM 106 must also be noted. The use of the accreditation symbol provides documented evidence that the metrological traceability of the calibration item has been demonstrated. This makes it easier for the user to verify compliance with the requirements of DIN EN ISO/IEC 17025:2018. For the drawing up of calibration certificates, it is possible to choose from the following two options: • Analogue calibration certificate (recommended sample as per Annex 1 or Annex 2). • If the binding requirements are met as mentioned above, other options are also permitted. The measurement results of the calibrations must be within the scope of accreditation of the calibration laboratory. 3.2 Recommended sample of a calibration certificate The samples of calibration certificates shown in Annex 1 and 2 are recommendations. Since the implementation of accreditation and the associated requirements for calibration certificates in Germany and Europe, they have proven themselves to be successful in a similar form and have a high recognition value. Page 1 should be laid out uniformly in accordance with the given sample (Annex 1 or 2, German-English). Other language combinations with German or English are possible. The calibration mark should be designed in accordance with the sample given in Annex 3. For reliable traceability and identification, the use of the calibration mark on subsequent pages of the calibration certificate is also recommended. For the use of the accreditation symbol or the combined ILAC-MRA symbol, the binding rules of 71 SD 0 011 apply. Presentation of calibration results and the use of the DAkkS calibration mark 71 SD 0 025 | Revision: 1.1 | 19. September 2019 4 of 11 For the use of additional symbol (e.g. DKD logo), the calibration laboratory issuing the calibration certificate is solely responsible (note: legal agreements may need to be concluded with the licensor of the symbol). A reference to certifications (e.g. to ISO 9001) is not permitted in the calibration certificate (see EA-3/01 M). Templates for calibration certificates can be found in Annex 1 (sample calibration certificate with ILAC-MRA symbol) and Annex 2 (sample calibration certificate without ILAC-MRA symbol) to this document. 4 Informative documents (EA, IAF, ILAC, DAkkS) DIN EN ISO/IEC 17025:2018 General requirements for the competence of testing and calibration laboratories EA-3/01 M:2012 EA Conditions for the use of accreditation symbols, text reference to accreditation and reference to EA MLA Signatory status EA-4/02 M:2013 Evaluation of the Uncertainty of Measurement in Calibration ILAC-P14:01/2013 ILAC Policy for Uncertainty in Calibration ILAC-G8:2009 Guidelines on Reporting of Compliance with Specification JCGM 106:2012 Evaluation of measurement date – The role of measurement uncertainty in conformity assessment 71 SD 0 011_e Rules for accredited conformity assessment bodies on the use of the accreditation certificate, the accreditation symbol of the Deutsche Akkreditierungsstelle GmbH as well as other references to the accreditation DIN EN ISO 80000-1:2013-08 Quantities and units – Part 1 Presentation of calibration results and the use of the DAkkS calibration mark 71 SD 0 025 | Revision: 1.1 | 19.

September 2019 9 of 11 Annex 3 DAkkS calibration mark DAkkS recommends the use of the present DAkkS calibration mark. These have proven themselves for decades and have a high recognition value. If they are used, the following rules are binding. 1. DAkkS calibration mark a) DAkkS calibration mark with layout The DAkkS calibration mark facilitates the identification of the measurement object associated with the result report. The layout is to be used as specified below. 18 mm 1) 000000 2) D-KYYYYY-ZZ-NN 3) 1) 25 mm yyyy-mm Field for entering the sequential calibration number; sequence number of calibration certificates issued 2) DAkkS case number in accordance with the regulation on the accreditation symbols 3) Field for entering year and month of calibration Presentation of calibration results and the use of the DAkkS calibration mark 71 SD 0 025 | Revision: 1.1 | 19. September 2019 10 of 11 b) DAkkS calibration mark with layout The DAkkS calibration mark facilitates the identification of the measurement object associated with the result report. The layout of the DAkkS calibration mark corresponds to that of the DAkkS calibration mark: 18 mm 1) 000000 2) D-KYYYYY-ZZ-NN 3) 1) 25 mm yyyy-mm Field for entering the sequential calibration number; sequence number of calibration certificates issued 2) DAkkS case number in accordance with the regulation on the accreditation symbols 3) Field for entering year and month of calibration 2. Size The dimensions specified under item 1 must always be adhered to. Reductions are permitted if the calibration item does not allow such a calibration mark to be affixed, provided that the mark is still clearly legible. 3. Colour DAkkS calibration marks should be in blue [HKS 47K, corresponds to CMYK 100/0/0/0], the lettering in black. Other colours are permitted, but must not impair legibility and require approval. 4. Quality The DAkkS calibration mark must be made of suitable material and labelled to ensure that the following are excluded where possible • The affixed mark is unintentionally detached from the calibration item • The lettering runs, becomes blurred or becomes illegible due to abrasion or brightening • The functionality of the calibration item is restricted Presentation of calibration results and the use of the DAkkS calibration mark 71 SD 0 025 | Revision: 1.1 | 19.
