The general conditions pertaining to assignments accepted by Danish Technological Institute shall apply in full to the technical testing and calibration at Danish Technological Institute and to the completion of test reports and calibration certificates within the relevant field.

Danish Accreditation (DANAK) DANAK was established in 1991 in pursuance of the Danish Act No. 394 of 13 June 1990 on the promotion of Trade and Industry. The requirements to be met by accre-dited laboratories are laid down in the “Danish Agency for Trade and Indu-stry‟s ("Erhvervsfremme Styrelsens") Statutory Order on accreditation of laboratories to perform testing etc. and GLP inspection. The statutory order refers to other documents, where the criteria for accreditation are specified further. The standards DS/EN ISO/IEC 17025 “General requirements for the compe-tence of testing and calibration laborato-ries” and DS/EN 45002 “General criteria for the assessment of testing laboratories” describe fundamental criteria for accreditation. DANAK uses guidance documents to clarify the requirements in the standards, where this is considered to be necessary. These will mainly be drawn up by the “European co-operation of Accreditation (EA)” or the “International Laboratory Accreditation Co-operation (ILAC)” with the purpose of obtaining uniform criteria for accreditation. In addition, DANAK draws up Technical Regulations with specific requirements for accreditation that are not contained in the standards. In order for a laboratory to be accredited it is, among other things, required: - that the laboratory and its personnel are not subject to any commercial, financial or other pressures, which might influence their technical judgement

- that the laboratory operates a documented quality system - that the laboratory has at its disposal all items of equipment, facilities and premises required for correct per formance of the service that it is accredited to perform - that the laboratory management and personnel have technical compe- tence and practical experience in performing the service that they are accredited to perform - that the laboratory has procedures for traceability and uncertainty calcula- tions - that accredited testing or calibration is performed in accordance with fully validated and documented methods - that the laboratory keeps records, which contain sufficient information to permit repetition of the accredited test or calibration - that the laboratory is subject to sur- veillance by DANAK on a regular basis - that the laboratory shall take out an insurance, which covers liability in connection with the performance of accredited services Reports carrying DANAK„s logo are used, when reporting accredited ser-vices and show that these have been performed in accordance with the rules for accreditation.
