6 Needs for Qualification National Accreditation Process: generally represented by: Accreditation steps PT Information Documents for accreditation Tariffs Financial information European /International recognition agreements facilitate the access & benchmarking among laboratories at the European level of EA-MLA (Multilateral Agreement) through which the signatory parties recognize each other's granted accreditations and the reports/certificates issued by the entities accredited by it, with periodic mutual evaluation. at international level of IAF-MLA, respectively ILAC-MRA (Multilateral Recognition Arrangement). offers confidence in the accreditation bodies and in their ability to determine the competence of the certification bodies, being WW recognized. ILAC - the International Laboratory Accreditation Cooperation - is an international cooperation of laboratory and inspection accreditation bodies.

7 EA-2/09 EA Policy on the Accreditation of Providers of Proficiency Testing Schemes Proficiency testing schemes - used by laboratory accreditation bodies as part of the accreditation and surveillance processes to assess the ability of laboratories to competently perform tasks. Proficiency tests complement the traditional technique of on-site laboratory assessment by technical experts. Proficiency testing is considered to cover both calibration and testing activities. The existence of accredited PT providers should not prevent accreditation bodies from developing and operating their own proficiency testing to: assess laboratories' performance before accreditation is granted survey the performance of accredited laboratories organize EA inter-laboratory comparisons as a means to establish confidence among EA members.

8 On Proficiency Testing application to QA of EE Labs PT ( defined by ISO/IEC Guide 43: 1997, Part 1 [1]) - Powerful tool to help a laboratory to demonstrate such competence to an accreditation body or other third party. Primary aim of proficiency testing to provide a QA tool for individual laboratories to enable them to compare their performance with similar laboratories, to take any necessary remedial action and /or facilitate improvement. A priori a demonstration of competence has to be given by a laboratory during an accreditation assessment in accordance with ISO/IEC 17025:1999* and ISO/IEC Guide 58 (1993). PT enables laboratories to monitor their tests over time. Improvement and maintenance of the quality in the laboratory can be also achieved by regular participation in interlaboratory comparisons used for other purposes but modified for the purposes of proficiency testing Up to now there has been no common policy for the effective use of this kind of interlaboratory comparison in the accreditation context.

9 Good practice for EE Labs in cost-effective use of PT in accreditation. QA tool for individual laboratories to enable them to compare their performance with similar laboratories, to take any necessary remedial action, and to facilitate improvement; Accreditation assessment in accordance with ISO/IEC 17025:1999 and ISO/IEC Guide 58 (1993 Other documents ISO/IEC Guide 43:1997, Part 1 [1] ILAC G13:2000 [5].

10 Aspects on PT Laboratory Proficiency Testing; Determination of laboratory testing performance by means of inter-laboratory comparisons 1. Qualitative schemes - for example where laboratories are required to identify a component of a test item. 2. Data transformation exercises 3. Single item testing - where one item is sent to a number of laboratories sequentially and returned to the organiser at intervals. 4. One-off exercises - where laboratories are provided with a test item on a single occasion. 5. Continuous schemes - where laboratories are provided with test items at regular intervals on a continuing basis. 6. Sampling - for example where individuals or organisations are required to take\samples for subsequent analysis. ISO/IEC Guide 43:1997 [1] 3.6 Interlaboratory comparisons Organisation, performance and evaluation of test on the same or similar test items by two or more laboratories in accordance with pre-determined conditions. a) the validation of methods c) the self-assessment of a laboratory s performance in a test Bilateral proficiency testing Blind test item

11 PROFICIENCY TESTING IN ACCREDITATION The performance of accredited laboratories in proficiency testing is one of many tools that should be used in accreditation procedures by accreditation bodies. Possible types of proficiency testing in accreditation are given in 4.1 and include: a) Bilateral proficiency testing; b) Proficiency testing schemes; c) Inter-laboratory comparisons designed primarily for other purposes: Remarks of advantages: Significant added value to accredited laboratories, or those seeking accreditation, from participation in appropriate proficiency testing schemes. Appropriate and cost-effective use of PT scheme results by accreditation bodies may reduce the cost to laboratories of accreditation. Participating in Proficiency Testing schemes can be a part of a contract between the laboratory and the customer, e.g. an authority, and in this case mandatory for the laboratory. The accreditation body should not interfere with any contracts between laboratories and their customers.

12 ACTIONS (cf.iso/iec and ISO/IEC Guide 58 Arrangement) Actions for accreditation bodies and assessors (in order to create the necessary transparency and confidence in the technical competence of the accreditation bodies and the accredited laboratories in the environment of the ILAC Mutual Recognition) Collection & provision of general information about appropriate PT schemes (e.g. from EPTIS) [4] laboratory responsibility. Benefits promotion of participation in proficiency testing; How performance is used to help assess laboratories competence. Supporting of organisation or arrangement of proficiency tests, wherever possible and useful in the most cost-effective manner. The accreditation body should judge the appropriateness of proficiency tests in which the laboratory participates, which will be taken into account in the accreditation. Where the accreditation body recommends participation in any particular PT scheme, for its accredited laboratories, it should satisfy itself of the competence of the organisation providing the proficiency test. Establishment of criteria for the acceptance of proficiency testing results, where necessary. Check of written procedure in the Quality Manual (QM) or in laboratory instructions covering participation in proficiency testing, including how the performance in proficiency testing is used to demonstrate the laboratory's competence The use of results in all types of proficiency testing by accreditation bodies should be performed in accordance to the flow chart in Annex 2 of this document and ISO/IEC Guide 43:1997. Part 2, Section 6 [2].

13 Possible Actions for EE Labs Appropriate participation in Proficiency Testing benefit - both in bilateral PT and inter-laboratory comparisons, covering the accreditation scope, combined in an useful cost-effective manner. Need of laboratory to satisfy itself of the competence of the providers of PT schemes, based on voluntary participation. The laboratory policy for participation in proficiency tests as a form of external quality control should be adequately described in the Quality Manual Planning, performance/operation, evaluation, corrective action, records and its storage. The preparedness of laboratory to justify non-participation in readily available proficiency testing schemes, where one or more appropriate schemes exist.

15 Some final remarks Start of Accreditation procedure along with the Vision of future possible PT- It should be suitable? If yes - Collecting& promoting benefits for future bilateral or EU Consortium (see SERIES) for future projects in FP8 Argument: Increased transparency of results world wide, respectively WW recognition of competence in Experimental EE of European Laboratories!
