ISO 17025

ISO 17025:2005, the international standard for laboratory quality systems. Compliance with this standard provides a globally accepted basis for laboratory accreditation. The standard specifies the Management and technical requirements to be met by testing and calibration laboratories in both their organisation and their Management of quality. Complying with ISO 17025 will enable laboratories to identify where their current operations meet the requirements of ISO 17025 and, in those areas where they do not, it will guide them in developing systems to achieve such compliance.

ISO 17025 standard includes clauses as follows:

* Subcontracting of tests and calibrations
When a laboratory subcontracts work, whether because of unforeseen reasons (e.g. workload, need for further expertise or temporary incapacity) or on a continuing basis (e.g. through permanent subcontracting, agency or franchising arrangements), this work shall be placed with a competent subcontractor.
* Purchasing services and supplies
The laboratory shall have a policy and procedure(s) for the selection and purchasing of services and supplies it uses that affect the quality of the tests and/or calibrations. Procedures shall exist for the purchase, reception and storage of reagents and laboratory consumable materials relevant for the tests.

* Improvement
The laboratory shall continually improve the effectiveness of its Management system through the use of the quality policy, quality objectives, audit results, analysis of data, corrective and preventive actions and Management review.
* Corrective action
The laboratory shall establish a policy and a procedure and shall designate appropriate authorities for implementing corrective action when nonconforming work or departures from the policies and procedures in the Management system or technical operations have been identified.
* Preventive action
Needed improvements and potential sources of non conformities, either technical or concerning the Management system, shall be identified. When improvement opportunities are identified or if preventive action is required, action plans shall be developed, implemented and monitored.
* Control of records
The laboratory shall establish and maintain procedures for identification, collection, indexing, access, filing, storage, maintenance and disposal of quality and technical records. Quality records shall include reports from internal audits and Management reviews as well as records of corrective and preventive actions.
* Internal audits
The laboratory shall periodically, and in accordance with a predetermined schedule and procedure, conduct internal audits of its activities to verify that its operations continue to comply with the requirements of the Management system and this International Standard. The internal audit program shall address all elements of the QMS.
* Management reviews
In accordance with a predetermined schedule and procedure, the laboratory's top Management shall periodically conduct a review of the laboratory's Management system and testing and/or calibration activities to ensure their continuing suitability and effectiveness, and to introduce necessary changes or improvements.
* General technical requirements
Many factors determine the correctness and reliability of the tests and/or calibrations performed by a laboratory.
* Personnel requirements
The laboratory Management shall ensure the competence of all who operate specific equipment, perform tests and/or calibrations, evaluate results, and sign test reports and calibration certificates. When using staff who are undergoing training, appropriate supervision shall be provided.
* Accommodation and environmental conditions
Laboratory facilities for testing and/or calibration, including but not limited to energy sources, lighting and environmental conditions, shall be such as to facilitate correct performance of the tests and/or calibrations.
* General test and calibration methods and method validation
The laboratory shall use appropriate methods and procedures for all tests and/or calibrations within its scope. These include sampling, handling, transport, storage and preparation of items to be tested and/or calibrated, and, where appropriate, an estimation of the measurement uncertainty as well as statistical analysis.
* Selection of methods
The laboratory shall use test and/or calibration methods, including methods for sampling, which meet the needs of the customer and which are appropriate for the tests and/or calibrations it undertakes. Methods published in international, regional or national standards shall preferably be used.
* Laboratory-developed methods
The introduction of test and calibration methods developed by the laboratory for its own use shall be a planned activity and shall be assigned to qualified personnel equipped with adequate resources.
* Non-standard methods
