Objectives of Laboratory Accreditation Systems

Lab accreditation systems are designed to include these specific objectives:
1. Ensure validity of test data by ensuring that the laboratory is operating to the best of its ability.
2. Promote the acceptance of test data by users of laboratory services so that data produced by one lab can be accepted by another without further tests.
3. Facilitate international trade through the acceptance of test data from accredited laboratories.
4. Make more efficient use of testing facilities within a country by coordinating existing capabilities.
5. Add to the credibility and give additional status to competent laboratories.
6. Promote good testing practices.
7. Improve testing methods by providing feedback to standards-producing bodies on the adequacy of test methods.
8. Provide technical and other information to accredited laboratories
9. Facilitate establishment of mutual recognition agreements.
