ISO 17025 standard establishes requirements for testing and calibration laboratories to demonstrate that they operate competently and generate valid results. The standard focuses on providing a systematic methodology for measuring the capability of staff in an organization to properly conduct objective tests assigned to them. It requires traceability and validation of test methods, implementation of a quality management system, and documentation of all measures taken and results obtained. Certification to this standard can increase an organization's objectivity, client satisfaction, opportunities for contracts, and ability to identify strengths, weaknesses, and areas for improvement.
