Background of ISO 17025 

ISO 17025 is an internationally recognised standard for testing and calibration laboratories. This standard was first published in 1999 and has since been revised to adapt to industry practices and technological advancements. The most recent major revision occurred in 2017, emphasising a process-based approach and risk-based thinking. ISO 17025 covers various aspects of laboratory operations, including quality management systems, resource management, and process control.



Laboratories must establish documented procedures and processes to effectively control and monitor their operations. Measurement uncertainty and proficiency testing are vital requirements. Accreditation bodies assess compliance with ISO 17025. Implementing this standard improves functions, boosts customer confidence, and ensures accurate results. Labs must understand and follow ISO 17025 for a robust quality management system and continuous improvement.

Key concepts and terminology 

In ISO 17025, several important terms play a significant role in establishing laboratory competence and ensuring the quality of test results. Let's explore their definitions and their relevance: 



Accreditation: Accreditation is the formal recognition given by an accreditation body to a laboratory, indicating that it has demonstrated competence and compliance with the requirements of ISO 17025. Accreditation verifies that the laboratory meets international standards and follows best practices, enhancing its credibility and confidence in its test results. 

Traceability: Traceability refers to the ability to relate test results to internationally recognised measurement standards through an unbroken chain of calibrations. It ensures that the results obtained by the laboratory can be linked to recognised references, increasing the accuracy and reliability of measurements. 

Proficiency testing: Proficiency testing involves participating in external programs where the laboratory's performance is assessed by comparing its results to those of other participating laboratories. It helps validate the laboratory's competence, identifies areas for improvement, and ensures consistent and accurate testing. 

Measurement uncertainty: Measurement uncertainty represents the doubt or range within which the true value of a measured quantity lies. It quantifies the level of confidence in a test result, accounting for various factors that introduce variability. Estimating and controlling measurement uncertainty is crucial to ensure reliable and valid test results.

Understanding ISO 17025 requirements 

To develop a QMS based on ISO 17025, consider these key requirements: 

a) Documented policies: Establish and maintain documented policies and procedures outlining quality objectives and processes. 

b) Management responsibility: Demonstrate leadership, ensure QMS effectiveness, and foster a culture of quality. 

c) Competence and training: Ensure personnel are competent through training and competency assessments. 

d) Equipment and calibration: Establish procedures for equipment selection, verification, and calibration. 

e) Document and record control: Implement procedures for document and record management to maintain conformity. 

f) Internal audits: Conduct regular internal audits to assess QMS effectiveness and identify areas for improvement. 

g) Nonconformity management: Address nonconformities through documented procedures, corrective actions, and preventive measures.
