Following best practices for SN EN ISO/IEC 17025:2018 compliance is essential for ensuring the competence and reliability of testing and calibration laboratories. These practices not only help in meeting the standard's requirements but also prepare laboratories for audits effectively.

Best practices at a glance

This checklist covers key best practices that align with the clauses of SN EN ISO/IEC 17025:2018. Each practice addresses critical components including competence, impartiality, management systems, and risk management, ensuring comprehensive compliance with the requirements of ISO/IEC 17025:2017.

The practices

1. Ensure Competence of Laboratory Personnel
   It is crucial to verify that all personnel possess the necessary qualifications and training to perform their tasks effectively. This practice mitigates the risk of errors in testing and calibration, which can lead to non-compliance and loss of credibility. Refer to Clause 6.2 of SN EN ISO/IEC 17025:2018 for detailed requirements on personnel competence.

2. Establish a Management System
   Implementing a robust management system is vital for maintaining consistency and quality in laboratory operations. A management system that aligns with Clause 4 of SN EN ISO/IEC 17025:2018 helps in documenting processes, which auditors expect to see during assessments. This also fosters a culture of continuous improvement.

3. Maintain Impartiality and Confidentiality
   Laboratories must ensure that their operations remain impartial and confidential to maintain trust with clients. This is essential for compliance with Clause 4.1 of the standard, focusing on avoiding conflicts of interest and protecting sensitive information, thereby preventing reputational damage.

4. Implement Risk-Based Thinking
   Adopting a risk-based approach allows laboratories to proactively identify and mitigate potential risks that could affect the quality of results. This aligns with Clause 6.1, where risk management practices enhance the reliability of testing and calibration results, ultimately fostering client confidence.

5. Control and Document Procedures
   Establishing effective document control and record-keeping processes is essential to ensure that all procedures are up to date and accessible. This practice supports compliance with Clause 8.3, as it provides a traceable history of practices that auditors can review, ensuring transparency and accountability.

6. Conduct Internal Audits Regularly
   Regular internal audits are critical for identifying areas of non-compliance and opportunities for improvement. This practice aligns with Clause 8.4, ensuring that the laboratory continuously evaluates its processes and implements corrective actions, thus enhancing overall operational efficiency.

7. Utilize Reference Materials and Ensure Traceability
   Laboratories should use certified reference materials and ensure traceability of measurements to recognized standards. This supports compliance with Clause 6.5 and enhances the reliability of test results, which is indispensable for maintaining accreditation.

8. Establish a Corrective Action Process
   Implementing a formal corrective action process is crucial for addressing non-conformities and preventing their recurrence. This practice aligns with Clause 10, where continuous improvement is emphasized, ensuring that the laboratory learns from mistakes and enhances its operational framework.
