About ISO 17025

Overview of ISO 17025

 ISO 17025 is an international standard that specifies the general requirements for the competence of testing and calibration laboratories. It outlines the criteria that laboratories must meet to ensure they produce accurate and reliable results.

• Full name: ISO/IEC 17025:2017 – General requirements for the competence of testing and calibration laboratories
  
• Scope: Applicable to testing and calibration laboratories of all types.
  

Purpose: To evaluate the technical competence of laboratories and provide guidance for delivering reliable testing and calibration results.

Key Requirements

The requirements of ISO 17025 are divided into two main categories:

1. Management Requirements
Focus on organizational and operational processes to ensure efficient management of the laboratory:

• Quality management system: The laboratory must establish, document, and maintain a quality management system, including quality policies, objectives, and management reviews.
  
• Record management: Specifies how testing and calibration data, reports, and records should be managed, including retention periods and protection methods.
  
• Customer service: Processes must be in place to address customer requirements and expectations effectively.
  

2. Technical Requirements
Focus on the technical aspects of testing and calibration to ensure scientific accuracy and reliability:

• Personnel competence: Staff performing testing or calibration must have the appropriate education, training, skills, and experience.
  
• Equipment and environmental conditions: Equipment must be properly installed, maintained, and operated under controlled environmental conditions to avoid impacting results.
  
• Method validation: Testing and calibration methods must be appropriately selected and validated, typically through the use of standard operating procedures (SOPs).
  
• Measurement traceability: Measurement results must be traceable to internationally recognized standards.
  
• Uncertainty estimation: The uncertainty associated with testing and calibration results must be estimated and reported.
  

Reporting of results: Results must be reported accurately and clearly, with all necessary details included.

ISO 17025 Accreditation Process

 To achieve ISO 17025 accreditation, laboratories typically follow these steps:

1. Self-assessment: Evaluate the quality management system and technical competence against ISO 17025 requirements.
   
2. Application: Submit an application for accreditation to the relevant accreditation body.
   
3. Assessment: Undergo a comprehensive review, including document review and on-site assessments.
   
4. Corrective actions: Address and resolve any nonconformities identified during the assessment.
   

Accreditation: Accreditation is granted once all requirements have been met.
