Overview of ISO 17025

The ISO 17025 standard outlines the guidelines and requirements that all testing laboratories and calibration laboratories must follow to be deemed technically competent. It covers everything from structural requirements to process requirements, setting a high standard for quality and competence.

ISO 17025:2017 - What's New?

The most recent version, ISO 17025:2017, includes updates addressing risks and opportunities and emphasizing the importance of risk-based thinking. It also introduces new normative references for laboratory customers.

The Purpose of ISO 17025 Accreditation

Accreditation to ISO 17025 provides a laboratory with international recognition of its technical competence, consistent operation, processes and capability to produce testing and calibration results that are reliable and valid.

The Importance of ISO 17025 in Testing and Calibration Laboratories

Ensuring Technical Competence

An ISO 17025-accredited laboratory is recognized as technically competent and capable of producing valid and reliable results, thereby enhancing trust among laboratory customers, regulatory authorities, inspection bodies, and accreditation bodies.

Assuring Reliable and Technically Valid Results

The ISO 17025 standard helps laboratories develop a robust quality management and quality system that guarantees reliable and technically valid results.

Key Components of ISO 17025 Accredited Quality Management System

ISO 17025 focuses on two primary sections – management requirements and technical requirements.

Management Requirements

These are related to the operation and effectiveness of the quality management system within the laboratory. They cover areas such as organizational structure, document control, review of contracts, non-conforming testing and/or calibration work, corrective action, preventive action, control of records, internal audits, and management reviews.

Technical Requirements

These pertain to the competence of staff, testing methodology, equipment, and quality assurance of test and calibration data. This section includes factors like personnel, accommodation and environmental conditions, test and calibration methods and method validation, equipment, measurement traceability, sampling, handling of test and calibration items, assuring the quality of test and calibration results, and reporting the results.

Resource Requirements

Proper resources, including competent personnel, appropriate methods of training, suitable equipment, and a suitable environment, are crucial for a laboratory to perform its technical activities and obtain accurate, reliable results.

The Role of Accreditation Bodies in ISO 17025

Accreditation bodies, often recognized by international organizations, play a vital role in the accreditation assessment process.

Laboratory Accreditation

These bodies assess the laboratory’s quality management system and technical competence. The accreditation body ensures that the laboratory can perform specific tests, procedures, measurements, or calibrations, leading to the laboratory’s accreditation.

Mutual Recognition Agreements

Many accreditation bodies are part of Mutual Recognition Agreements (MRAs), which aim to create international acceptance for accreditation systems, making the testing and calibration results globally acceptable
