ISO/IEC 17020:2012 Accreditation
ISO/IEC 17020:2012
ISO/IEC 17020:2012 is an internationally recognized standard that sets forth requirements for the competence and consistent operation of bodies performing inspection. This standard is crucial for ensuring that inspection bodies operate impartially, reliably, and consistently across a variety of sectors. ISO/IEC 17020:2012 applies to first-party (internal inspections), second-party (inspections on behalf of a customer), and third-party (independent inspections) inspection bodies. Its implementation enhances the confidence of stakeholders, including regulators, industry partners, and consumers, in the inspection process.
History
The development of ISO/IEC 17020:2012 traces back to the broader effort to harmonize inspection procedures globally. Initially published as ISO/IEC Guide 39 in 1983, it was revised and reissued as ISO/IEC 17020 in 1998. The need for more comprehensive and updated requirements led to the publication of the current version in 2012. This latest revision aligns with other conformity assessment standards such as ISO/IEC 17021 (requirements for bodies providing audit and certification) and ISO/IEC 17025 (requirements for testing and calibration laboratories). The 2012 update ensures a more integrated approach to conformity assessment and provides clearer guidelines to enhance the effectiveness of inspection activities.

Requirements
ISO/IEC 17025: Testing Labs vs Calibration Labs.
ISO/IEC 17025:2017 is designed to cover both testing and calibration laboratories. While the core principles and requirements of the standard apply to both types of laboratories, the specific application and focus areas may differ. Understanding the distinctions between testing and calibration laboratories under ISO 17025 helps in appreciating how the standard applies to each.
Testing Laboratories
Testing laboratories perform measurements on products or materials to determine their properties, performance, and quality. They generate data that help in making decisions about the compliance of products with specified requirements.
Key Activities
- Chemical Testing: Analyzing chemical composition and properties of materials.
- Biological Testing: Examining biological samples for characteristics such as pathogens, DNA, and other biological markers.
- Mechanical Testing: Assessing mechanical properties like tensile strength, hardness, and fatigue.
- Environmental Testing: Determining how materials or products respond to environmental conditions like temperature, humidity, and UV exposure.
- Electrical Testing: Measuring electrical properties and performance of components and systems.
Requirements Specific to Testing Laboratories
- Method Validation: Ensuring that test methods are appropriate for the intended analysis and provide accurate results.
- Sampling Procedures: Defining and controlling the process of obtaining samples for testing to ensure representativeness and integrity.
- Handling of Test Items: Managing test items to avoid contamination, degradation, or mix-ups, ensuring that the test results accurately reflect the sample's properties.
Calibration Laboratories
Calibration laboratories perform measurements to determine the accuracy and performance of measuring instruments. They compare the instrument’s output with a reference standard and make adjustments to ensure that the instrument provides accurate and reliable measurements.
Key Activities
Calibration of Measuring Instruments: Adjusting instruments like thermometers, pressure gauges, scales, and other measurement tools.
- Traceability: Ensuring that all measurements are traceable to national or international standards.
- Uncertainty Measurement: Quantifying the uncertainty associated with calibration results to ensure their reliability.
Requirements Specific to Calibration Laboratories
Calibration Methods: Validating calibration methods to ensure they are appropriate and provide reliable results.
Traceability of Measurements: Ensuring that measurements are traceable to recognized standards, such as those maintained by national metrology institutes.
Management of Calibration Items: Proper handling, labeling, and documentation of items undergoing calibration to maintain integrity and traceability.
Benefits of ISO 17025 Accreditation for Both Types of Laboratories
- Demonstrates the laboratory’s competence and reliability to customers, regulatory bodies, and stakeholders.
- Accredited laboratories gain a competitive edge and are more likely to be recognized and accepted internationally.
- Encourages the implementation of efficient processes, reducing errors and improving resource utilization.
- Helps laboratories meet regulatory and contractual requirements, facilitating smoother operations.
- Incorporates risk-based thinking, helping laboratories identify and mitigate potential risks in their operations.
ISO/IEC 17025:2017 provides a comprehensive framework that addresses the unique requirements of each type of laboratory while maintaining a common focus on competence, impartiality, and consistent operation.
