ISO/IEC 17025 Training Course – Establishment, Verification and Validation of Testing & Calibration Methods for Laboratories
Build Technically Valid Methods – Ensure Reliable Results – Meet Accreditation Requirements
The selection, development, verification, validation and implementation of testing and calibration methods are among the most critical technical requirements of ISO/IEC 17025:2017.
A laboratory's technical competence is not demonstrated solely by qualified personnel and calibrated equipment. It must also be able to demonstrate that the testing and calibration methods used are technically appropriate, scientifically valid, fit for purpose, and capable of generating reliable and traceable results.
Failure to properly establish, verify or validate laboratory methods can result in:
- Invalid test or calibration results
- Incorrect product acceptance or rejection decisions
- Customer complaints and disputes
- Accreditation nonconformities
- Regulatory compliance issues
- Increased operational risks and costs
VINTECOM International provides specialized training on the selection, development, verification and validation of testing and calibration methods in accordance with ISO/IEC 17025:2017 and international laboratory best practices.
ISO/IEC 17025 Requirements for Testing and Calibration Methods
Clause 7.2 of ISO/IEC 17025 requires laboratories to use appropriate methods and procedures for all testing, calibration and sampling activities.
Laboratories shall ensure that methods are:
- Suitable for the intended use
- Current and technically valid
- Properly documented
- Available to laboratory personnel
- Controlled through revision management
- Verified or validated before use
The laboratory shall retain objective evidence demonstrating that the selected method is capable of achieving the required performance characteristics.
Types of Methods Covered by ISO/IEC 17025
Standard Methods
Methods published by recognized standards organizations such as:
- ISO
- IEC
- ASTM
- EN
- JIS
- BS
- DIN
- AOAC
- APHA
- TCVN
These methods are generally accepted internationally and often require method verification prior to implementation.
Non-Standard Methods
Methods obtained from:
- Technical organizations
- Scientific publications
- Industry associations
- Equipment manufacturers
- Customer specifications
Such methods typically require validation before use.
Laboratory-Developed Methods
Methods designed or modified by the laboratory itself to address specific testing or calibration requirements.
These methods require comprehensive validation to demonstrate fitness for intended use.
Key Technical Topics Covered in the Training
Method Selection Criteria
Participants will learn how to select the most appropriate testing or calibration method based on:
- Customer requirements
- Regulatory requirements
- Product specifications
- Measurement capability
- Detection limits
- Laboratory resources
Method Verification
Verification demonstrates that a standard method performs as expected within the laboratory's operating environment.
Training includes:
- Verification planning
- Verification protocols
- Acceptance criteria
- Statistical analysis
- Documentation requirements
Method Validation
Validation demonstrates that a method is fit for its intended purpose.
Participants will learn how to evaluate:
Accuracy
Closeness of agreement between measured values and reference values.
Precision
- Repeatability
- Intermediate precision
- Reproducibility
Linearity
Ability to obtain results proportional to analyte concentration or measured quantity.
Detection Limit (LOD)
Lowest detectable concentration or quantity.
Quantification Limit (LOQ)
Lowest concentration or quantity that can be quantified with acceptable accuracy and precision.
Selectivity / Specificity
Ability to measure the target analyte without interference.
Measurement Range
Range over which the method provides valid results.
Robustness
Ability of the method to remain unaffected by small variations in operating conditions.
Measurement Uncertainty Evaluation
A technically valid method must support the evaluation of measurement uncertainty in accordance with ISO/IEC 17025 Clause 7.6.
The course covers:
- Identification of uncertainty sources
- Measurement models
- Type A and Type B evaluations
- Sensitivity coefficients
- Combined uncertainty
- Expanded uncertainty
- Uncertainty budgets
Participants will learn how to establish uncertainty calculations for both testing and calibration activities.
Method Performance Monitoring
The training also covers ongoing method performance monitoring through:
- Quality Control (QC)
- Control Charts
- Proficiency Testing (PT)
- Inter-Laboratory Comparison (ILC)
- Reference Materials
- Internal Quality Assurance Programs
These activities provide evidence that methods remain effective and capable of producing valid results over time.
