TL;DR
- ISO/IEC 17025 accreditation formally recognizes a laboratory’s competence to perform specific testing or calibration activities within an approved scope.
- Laboratories must demonstrate technical competence, impartiality, reliable methods, suitable equipment, traceability, and effective quality-management processes.
- The accreditation process typically involves defining the scope, assessing gaps, implementing controls, submitting an application, completing an assessment, and resolving findings.
- Digital laboratory systems can support documentation, sample traceability, and quality workflows, but accreditation depends on demonstrated competence and assessment by an accreditation body.
ISO 17025 accreditation helps testing and calibration laboratories demonstrate that their results are produced competently, impartially, and consistently. It provides customers, regulators, and other stakeholders with independent evidence that a laboratory can perform the activities included in its approved scope.
For laboratories preparing for accreditation, the challenge extends beyond writing procedures. Teams need to establish reliable testing methods, maintain equipment and personnel records, control documents, demonstrate measurement traceability, and show that their quality-management system works in practice.
This guide explains ISO 17025 accreditation requirements, the application process, the documentation laboratories should prepare, and how to maintain readiness after accreditation.
What Is ISO 17025 Accreditation?
ISO 17025 accreditation is the formal recognition that a testing or calibration laboratory has demonstrated competence against the applicable requirements of ISO/IEC 17025:2017 for defined laboratory activities.
The standard, General requirements for the competence of testing and calibration laboratories, addresses competence, impartiality, and consistent laboratory operations. ISO reviewed and confirmed the 2017 edition in 2023, so it remains the current edition listed by ISO.
Accreditation is granted by an appropriate accreditation body following an assessment. It applies to the activities listed in the laboratory’s approved scope, not automatically to every service the organization provides.
ISO 17025 accreditation vs. certification
Although laboratories often search for “ISO 17025 certification,” the technically appropriate term is generally ISO/IEC 17025 accreditation.
Certification usually confirms that a management system, product, service, or person meets specified requirements. Laboratory accreditation evaluates technical competence to perform defined testing or calibration activities.
If your objective is to demonstrate laboratory competence against ISO/IEC 17025, identify an appropriate accreditation body and confirm its application criteria.
Who needs ISO 17025 accreditation?
Accreditation may be relevant to laboratories performing activities such as:
- Chemical, biological, or microbiological testing.
- Mechanical, electrical, or materials testing.
- Environmental testing and analytical measurements.
- Instrument calibration and dimensional measurement.
- Contract testing and other laboratory services where customers or regulations require demonstrated competence.
Whether accreditation is mandatory depends on the applicable regulations, contracts, industry requirements, and customer expectations.
For laboratories working toward accreditation, the ISO 17025 compliance guide provides additional context on the requirements and supporting laboratory processes.
ISO 17025 Accreditation Requirements
ISO/IEC 17025 covers both the laboratory’s management system and its technical operations. Laboratories should assess the requirements relevant to their activities and the scope they intend to seek accreditation for.
1. Impartiality, confidentiality, and personnel competence
Laboratories must identify and address risks to impartiality and protect confidential information. Responsibilities and access to sensitive records should be appropriately controlled.
Personnel performing laboratory activities must be competent for their assigned responsibilities. Supporting evidence may include qualifications, training, authorization records, and competency assessments.
2. Equipment, methods, and measurement traceability
Laboratories need suitable equipment, appropriate environmental conditions, and controlled testing or calibration methods.
Relevant activities include equipment calibration and maintenance, method verification or validation, and establishing metrological traceability where required.
For method-specific preparation, see the guide to ISO 17025 method validation. It explains when validation is needed and how laboratories can document evidence that a method is fit for its intended use.
3. Technical records and measurement uncertainty
Laboratories must maintain appropriate technical records that allow activities and results to be understood and traced. Measurement uncertainty must be evaluated where required by the applicable standard and method context.
Records should be sufficiently complete to support review, explain relevant calculations, and demonstrate how results were obtained.
4. Document control, audits, and corrective action
A laboratory needs controlled procedures and records, a process for addressing nonconforming work, and appropriate corrective-action and internal-audit activities.
Staff should be able to access current approved procedures, while historical records remain available when needed. Findings should be investigated, documented, and followed through to an appropriate conclusion.
The ISO 17025 internal audit checklist can help structure an internal review before an external assessment.
How to Get ISO 17025 Accreditation: Step by Step
The exact process, timelines, and documentation depend on the accreditation body and the laboratory’s requested scope. The following steps provide a practical preparation framework.
Step 1: Define the accreditation scope
Identify the tests, calibrations, methods, measurement ranges, sample types, and locations you want included in the accreditation scope.
A clearly defined scope helps the laboratory identify the necessary resources, technical evidence, and assessment requirements.
Step 2: Conduct a gap assessment
Compare existing laboratory practices with the applicable ISO/IEC 17025 requirements and the accreditation body’s additional criteria.
Review personnel competence, equipment, methods, records, traceability, document control, internal audits, and corrective-action processes. Record gaps and assign owners and target dates.
Step 3: Implement and document the required controls
Address identified gaps through appropriate procedures, training, technical controls, and quality-management processes.
For example, a laboratory may need to improve equipment records, formalize method verification, strengthen document approval, or establish a more consistent approach to investigating nonconforming work.
Step 4: Build objective evidence and review readiness
Collect evidence showing that procedures are implemented in practice, not merely written down. This can include technical records, calibration certificates, training records, method studies, quality-control results, internal-audit findings, and corrective-action records.
Conduct an internal review to identify unresolved issues before submitting the application.
Step 5: Apply to an appropriate accreditation body
Select an accreditation body that covers your laboratory’s activities and relevant technical scope. Confirm its application process, current criteria, fees, and documentation requirements.
For laboratories in India, NABL’s testing laboratory accreditation information and calibration laboratory accreditation information are useful starting points.
Step 6: Complete the assessment and address findings
The accreditation body reviews the application and assesses the laboratory against the applicable requirements. Assessment activities may include document review, interviews, examination of equipment and records, and observation of laboratory activities.
If nonconformities are identified, the laboratory must provide appropriate corrections, investigate causes where required, implement corrective actions, and submit supporting evidence according to the accreditation body’s process.
Step 7: Maintain accreditation
Accreditation is not a one-time documentation exercise. Laboratories must continue to demonstrate competence, maintain their management system, monitor result validity, and meet applicable surveillance and reassessment requirements.
Changes to methods, equipment, personnel, facilities, or scope should be evaluated through appropriate controls.
How Scispot Supports ISO 17025 Accreditation Readiness
ISO 17025 accreditation depends on demonstrated laboratory competence. Software can support the processes and evidence behind that competence, but it cannot independently grant accreditation or guarantee compliance.
Scispot helps laboratories organize data, laboratory workflows, and related records in a connected digital environment.
Depending on the laboratory’s configured solution and requirements, relevant areas to evaluate include:
- Sample and test traceability: Connect sample information, testing workflows, results, and associated records.
- Workflow consistency: Structure laboratory processes to reduce reliance on disconnected spreadsheets and manual handoffs.
- Documentation and record access: Organize relevant operational records to support review and retrieval.
- Quality process support: Evaluate how documentation, approvals, and quality-related workflows can be configured for the laboratory’s needs.
- Connected laboratory systems: Assess how existing instruments and applications can be integrated into the laboratory’s data environment.
Laboratories should confirm the exact capabilities and configuration required during a product evaluation. They remain responsible for ensuring the system is suitable for its intended use and that all applicable requirements are met.
