If your laboratory’s ISO 17025 accreditation renewal is approaching, waiting until the last few weeks can turn routine compliance work into a stressful scramble. Missing records, outdated procedures, unresolved nonconformities, or incomplete internal audits can all create avoidable delays.
This practical ISO/IEC 17025 renewal checklist helps testing and calibration laboratories organize their renewal activities, identify gaps early, and keep documentation ready. It also explains how FDASINDIA can support laboratories through a structured accreditation process.
Why ISO 17025 Renewal Needs Early Preparation
ISO 17025 accreditation is not something a laboratory should treat as a one-time achievement. Maintaining competence, impartiality, consistent processes, reliable results, and appropriate documentation requires ongoing attention.
Before renewal, your laboratory should review whether its current system still reflects actual laboratory practices.
For example, suppose a testing laboratory has changed equipment, introduced new test methods, hired technical staff, or moved part of its testing operation to another area. If these changes have not been properly controlled and documented, they may become compliance concerns during assessment.
A planned renewal process gives you time to identify and address such issues rather than reacting to them at the last moment.
ISO 17025 Renewal Checklist for Your Laboratory
Use the following checklist as a practical starting point for your renewal preparation.
1. Review Your Scope of Accreditation
Start by checking your existing accreditation scope.
Confirm that:
- The listed testing or calibration activities are still being performed.
- Test and calibration methods are current.
- Equipment and facilities support the activities within the scope.
- Personnel are competent for the relevant activities.
- Any additions or changes to the scope have been properly controlled.
- Activities no longer performed are identified for appropriate action.
If your laboratory has expanded its services, do not simply assume that the existing scope covers the new work. Review the applicable requirements and determine whether a scope extension or other formal action is necessary.
2. Check Documentation and Procedures
Your quality management documentation should reflect what your laboratory actually does.
Review important documents such as:
- Quality manual or equivalent system documentation
- Standard operating procedures
- Test and calibration methods
- Equipment procedures
- Sampling procedures, where applicable
- Document-control records
- Records-control procedures
- Complaints and appeals procedures
- Risk and opportunity-related records
- Corrective-action procedures
A common problem is having a procedure that looks compliant on paper but is not followed consistently by laboratory personnel.
The objective is not to create unnecessary paperwork. Your documentation should provide clear evidence that processes are controlled and consistently implemented.
3. iso 17025 Verify Equipment and Calibration Records
Equipment plays a central role in laboratory competence.
Before renewal, review the status of equipment used for accredited activities. Check calibration, verification, maintenance, identification, and relevant performance records.
Pay particular attention to equipment that:
- Has recently been purchased
- Has undergone repair
- Has been relocated
- Has shown unusual performance
- Is approaching its calibration or verification due date
For example, if a balance used for accredited testing was serviced recently, the laboratory should be able to demonstrate that its status and suitability for use were appropriately evaluated.
4. Review Personnel Competence
Having qualified staff is important, but your laboratory should also maintain evidence of ongoing competence.
Review:
- Education and qualification records
- Training records
- Competency evaluations
- Authorization records
- Job responsibilities
- Monitoring of personnel performance
- Records for newly recruited or transferred employees
If an analyst has recently been authorized to perform a specific test, ensure that the laboratory has appropriate evidence supporting that authorization.
5. Complete Your Internal Audit
An internal audit should be treated as a preparation tool—not merely as a mandatory activity.
Your audit should help determine whether the laboratory’s management system and technical activities are working as intended.
Look beyond documentation. For example, if your procedure requires environmental conditions to be monitored, check the actual records and observe whether staff are following the procedure correctly.
Document findings clearly and ensure identified issues are addressed.
6. Review Management Review Records
Management review provides an opportunity for laboratory leadership to evaluate the continuing suitability and effectiveness of the management system.
Review whether your management review has considered relevant inputs such as:
- Internal and external audit results
- Customer feedback
- Complaints
- Corrective actions
- Changes affecting the laboratory
- Achievement of objectives
- Resource requirements
- Risks and opportunities
- Improvement activities
The key is to demonstrate that management is actively evaluating laboratory performance and taking appropriate decisions.
7. Close Previous Nonconformities
Previous assessment findings should receive special attention.
Create a simple tracker showing:
| Item | What to Check |
| Finding | What was identified? |
| Root cause | Why did it occur? |
| Correction | What was done immediately? |
| Corrective action | What was changed to prevent recurrence? |
| Evidence | What records demonstrate completion? |
| Effectiveness | Has the action actually worked? |
Simply correcting a document may not be enough if the underlying cause has not been addressed.
For instance, repeatedly missing equipment checks may indicate a weakness in responsibility assignment or monitoring rather than a one-time documentation error.
8. Verify Measurement and Quality Assurance Activities
Testing and calibration laboratories should review the technical controls relevant to their accredited activities.
Depending on the laboratory’s scope, this may include:
- Quality control activities
- Proficiency testing
- Interlaboratory comparisons
- Measurement traceability
- Method validation or verification
- Uncertainty evaluation, where applicable
- Reference materials
- Monitoring of test or calibration results
The exact evidence required will depend on the laboratory’s activities and applicable requirements.
ISO/IEC 17025 Certification vs Accreditation
Laboratories sometimes use the terms ISO/IEC 17025 certification” and “accreditation” interchangeably, but they are not necessarily the same thing.
ISO/IEC 17025 establishes requirements for the competence of testing and calibration laboratories. Accreditation involves an accreditation body assessing the laboratory against applicable requirements and its defined scope.
Therefore, laboratories preparing for renewal should focus not only on having an ISO 17025 standard document or certificate, but on demonstrating technical competence and effective implementation of the management system.
What About Medical Laboratories?
This distinction is particularly important for hospital and medical laboratory teams.
ISO 15189 accreditation is specifically designed for medical laboratories, whereas ISO/IEC 17025 is generally associated with testing and calibration laboratories. A hospital may operate different laboratory functions, and the applicable accreditation framework should be determined according to the nature and scope of those activities.
Therefore, medical laboratory accreditation should not automatically be treated as the same process as testing laboratory accreditation.
If your organization operates multiple laboratory functions, clearly defining the applicable requirements can make the laboratory accreditation process much easier to manage.

A Simple Timeline for ISO 17025 Renewal Preparation
Instead of treating renewal as a single deadline, divide the work into stages.
Early preparation
Review the accreditation scope, previous findings, procedures, equipment records, personnel competence, and major changes.
System review
Conduct internal audits, management review, document review, and technical checks.
Corrective-action stage
Address nonconformities and verify that corrective actions are effective.
Final readiness check
Confirm that records are complete, personnel are prepared, equipment status is current, and the laboratory can demonstrate implementation of its procedures.
This approach reduces last-minute pressure and gives laboratory management a clearer picture of readiness.
