ISO 17025 Certification

What Is ISO 17025 Certification?

ISO/IEC 17025 is the international standard for testing and calibration laboratories. It specifies requirements for:

• Technical competence

• Impartiality and confidentiality

• Equipment control and calibration traceability

• Method validation and measurement uncertainty

• Risk-based thinking

• Documented management system controls

Unlike ISO 9001, ISO 17025 focuses heavily on technical validity of results, not just process control.

Certification is granted by an accreditation body after successful assessment.

Who Needs ISO 17025 Certification?

ISO 17025 is typically required or strongly preferred for:

• Calibration laboratories

• Mechanical, chemical, electrical, and materials testing labs

• Environmental and analytical laboratories

• Aerospace and defense suppliers

• Medical device and pharmaceutical testing labs

• Government contract laboratories

If your customers require traceable, defensible, accredited results — ISO 17025 certification is often mandatory.

What Does the Certification Process Involve?

1. Gap Assessment

We assess your current laboratory operations against ISO 17025 requirements, including:

• Technical procedures

• Equipment and calibration controls

• Personnel competency records

• Method validation

• Risk and impartiality safeguards

You receive a prioritized remediation roadmap.

2. System Development & Implementation

We help you implement:

• Quality Manual and laboratory procedures

• Equipment control and calibration tracking

• Measurement uncertainty documentation

• Method validation protocols

• Proficiency testing controls

• Supplier and subcontractor evaluation

• Internal audit program

• Management review structure

Our approach is practical — built around how your lab actually operates.

3. Internal Audit & Pre-Assessment

Before accreditation, we:

• Conduct a full ISO 17025 internal audit

• Simulate accreditation body interviews

• Test technical file completeness

• Validate records and traceability

• Identify remaining compliance gaps

You walk into your assessment confident and prepared.

4. Accreditation Body Assessment Support

We support you during:

• Stage 1 document review

• Stage 2 on-site technical assessment

• Nonconformity response preparation

• Corrective action root cause analysis

Our goal: zero surprises.

ISO 17025 vs ISO 9001

Many laboratories already operate under ISO 9001. While helpful, ISO 9001 alone does not demonstrate:

• Measurement uncertainty competence

• Technical method validation

• Equipment traceability to national standards

• Proficiency testing participation

• Assessor technical evaluation

ISO 17025 goes significantly deeper into laboratory competence.

If you already hold ISO 9001 certification, we can integrate 17025 efficiently into your existing system.

How Long Does ISO 17025 Certification Take?

Typical timelines:

• Small laboratory: 4–6 months

• Mid-size laboratory: 6–9 months

• Complex multi-discipline lab: 9–12 months

Timelines depend on current maturity, documentation gaps, and technical readiness.

What Does ISO 17025 Certification Cost?

Costs vary based on:

• Scope of testing/calibration

• Number of methods

• Number of technicians

• Equipment complexity

• Number of locations

Investment categories include:

• Consulting support

• Internal resource time

• Accreditation body fees

• Proficiency testing participation

We provide clear, scoped proposals — no inflated hours or unnecessary bureaucracy.
