ISO 17025 Accredited Calibration Laboratories
Accredited calibration helps customers document accuracy, support quality requirements, and choose the right path for equipment that matters.

Calibration Confidence Starts with Competence
ISO/IEC 17025 accreditation helps identify laboratories that have demonstrated technical competence within a defined scope and operate under a laboratory quality management system.
Michelli's accredited metrology labs have been examined and audited by an accrediting body. That review evaluates whether the laboratory's calibration processes, measurement capabilities, and quality management system support consistently dependable results.
For customers, that means accredited calibration can provide an added level of confidence when equipment accuracy, traceability, audit readiness, or documentation matter.

Matters
Accredited calibration depends on equipment, location, capability, and scope
What ISO/IEC 17025 Accreditation Means
Accreditation is different from a general claim of compliance. It requires review by an accrediting body and applies to specific capabilities listed within a defined scope.
Technical Competence
The laboratory must demonstrate the technical ability to perform calibration activities within its accredited scope.
Quality Management
Accredited laboratories operate under a laboratory quality management system designed to support consistent processes and reliable documentation.
Defined Scope
The scope of accreditation lists the specific measurement capabilities covered. Customers should review the applicable scope for specific devices.
Standard Traceable Calibration or ISO/IEC 17025 Accredited Calibration?
Not every device or application requires ISO/IEC 17025 accredited calibration. Some customers need standard traceable calibration, while others require accredited calibration because of internal quality systems, customer requirements, audits, or regulated applications.
Michelli can help customers review the device, application, documentation needs, and applicable scope to determine the right calibration path.
Be Careful with "ISO 17025 Compliant" Claims
Accreditation and compliance are not the same. Accreditation means an accrediting body has evaluated the laboratory against the ISO/IEC 17025 standard and the laboratory's defined scope. Customers should review accreditation documentation when accredited calibration is required.
Use standard traceable calibration when appropriate
Standard traceable calibration is a practical option for many routine equipment and quality needs when accredited calibration is not required.
Use ISO/IEC 17025 accredited calibration when required
Accredited calibration is often requested for audits, regulated environments, customer requirements, or quality systems that specify accredited calibration.
Review the applicable scope
Accreditation is not universal across every device or service. The scope identifies what is covered.
Ask Michelli for help choosing the right path
Michelli can help determine what documentation and calibration level fits your application.
Understanding Accreditation Scope
ISO/IEC 17025 accreditation does not automatically apply to every device, service, or location. Each accredited laboratory has a defined scope that identifies the measurement capabilities covered by that accreditation.
Before scheduling accredited calibration, Michelli can help review your equipment, measurement discipline, location needs, and documentation requirements so the correct service path is selected.
Why scope review matters
Accredited calibration should match the device, range, measurement discipline, location, and documentation your quality program requires. Reviewing the scope up front helps avoid confusion and supports better audit readiness.
