ISO 17025 Accreditation: What It Means for Package Testing – Package Testing — The Definitive Resource for Packaging Test Professionals

What Is ISO 17025 Accreditation?

ISO/IEC 17025 is the international standard for the competence of testing and calibration laboratories. A laboratory that holds ISO 17025 accreditation has been independently assessed and found to meet rigorous requirements for technical competence, measurement accuracy, equipment calibration, staff qualifications, and quality management systems. When you receive a test report from an ISO 17025 accredited laboratory, you have documented assurance that the results are accurate, reproducible, and generated by a technically competent lab.

CertaPak is ISO 17025 accredited. All package testing services — drop testing, vibration testing, compression testing, and temperature and humidity testing — are performed under our accreditation scope.

Why Does ISO 17025 Accreditation Matter for Package Testing?

Test results are only as reliable as the lab that generates them. An unaccredited lab can run the same test procedure, but without independent verification of equipment calibration, measurement traceability, staff competence, and quality controls, there is no assurance that the results are accurate or reproducible. Major retailers, pharmaceutical companies, and regulatory agencies increasingly require test reports from ISO 17025 accredited laboratories as a condition of acceptance — because accreditation is the only credible proof that the lab can actually do what it claims.

Required by many major retailers, pharmaceutical companies, and regulatory agencies
Provides measurement traceability to national and international standards
Ensures equipment calibration is documented and current
Validates staff technical competence through independent assessment
Makes test reports legally and commercially defensible

What Does ISO 17025 Accreditation Require?

ISO 17025 accreditation requires a laboratory to demonstrate competence across two main areas: management requirements and technical requirements. These are assessed by an accreditation body through document review and on-site assessment.

Requirement Area	What It Covers
Management system	Document control, corrective action, internal audits, management review
Technical competence	Staff qualifications, test methods, equipment calibration, measurement uncertainty
Measurement traceability	All measurements traceable to national/international measurement standards (NIST)
Equipment calibration	Documented calibration records, calibration intervals, out-of-tolerance procedures
Test method validation	Validated test methods with documented uncertainty estimates

How Does ISO 17025 Differ From ISO 9001?

ISO 9001 is a quality management system standard — it certifies that a company has a documented quality management system in place. ISO 17025 is a technical competence standard — it certifies that a laboratory can actually generate technically valid test results. A company can hold ISO 9001 certification without being ISO 17025 accredited, and vice versa. For package testing, ISO 17025 is the relevant accreditation. ISO 9001 alone does not provide assurance of technical testing competence.

Who Accredits ISO 17025 Laboratories?

ISO 17025 accreditation is granted by national accreditation bodies that are members of the International Laboratory Accreditation Cooperation (ILAC) mutual recognition arrangement. In the United States, the primary accreditation bodies are A2LA (American Association for Laboratory Accreditation) and NVLAP (National Voluntary Laboratory Accreditation Program). Accreditations granted by ILAC member bodies are mutually recognized internationally — a test report from a US ISO 17025 accredited lab is accepted in Europe, Asia, and other regions where ILAC recognition applies.

How Do I Verify a Laboratory\’s ISO 17025 Accreditation?

Every ISO 17025 accredited laboratory holds a certificate from its accreditation body listing its accredited test methods and the scope of accreditation. You can verify accreditation status directly through the accreditation body\’s public directory. CertaPak\’s accreditation details are available on request — we provide our full accreditation scope and certificate with every test report.

Frequently Asked Questions About ISO 17025

Does ISO 17025 accreditation cover all tests a laboratory performs?

No. ISO 17025 accreditation is scope-specific. A laboratory\’s accreditation certificate lists exactly which test methods and measurement ranges are covered by the accreditation. Tests performed outside the accredited scope are not covered. CertaPak\’s accreditation scope covers our standard package testing services — confirm with us before testing if you have a specific method that must fall within our accredited scope.

Do major retailers require ISO 17025 accredited test reports?

Many do. Walmart, Amazon, Target, and major pharmaceutical distributors increasingly specify ISO 17025 accreditation as a requirement for accepting test reports. Requirements vary by company and program — confirm with your specific customer. CertaPak\’s ISO 17025 accreditation satisfies the requirements of all major retail and pharmaceutical programs we are aware of.

Is ISTA certification the same as ISO 17025 accreditation?

No. ISTA certification means a laboratory is certified by ISTA to perform ISTA protocols and issue ISTA test reports. ISO 17025 accreditation means a laboratory has been independently assessed for technical competence by a national accreditation body. They are separate and complementary — CertaPak holds both ISTA certification and ISO 17025 accreditation.

How often is ISO 17025 accreditation renewed?

ISO 17025 accreditation requires annual surveillance assessments and a full reassessment every four years (requirements vary slightly by accreditation body). Laboratories must maintain continuous compliance — any lapse in calibration, method validation, or quality system requirements can result in accreditation suspension. CertaPak maintains continuous accreditation with current calibration records on all test equipment.
