ISO/IEC 17025 Accreditation

AASHTO re:source has been performing assessments for ISO/IEC 17025 since March 2000. The title of this ISO standard is “General Requirements for the Competence of Testing and Calibration Laboratories". ISO is the International Organization for Standardization and this internationally-recognized standard is specifically geared towards testing and calibration laboratories, as its title states.

Accreditation for ISO/IEC 17025 is available to all laboratories that are currently accredited by the AASHTO Accreditation Program (AAP) for AASHTO R 18, in any testing field(s). Many requirements of ISO/IEC 17025 are similar to AASHTO R 18, but there are also additional requirements such as contract review, purchasing, customer feedback, and uncertainty of measurement. You may purchase a copy of the standard at www.ansi.org or www.iso.org to review the requirements.

If your organization desires worldwide recognition of your products or services, or if you simply want to go the extra step in the pursuit of quality, recognition for ISO/IEC 17025 may be of interest to you.

The On-Site Assessment

The ISO/IEC 17025 assessment is usually a separate assessment from your regular AASHTO re:source and/or CCRL on-site assessment(s), which involve demonstrations of test methods and a thorough review of the requirements in AASHTO R 18 as well as other ASTM quality management system standards selected by the laboratory. The ISO/IEC 17025 assessment begins with an opening meeting and a walk-through of the laboratory. A review of each requirement in the standard is then conducted, which involves an in-depth review of the laboratory's quality management system (QMS) documentation, interviews with laboratory staff regarding their job duties and the QMS, and a thorough review of records that are required by ISO/IEC 17025. The laboratory’s QMS is also evaluated based on the criteria specified by the AASHTO Accreditation Program (AAP) for AASHTO R 18 accreditation. However, demonstrations of test methods are typically not required during the ISO/IEC 17025 assessment.

Getting Started

The process for obtaining accreditation for ISO/IEC 17025 is simple – just submit the following information:
  1. ISO/IEC 17025 Assessment Request Form:
    • Login to the AASHTO re:source website with your e-mail and password
    • Request an Assessment
    • Follow Steps 1-4 in the request, ensuring that the “Request AASHTO Accreditation” and “ISO/IEC 17025” buttons are selected in Step 2 (AASHTO R18 will be unselected)
    • Click “Submit Request”
  2. Email the following documents to info@aashtoresource.org:
    • A current copy of your laboratory’s quality manual
    • Records of your laboratory’s most recent internal audit
    • Records of your laboratory’s most recent management review

Scheduling the Assessment

Once the required information is received, a review of the laboratory's documentation takes place in the AASHTO re:source office. If the majority of the documentation requirements in the standard have been met, an on-site assessment is scheduled for a mutually agreeable date. If there are shortcomings with the documentation, AASHTO re:source staff will work with you to ensure everything is in order before an assessment is scheduled. The first assessment is typically scheduled for two to three days.

Accreditation Requirements

Each ISO/IEC 17025 assessment concludes with a preliminary report of the findings. The AAP requires that corrective actions be submitted within 90 days of the final report.

Fees and Schedule of Future Assessments

The total cost of a full assessment, for laboratories located in the continental United States, is $2500. This includes all travel costs and a $500 non-refundable deposit. Laboratories located outside of the continental United States should contact us for a cost estimate. Once a laboratory is accredited for ISO/IEC 17025, a surveillance assessment is conducted approximately one year after accreditation is granted for ISO/IEC 17025 at a cost of $1800. After that, assessments occur approximately every 27 months, alternating between full assessments ($2500) and surveillance assessments ($1800). Visit the AASHTO Accreditation Program's Fee page for a complete description of program fees.

Assessment Type Interval Cost
Full 27 months $2500
