Methods A-Z

Polymer Diagnostics, Inc. testing and consulting laboratories are accredited by the American Association for Laboratory Accreditation (A2LA).

Accreditation from A2LA, Certificate Numbers: 0514-01 & 0514-02, denotes that PDI laboratories and operations were accredited using criteria specifically developed to determine technical competence. During this process, specialist technical assessors conducted a thorough evaluation of all factors that impact the production of testing or calibration data at PDI laboratories. The A2LA’s criteria are based on the internationally accepted standard ISO/IEC 17025, which measures:

  • Technical competence of staff
  • Validity and appropriateness of test methods
  • Traceability of measurements and calibrations to national standards
  • Suitability, calibration and maintenance of test equipment
  • Testing environment in sampling, handling and transportation of test items
  • Quality assurance of test and calibration data
