The field of Wool Testing for IANZ Laboratory Accreditation covers sampling, weighing and testing of wool for certification in New Zealand. The criteria for the accreditation by IANZ of wool testing laboratories have been developed in conjunction with the National Council of New Zealand Wool Interests.

With accreditation, wool testing laboratories receive formal recognition of their technical competence after assessment of their processes, facilities, staff and other key factors which relate to, and impact on the quality of the testing service provided.

Accreditation Criteria

IANZ Laboratory Accreditation for Wool Testing and Sampling laboratories is in compliance with NZS ISO/IEC 17025: General Requirements for the Competence of Testing and Calibration Laboratories, and specific technical criteria.
