Accreditations

IWTO

The International Wool Textile Organisation (IWTO) is the international body representing the interests of the world's wool-textile trade and industry.

The IWTO regulates the wool trade by licensing laboratories who offer IWTO-Certification services to the industry. Wool Testing Authority Europe is proud to be one of the few IWTO-licensed laboratories globally. IWTO Certificates can only issued by IWTO-licensed test laboratories on samples taken directly by staff or agents of that licensed laboratory who can then guarantee the accuracy and impartiality of test results. If the document does not say "IWTO Test Certificate" no guarantees of wool quality can be made.
