The Australian Wool Testing Authority Ltd has produced a brochure, Testing the Wool Clip, which provides a comprehensive overview of its wool testing and certification services. This publication is a little dated as AWTA Ltd’s Sydney Laboratory has been closed and the brochure does not cover the introduction of NIR for determination of residual grease and dirt. Furthermore AWTA Ltd Certificates are now distributed as PDF files with printed documents on certificate stationary provided upon request.
