The Independent Laboratories Round Trials Group (ILRT) Members represent
the largest independent wool testing laboratories in the world, and are
collectively responsible for the testing of approximately 40% of the world's
greasy wool production, and in excess of 80% of all greasy wool tested.
The ILRT Group conducts regular inter-laboratory round trials on samples
of raw wool and collates the results of these trials so that each member
laboratory can compare its results with the grand mean of all the results
from all member laboratories.
The ILRT group provides a summary report of the round trial results to
each meeting of the International Wool Textiles Organisation (IWTO). The
degree of harmonisation between the Group Members is therefore regularly
available for inspection by all interested wool industry participants.
The Members believe that this transparency is essential in maintaining the confidence of the world wide wool industry in their IWTO Certificates. No other commercial Test Houses offer the same transparency concerning their technical performance in certifiying raw wool.
