An international ring test has been carried out to assess the repeatability and reproducibility of the ISO 105‐C08 test, modified to employ a liquor to cloth ratio of 20;1 in place of the current specification of 50;1. The results, from ten laboratories located in six countries, indicate that no adverse consequences are to be expected from reducing the liquor ratio, with the statistical variability obtained being well within the norm for this type of wash fastness test. It is therefore recommended that the standard be modified to allow the test to be conducted at a range of liquor to cloth ratios. The work in this paper was initiated by the TCI/81 committee and is sponsored by the Society's Technical Coordination Committee.
