ZHTest Method: SATRA TM158
Washability of footwear
June 2016 (2018)
SCOPE
This method is intended to assess the colour and dimensional stability of footwear during washing but not the ease of soil removal. The method is applicable to all types of footwear.
PRINCIPLE
The dimensions, colours and distinguishing marks of the shoes are first recorded. The shoes are then subjected to a low temperature machine wash cycle and dried. Changes in the size of the footwear are measured and changes in appearance assessed by reference to an identical shoe which has not been subjected to the washing treatment. Depending on the condition of the shoe after the first wash, it may then be subjected to further washing treatments up to a maximum of six washes with re-assessments being made after each wash. The shoe(s) are washed with a piece of multifibre fabric to assess colour transfer during the first washing first cycle.
