Test Method: SATRA TM185
Resistance to water spotting of leathers, textiles and coated fabrics
This method is intended to determine the resistance of a material to spotting by water. Effects such as marking, staining, blistering and colour change are assessed. The method is mainly applicable to leathers, textiles and coated fabrics.
Two drops of water are placed on the test specimen. After 30 minutes surplus water is blotted from one of the drops and any visible effects are observed. The other drop is left to evaporate for 16 hours and any visible effects on this and the specimen that had been blotted after 30 minutes are observed. Changes in colour are also assessed on both dried spotted areas using a grey scale.
