The principle of the method specified is soaking a leather specimen and also a piece of adjacent fabric, laid against each side to be tested, in artificial perspiration solution, leaving the composite specimen under pressure for a specified time in a suitable apparatus, drying the leather specimen and adjacent fabric, and assessing the change in colour of the specimen and the staining of the adjacent fabric with the grey scales. Leathers with a finish may be tested intact or with the finish broken. The method is applicable to leather of all kinds at all stages of processing.
