DIN EN ISO 15797:2017-03

This standard enables manufacturers of textiles to test their fabrics and garments for resistance to exacting washing and drying processes used in industrial laundries for care and maintenance purposes. This standard defines test methods to simulate the effect of industrial laundering on workwear to be used when assessing textile properties such as dimensional stability, colour characteristics, creasing, seam puckering (and pilling). It may be used where appropriate for PPE. It is not practical to carry out rigorous testing in an industrial laundry environment and this International Standard, using intermediate stage equipment, allows testing to be done in a more exacting laboratory setting under standardised conditions. This standard is a test method and not intended as instructions or recommendations on how to wash and dry in an industrial laundry. Nor does it provide specifications on equipment to be used by industrial launderers. This standard defines 8 options for washing (front- or side-loading horizontal rotating drum type washer/extractor) and 2 options for drying procedures (tumble drying and tunnel/cabinet finishing) to choose from. Preferably one washing and one drying procedure should be used - those which are best suited to the characteristics of the fabric or fabric blends. It is not necessary to test using all 8 washing procedures, nor both drying procedures. A laundering CYCLE consists of a washing and a drying/finishing procedure. Identification of patent holders, if any.
