UNE-EN ISO 15797:2019

1.1 This International Standard specifies test procedures and equipment which can be used in the evaluation of workwear (including some PPE garments) intended to be industrially laundered. They serve as a basis for testing relevant properties such as e.g. dimensional stability, colour characteristics, creasing, seam puckering, pilling and visual aspects in general.1.2 This International Standard does not provide instructions and specifications for the procedures and equipment to be used by industrial launderers.1.3 As it is often not practical to reproduce industrial laundry processes (washing and drying/finishing) in a laboratory setting, this International Standard provides an approach using defined intermediate scale equipment and exacting test procedures which may be used for the evaluation of workwear intended to be laundered industrially.1.4 As the standard reflects a simulation of real life industrial laundry conditions, in some cases testing of the workwear in the actual industrial laundering equipment and processes intended to be used is advisable when finally determining product and process compatibility.1.5 It is not necessary to test using all 8 washing procedures, nor both drying procedures. A selection shall be made of the washing and drying procedure(s) that are best suited to the characteristics of the fabric or fabric composition and the intended use.
