BS EN ISO 15797:2018,Textiles – Industrial washing and finishing procedures for testing of workwear.BS EN ISO 15797:2018 pdf free download here.
BS EN ISO 15797:2018 specifies test procedures and equipment which can be used in the evaluation of workwear (including, where appropriate, for some PPE garments) intended to be industrially laundered. They serve as a basis for testing relevant properties such as dimensional stability, colour characteristics, creasing, seam puckering, pilling and visual aspects in general.
BS EN ISO 15797:2018 does not provide instructions and specifications for the procedures and equipment to be used by industrial launderers.
This document 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.
It is not practical to carry out rigorous testing in an industrial laundry environment and this document, using intermediate stage equipment, allows testing to be done in a more exacting laboratory setting under standardized conditions.
This document is a test method and is 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.
A laundering cycle consists of a washing and a drying/finishing procedure.

The specimen (or relevant number of specimens) is washed in a washer/extractor and dried/finished according to one of the specified procedures. If multiple laundering cycles are required, each wash process shall be followed by drying/finishing.
