It also incorporates the Te
25、chnical Corrigendum ISO 15797:2002/Cor. 1:2004.The main changes compared to the previous edition are as follows: in the Scope, the restriction of workwear to cotton, polyester and their blends has been removed, thereby including other fibres, and the accommodation of some PPE garments for which the
26、referenced processes are appropriate has been added; 6.5 has been added to give examples of antichlor chemicals; in 9.2, in light of experience, changes have been made to Drying procedure B tunnel and cabinet finishing; throughout Tables 1 to 4, the headings Cotton and Polyester/cotton have been rep

28、les 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 inte
29、rmediate 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 equipme
30、nt to be used by industrial launderers.A laundering cycle consists of a washing and a drying/finishing procedure.1 ScopeThis document specifies test procedures and equipment which can be used in the evaluation of workwear (including, where appropriate, for some PPE garments) intended to be industria
31、lly 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.This document does not provide instructions and specifications for the procedures and equipment to be used by in
32、dustrial launderers.As it is often not practical to reproduce industrial laundry processes (washing and drying/finishing) in a laboratory setting, this document provides an approach using defined intermediate scale equipment and exacting test procedures which can be used for the evaluation of workwe
33、ar intended to be laundered industrially.As this document 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
34、 compatibility.It is not necessary to test using all eight washing procedures nor both drying procedures. A selection is 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.2 Normative referencesThe followin
