1.1 This International Standard specifies standardized washing and drying procedures for textile testing. The
procedures are applicable to textile fabrics, garments and other made-up textile articles which are subjected to
appropriate combinations of domestic washing and drying procedures.
1.2 Provision is made for:
a) ten different washing procedures based on the use of a horizontal drum, front loading type machine (type A
washer).
This amendment allows for the use of a replacement of the horizontal drum machine and the machine specified in
previous additions of this International Standard. The original machine is no longer manufactured.
Limited trials carried out indicate that tested fibre and fabric types in both machines give similar results under the
same wash conditions.
b) eleven different washing procedures based on the use of top loading agitator type of machine (type B washer).
The results obtained in the two types of machine, horizontal and vertical, may not be the same.
1.3 Each washing procedure represents a single domestic wash.
1.4 This International Standard also specifies five drying procedures:
A -- Line dry
B -- Drip dry
C -- Flat dry
D -- Flat press
E -- Tumble dry
1.5 A complete test consists of a washing and drying procedure.
