Textiles – Tests for Color Fastness
– Color Fastness to Washing: Test 1
1 Scope
This Part specifies No.1 Test of a series of five washing tests that have been
established to investigate the fastness to washing of colored textiles and which
between them cover the range of washing procedures from mild to severe.
NOTE: This method is designed to determine the effect of washing only on the color fastness
of the textile. It is not intended to reflect the result of the comprehensive laundering procedure.
2 Normative References
The following standards contain provisions which, through reference in this Standard,
constitute provisions of this Standard. At the time of publication, the editions indicated

Adjacent Fabric: Multifiber (neq ISO 105-F10:1989)
3 Principle
A specimen of the textile in contact with one or two specified adjacent fabrics is
mechanically agitated under specified conditions of time and temperature in a soap
solution, then rinsed and dried. The change in color of the specimen and the staining
of the adjacent fabric(s) are assessed with the gray scales.
