This test fabric is soiled with a
mixture of oily components
and pigments. It is useable to
test single tensides or even
composed detergents using
gentle washing processes (e.g.
Laundrometer, “woolcycle”,
“easycare”,...).

Article 125 is sensitive to surfactants (type and concentration)
and slightly to lipases and to the washing temperature. The influence
of bleaching agents and further enzymes is considered to be very low.
Washing conditions:
16 °fH / 30 ° / 50 rpm
/ 800 ml washing
liquor / 40 g cottonballast
