Where this symbol comes from

This is a North American (ASTM D5489 / Canadian guide) meaning. On ISO labels the tub always carries a temperature, a hand or a cross; GINETEX's list has no empty-tub instruction.

Often confused with

The item can be machine washed in water up to 95 °C on a normal, full-agitation cycle. It is the hottest wash any care label allows — in practice a boil wash for sturdy whites.
