Wash at 50 °C
Machine wash in water up to 50 °C on a normal cycle. The list GINETEX publishes for the current ISO 3758:2023 edition has no 50 °C tub, so you will mostly meet this limit on older labels and on North American labels, where it is drawn as three dots.
What to do
Few machines have a 50 °C step: pick 40 °C, which is always within the label, rather than rounding up to 60 °C.

On US and Canadian labels
North American labels draw this limit as three dots in the tub (50 °C, about 120 °F, described as hot).
Often confused with
Machine wash up to 50 °C on a gentler cycle with reduced agitation (one bar). Like the plain 50 °C tub, it is absent from GINETEX's list for ISO 3758:2023 and turns up on older and North American labels.
