Normal operation
operation of the appliance under the following conditions
Helmet-type hairdryers are operated with the axis of the hood inclined at an angle of 60° to the horizontal or the maximum angle allowed by the construction if this is less. A dull black-painted wooden sphere, 200 mm in diameter, is placed in the hood so that its centre coincides
with the axis of the hood, the shortest distance between the sphere and the air-outlet grille
being 50 mm.
Hairdryers having a flexible hood attachment are operated with the hood attachment placed over the wire frame of Figure 101, the frame being positioned over the wooden sphere.
NOTE 101 Helmet-type hairdryers that are supported by the head are operated as hairdryers having a flexible hood attachment.
Hand-held hairdryers are operated with unrestricted airflow directed downwards.
Permanent-wave appliances are operated in the normal position of use, the curling rollers hanging freely.
