Is there a clear definition for “homogeneous material” according to the ELV directive?
Ans: Yes. This can be shown using the example of a multiple coated screw. Each layer on its own is defined as a “homogeneous material”. This means that a screw [whose metal body is coated with a zinc alloy, followed by a passivation layer, finished by a ‘top coat’] has four homogeneous materials: the body of the screw and three homogeneous coating layers.
