Note N In this subclass, an operation is considered as pretreatment or aftertreatment when it is specially adapted for , but quite distinct from, the coating process concerned and constitutes an independent operation. If an operation results in the formation of a permanent sub- or upper layer, it is not considered as pretreatment or after-treatment and is classified as a multi - coating process .
