1   Scope

This part of ISO 16276 specifies procedures for rating the resistance of coating systems when a cut in the form of a right-angle lattice pattern (cross-cut) or in the form of an X (X-cut) is made into the coating, penetrating through to the substrate.
This part of ISO 16276 is only applicable if the cross-cut or X-cut test method is specified, together with the rating from the appropriate rating scale.

NOTE The characteristics of the coating can make the assessment of the result of a cross-cut or X-cut test difficult.

This part of ISO 16276 also specifies suitable equipment and defines inspection areas, sampling plans and acceptance/rejection criteria.
It does not specify ratings for particular coating systems.
