    Describes a system for designating the quantity and size of defects and the intensity of changes in appearance of coatings and outlines the general principles of the system used throughout ISO 4628.

    Scope - (Show below) - (Hide below)

    This part of ISO4628 defines a system for designating the quantity and size of defects and the intensity of changes in appearance of coatings and outlines the general principles of the system used throughout ISO4628 . This system is intended to be used, in particular, for defects caused by ageing and weathering, and for uniform changes, for example yellowing. The other parts of ISO4628 provide pictorial standards or other means for evaluating particular types of defect. As far as possible, already existing evaluation schemes have been used as the basis. This part of ISO4628 is also used for assessing defects not covered by the other parts of ISO4628 .
