Paints and varnishes — Evaluation of degradation of paint coatings — Designation of intensity, quantity and size of common types of defect — Part 1: General principles and rating schemes
Establishes a general system for designating the intensity, quantity and size of common types of defects and outlines the basic principles of the system in respect of designation of the intensity, quantity and size of defects. A uniform convention has been adopted for designating the intensity and quantity of defects: "o" denoting no defects, and "5" denoting defects so severe that further discrimination has no practical meaning. The schemes given in this document are intended to provide a system for describing, in a standard manner, test areas.
