This document specifies a method for assessing the amount of filiform corrosion developed from a scribed mark by measuring the length of the longest filament L and the most frequent length M of filaments.
Pictorial examples provided in AnnexA of this document illustrate different ratings for the degree of filiform corrosion. A comparison of the test panels with the 12pictures in AnnexA does not supersede the obligatory numerical assessment (method1 or2).
ISO4628-1 defines a system used for designating the quantity and size of defects and the intensity of uniform changes in appearance of coatings and outlines the general principles of the system. This system is intended to be used, in particular, for defects caused by ageing and weathering, and for uniform changes such as colour changes, for example yellowing.
