This part of ISO 4628 specifies a method for assessing the amount of filiform corrosion developedfrom a scribed mark by measuring the length of the longest filament L and the most frequent length Mof filaments.Pictorial examples provided in Annex A of this part of ISO 4628 illustrate different ratings for thelength of the longest filament L and the most frequent length M of the filaments. A comparison of thetest panels with the 12 pictures in Annex A does not supersede the obligatory numerical assessment(method 1 or 2).ISO 4628-1 defines a system used for designating the quantity and size of defects and the intensityof uniform changes in appearance of coatings and outlines the general principles of the system. Thissystem is intended to be used, in particular, for defects caused by ageing and weathering, and foruniform changes such as colour changes, for example yellowing.
