This part of Iso 4628 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 Annex A of this part of ISO 4628 illustrate different ratings for the length of the longest filament L and the most frequent length M of the filaments. A comparison of the test panels with the 12 pictures in Annex A does not supersede the obligatory numerical assessment (method I or 2). ISO 4628-1 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…

If required, also measure the colour of a file test piece or a masked area. 7.3.3 Visual assessment Compare the contrast rating of the exposed test piece and an unexposed file test piece, and if required, a masked area, after each exposure stage, in accordance with the procedure given in ISO 105-A02. 8 Changes in other appearance properties Examine each test piece visually after each exposure stage for changes In appearance using, if appropriate, the procedure given in a relevant International Standard. Some examples of parameters used to assess change in appearance are listed in Annex B. Ozone cracking shall be assessed in accordance with ISO 143 1-1. NOTE Cracking or crazing in rubber test pieces exposed outdoors can result from light ageing as well as from ozone attack. A distinction is not always possible, particularly with light-coloured rubbers. Sunlight crazing is characterized by shallow cracks and usually occurs independently of strain, whereas a threshold strain has to be…
