Paints and varnishes - Evaluation of quantity and size of defects, and of intensity of uniform changes in appearance - Part 10: Assessment of degree of filiform corrosion (ISO 4628-10:2024)

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 Annex A of this document illustrate different ratings for the degree of filiform corrosion. A comparison of the test 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 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.

Beschichtungsstoffe - Beurteilung der Menge und der Größe von Schäden und der Intensität von gleichmäßigen Veränderungen im Aussehen - Teil10: Bewertung der Filiformkorrosion (ISO 4628-10:2024)

Dieses Dokument legt ein System zum Bewerten des Ausmaßes von Filiformkorrosion, die von einem Ritz ausgeht, fest. Gemessen werden die Länge des längsten Fadens L und die häufigste Menge von Fadenlängen M.
Die Bildbeispiele im Anhang A dieses Dokumentes verdeutlichen unterschiedliche Einteilungen für den Grad der Filiformkorrosion. Ein Vergleich der Probenplatten mit den 12 Bildern im Anhang A ersetzt nicht die verbindliche numerische Bewertung (Verfahren 1 oder 2).
ISO 4628 1 legt ein System zum Bewerten der Menge und der Größe von Beschichtungsschäden sowie der Intensität von Veränderungen im Aussehen von Beschichtungen fest und enthält die allgemeinen Grundsätze des Bewertungssystems. Dieses System ist insbesondere für Schäden gedacht, die durch Alterung und Bewitterung hervorgerufen werden und für gleichmäßige Veränderungen wie Farbänderungen, zum Beispiel Vergilbung.

Peintures et vernis - Évaluation de la quantité et de la dimension des défauts, et de l’intensité des changements uniformes d’aspect - Partie 10: Évaluation du degré de corrosion filiforme (ISO 4628-10:2024)

Le présent document spécifie une méthode qui permet d’évaluer la quantité de corrosion filiforme qui se développe à partir d’une rayure, en mesurant la longueur du filament le plus long L et la longueur de filament la plus fréquente M.
Les exemples de clichés de l’Annexe A du présent document illustrent différentes cotations du degré de corrosion filiforme. Une comparaison des panneaux d’essai avec les 12 clichés de l’Annexe A ne remplace pas l’évaluation numérique obligatoire (méthode 1 ou 2).
L’ISO 4628-1 définit un système utilisé pour désigner la quantité et les dimensions des défauts ainsi que l’intensité des changements uniformes d’aspect des revêtements, et expose les principes de base du système. Ce système est destiné à être utilisé en particulier pour les défauts dus au vieillissement et aux intempéries, ainsi que pour les changements uniformes tels que les changements de couleur, comme le jaunissement.

Barve in laki - Vrednotenje obsega in velikosti poškodb ter intenzitete enakomernih sprememb videza - 10. del: Ocenjevanje stopnje nitaste (filiformne) korozije (ISO 4628-10:2024)

Standard ISO 4628-10:2016 določa metodo za ocenjevanje količine nitaste (filiformne) korozije, ki se razvije iz zapisane oznake z merjenjem dolžine najdaljšega vlakna L in najpogostejše dolžine vlaken M.
V slikovnih primerih v dodatku A tega dela standarda ISO 4628 so prikazane različne ocene za dolžino najdaljšega vlakna L in najpogostejše dolžine vlaken M. Primerjava preskusnih plošč z 12 slikami v dodatku A nima prednosti pred obveznim številskim ocenjevanjem (metoda 1 ali 2).
Standard ISO 4628-1 določa sistem za ugotavljanje obsega in velikosti poškodb ter intenzitete enakomernih sprememb videza premazov in določa splošna načela sistema. Ta sistem je namenjen zlasti za uporabo pri poškodbah, ki jih povzročita staranje in obraba, ter pri enakomernih spremembah, na primer spremembah barv, kot je porumenelost.
