Coating powders - Part 8: Assessment of the storage stability of thermosetting powders (ISO 8130-8:2021)

This document establishes a method for the estimation of the storage stability of thermosetting
coating powders. It provides the procedures for determining the changes both in the physical state
of a thermosetting coating powder and in its chemical reactivity, together with its capacity to form a
satisfactory final coating.

Pulverlacke - Teil 8: Beurteilung der Lagerbeständigkeit von wärmehärtenden Pulverlacken (ISO 8130-8:2021)

Dieses Dokument legt ein Verfahren zum Bewerten der Lagerbeständigkeit von wärmehärtenden Pulverlacken fest. Es liefert die Verfahren zum Bestimmen der Änderungen sowohl des physikalischen Zustandes eines wärmehärtenden Pulverlackes als auch seiner chemischen Reaktivität, zusammen mit dessen Fähigkeit, eine zufrieden stellende Beschichtung zu ergeben. Eine Korrelation zwischen Änderungen unterschiedlicher Eigenschaften ist nicht zu erwarten. In ähnlicher Weise braucht keine Korrelation zwischen den Ergebnissen vorhanden zu sein, die bei unterschiedlichen Lagerbedingungen erhalten wurden.
Die Ergebnisse der in diesem Dokument festgelegten Verfahren geben einen Hinweis darauf, ob ein Pulverlack den Einflüssen durch eine Lagerung vor dem Auftragen standhält.

This document was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee

This second edition cancels and replaces the first edition (ISO 8130-8:1994), which has been technically

revised. The main changes compared to the previous edition are as follows:
a) Clause 3 on terms and definitions has been added;

b) pretreated aluminium panels have been added in Clause 6 as another option for test panels;

c) Table 1 describing four different ratings for the extent of compaction of agglomeration of the

coating powder has been deleted;

d) the required supplementary information (former Clause 4 and Annex A) has been incorporated in

the test report;

e) the text has been editorially revised and the normative references have been updated.
