What is ISO 8130-8 about?
ISO 8130 discusses coating powders. ISO 8130-8 is the eight-part of ISO 8130 multi-series and discusses the assessment of the storage stability of thermosetting powders. ISO 8130-8 specifies a method for the estimation of the storage stability of thermosetting coating powders.
ISO 8130-8 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.
Who is ISO 8130-8 for?
ISO 8130-8 on coating powders is useful for:
- Paint Manufacturers
- Quality control personnel
Why should you use ISO 8130-8?
Coating powders are subject to two distinct ageing mechanisms, one involving the physical state of the powder and the other its chemical reactivity. Changes in the coating powder may lead to deterioration in the physical and chemical properties of the final coating.
ISO 8130-8 describes the procedures to be adopted in assessing the tendency of a thermosetting coating powder to maintain its physical and chemical integrity after being subjected to defined storage conditions. The results of the procedures in ISO 8130-8 give an indication of the ability of the coating powder to withstand the effects of storage prior to application.
What’s changed since the last update?
BS EN ISO 8130-8:2021 supersedes BS EN ISO 8130-8:2010, which is withdrawn. BS EN ISO 8130-8:2021 includes some technical changes with respect to BS EN ISO 8130-8:2010. These include:
- Clause 3 on terms and definitions has been added
- Pretreated aluminium panels have been added in Clause 6 as another option for test panels
- Table 1 describing four different ratings for the extent of compaction of agglomeration of the coating powder has been deleted
- The required supplementary information (former Clause 4 and Annex A) has been incorporated in the test report<
- The text has been editorially revised, and the normative references have been updated
