ISO 22553-9-2020 Paints and varnishes – Electrodeposition coatings – Part 9: Baking loss

ISO (International Organization for Standardization) is the global federation of national standards bodies (ISO member bodies). The development of international standards is usually carried out through ISO technical committees. Each member group interested in a subject on which a technical committee has been established has the right to be represented on the Committee. International, governmental and non-governmental organizations in liaison with ISO are also involved in this work. ISO works closely with the International Electrotechnical Commission (IEC) on all matters of electrical standardization.

Part 1 of the ISO/IEC Directive describes the procedures used to develop this document and for further maintenance. In particular, note the different approval standards required for different types of ISO documents.

ISO 22553-9-2020 Paints and varnishes – Electrodeposition coatings – Part 9: Baking loss

Baking loss of electrodeposited coatings is not an absolute parameter, but depends on the temperature used during the test and the duration of the test. Therefore, when using this method, only the relative value and not the true value of the drying loss can be obtained.

Relative mass loss factors, relative reaction loss factors and relative total bake loss factors can be calculated relative to coated and ventilated, pre-dried and baked test plates. Calculations are specified in Appendix A.

1 Scope of application
This document specifies a method for determining the volatile content of electrodeposition coatings (electrophoretic paints) used in the automotive industry and other general industrial applications (e.g. chiller, consumer goods, radiators, aerospace, agriculture) during baking (baking loss).
