ISO 2812-3-2019 Paints and varnishes — Determination of liquid resistance — Part 3: Method using absorbent media

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

The procedures used to develop this document and those used for further maintenance are described in Part 1 of the ISO/IEC Directive. In particular, note the different approval standards required for different types of ISO documents. This document has been drafted in accordance with the editing rules in Part 2 of the ISO/IEC Directive (see

1 range
This document specifies a method of using absorbent media for determining the resistance of single – or multilayer coating material systems to the effects of liquid or paste products.

This method enables the tester to determine the effect of the test substance on the coating and, if necessary, to assess damage to the substrate.
