Paints and varnishes - Determination of resistance to liquids - Part 2: Water immersion method (ISO 2812-2:2018)
This document specifies a method for determining the resistance of an individual-layer or multi-layer system of coating materials to the effects of water by partial or full immersion.
This method enables the determination of the effects of water on the coating and, if necessary, the assessment of the damage to the substrate.
Beschichtungsstoffe - Bestimmung der Beständigkeit gegen Flüssigkeiten - Teil 2: Verfahren mit Eintauchen in Wasser (ISO 2812-2:2018)
Dieses Dokument legt ein Verfahren zum Bestimmen der Beständigkeit einer einzelnen Schicht oder eines Mehrschichtsystems aus Beschichtungsstoffen gegen die Einwirkung von Wasser durch teilweises oder voll¬ständiges Eintauchen fest.
Dieses Verfahren ermöglicht es, die Wirkung von Wasser auf die Beschichtung und, falls notwendig, die Schädigung des Substrates zu beurteilen.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso
.org/iso/foreword .html.
This document was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee
SC 9, General test methods for paints and varnishes.
This third edition cancels and replaces the second edition (ISO 2812-2:2007), which has been technically
revised. The main changes compared to the previous edition are as follows:
— a terms and definitions clause (Clause 3) has been added;
— the reference to tank size has been changed to be an example only;
— the angle of the support for the test panels has been changed from 15° to 20° to 0° to 20°;
— the tolerance of the water temperature has been changed from ±1 °C to ±2 °C;
— rearranging the test panels has been amended by “if specified” because rearranging the test panels
is not always required.
A list of all parts in the ISO 2812 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www .iso .org/members .html.
