Beschichtungsstoffe - Bestimmung der Beständigkeit gegen Flüssigkeiten - Teil 3: Verfahren mit einem saugfähigem Material (ISO 2812-3:2012)
Dieser Teil von ISO 2812 legt ein Verfahren zum Bestimmen der Beständigkeit einer einzelnen Schicht oder eines Mehrschichtsystems aus Beschichtungsstoffen gegen die Einwirkung von Flüssigkeiten oder pasten-förmigen Produkten mittels eines saugfähigen Materials fest.
Dieses Verfahren ermöglicht dem Prüfer, die Wirkung der Prüfsubstanz 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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 2812-3 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 9,
General test methods for paints and varnishes.
This second edition cancels and replaces the first edition (ISO 2812-3:2007), which has been technically
revised. The main changes are the following:
— the use of filter paper with a diameter of 36 mm is now permitted (see 4.4);
— depth filter sheets and laboratory filter paper have been included as examples of suitable types of
filter paper.
ISO 2812 consists of the following parts, under the general title Paints and varnishes — Determination of
resistance to liquids:
— Part 1: Immersion in liquids other than water
— Part 2: Water immersion method
— Part 3: Method using an absorbent medium
— Part 4: Spotting methods
— Part 5: Temperature-gradient oven method

INTERNATIONAL STANDARD ISO 2812-3:2012(E)
Paints and varnishes — Determination of resistance to liquids
Part 3:
Method using an absorbent medium
1 Scope
This part of ISO 2812 specifies a method, using an absorbent medium, for determining the resistance of an
individual-layer or multi-layer system of coating materials to the effects of liquids or paste-like products.
This method enables the tester to determine the effects of the test substance on the coating and, if necessary,
to assess the damage to the substrate.

The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced document
(including any amendments) applies.

ISO 15528, Paints, varnishes and raw materials for paints and varnishes — Sampling
3 Principle
A coated test panel is exposed to one or more test substances by using an absorbent medium. The effects of
the exposure are assessed in accordance with agreed criteria.
4 Apparatus and materials
Ordinary laboratory equipment and the following:
4.1 Heating cabinet, with artificial ventilation, for carrying out the test at temperatures up to 40 °C and
capable of maintaining the temperature to within ±3 °C.
WARNING — To protect against explosion or fire, products containing volatile flammable substances
should be handled with care. National regulations should be followed.
4.2 Watch glasses, with a diameter of approximately 40 mm, curved in such a way that, when placed over a
test area (see 8.3), the watch glass will not touch the filter paper or cotton wool swab, impregnated with the test
liquid, on the test area.
4.3 Petri dishes, with 60 mm diameter and 20 mm rim.
ISO 2812-3:2012(E)
4.4 Filter paper, of a type that will not be affected by the test substance used, with a diameter of approximately
25 mm or 36 mm.
NOTE 1 So-called depth filter sheets (e.g. those used for polishing automotive paint coatings in laboratory testing) have
been found suitable for this test. These sheets consist of a cellulose matrix containing a mixture of very fine kieselguhr and
perlite particles as the filtration-active substances.
NOTE 2 For most purposes, laboratory filter paper with a thickness of 1,0 mm to 1,25 mm will be suitable.
