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 2812-2 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 2812-2:1993), which has been technically revised. The main changes are:

— conditioning of the coated test pieces after drying (or stoving) and ageing was deleted;

— the purity of water was changed from grade 2 to grade 3;

— the standard has been editorially revised to align with the new ISO 2812 series.

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
