International Standards are drafted in accordance with the rules given in the ISO/lEC 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. IsoO shall not be held responsible for identifying any or all such patent rights. ISO 9117-3 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 9, General test methods for paints and varnishes. This first edition of ISO 9117-3 cancels and replaces ISO 1517:1973, which has been technically revised. The main changes are as follows: a) the method has been integrated into the IsO 9117 series as Part 3, for determination of the drying of paints and varnishes; b) a “principle" clause has been added; Iso 9117 consists of the following parts, under the general title Paints and varnishes - Drying tests Part 1: Determination of through-dry state and through-dry time Part 2: Pressure test for stackability Part 3: Surface-drying test using ballotini The following parts are under preparation: Part 4: Test using a mechanical recorder Part 5: Modified Bandow-Wolff test @ ISO 2010 - All rights reserved ii INTERNATIONAL STANDARD ISO 9117-3:2010(E) Paints and varnishes Drying tests - Part 3: Surface-drying test using ballotini 1 Scope This part of isO 9117 specifies a test method for determining the surface-drying characteristics of a coating of a paint or varnish which dries by the action of air or by chemical reaction of its components. The method is not intended to apply to stoving products. The method described may be carried out: as a “go/no go"” test, by determining the surface-drying state after a specified time, to assess compliance with a particular requirement; by determining the surface-drying state at suitable intervals until the surface-drying time is obtained. 2Normative references The following referenced documents are indispensable for the application of this document.
