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 20567-2 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 9,
General test methods for paints and varnishes.
ISO 20567 consists of the following parts, under the general title Paints and varnishes — Determination of
stone-chip resistance of coatings:
 Part 1: Multi-impact testing
 Part 2: Single-impact test with a guided impact body

Introduction
In the automobile industry, multi-layer paint coatings are applied to car bodies for protection. Grit, road-metal
and other materials can damage these coatings in such a way that individual layers come off or the whole
coating delaminates from the substrate.
Stone chipping can be simulated by means of single- and/or multi-impact tests. Part 1 of this International
Standard describes multi-impact testing, Part 2 describes a single-impact test.
This part of ISO 20567 is based on the German Standard DIN 55996-2:2001, Beschichtungsstoffe — Prüfung
