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 on 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 the following URL: www.iso.org/iso/foreword.html.
The committee responsible for this document is 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 20567-1:2005), which has been technically
revised with the following main changes:
— a table with the particle size distribution of the grit material has been added;
— a note concerning the use of actual pressure gages has been added to Figure 2;
— the clause on sampling has been deleted;
— the description of suitable methods for removal of loose paint have been transferred to an informative
annex as examples and, for the method using adhesive tape, the adhesive strength of the tape is no
longer specified;
— this document is revised editorially and the normative references have been updated.
A list of all parts in the ISO 20567 series can be found on the ISO website.

ISO 20567-1:2017(E)
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. ISO 20567-1 describes
multi-impact testing; ISO 20567-2 and ISO 20567-3 describe single-impact tests.
NOTE A recommended procedure for calibration of the apparatus is given in Annex B. Note that this annex
is informative because the method described in it is not the only one suitable for checking whether a uniform
impact pattern is produced.
