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 of the voluntary nature of standards, 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
www.iso.org/iso/foreword.html.This document was prepared by Technical Committee [or Project Committee] ISO/TC 35, Paints and
varnishes, Subcommittee SC 9, General test methods for paints and varnishes.This fourth edition cancels and replaces the third edition (ISO 1522:2006), which has been technically
revised.The main changes are as follows:
— Clause 3 “Terms and definitions” has been added.
— The recommendation of using metal or glass panels has been removed from 7.1 because the test
method is also usable for other substrate materials, e.g. plastics.— The precision statement of the König Pendulum in 10.1 has been corrected reflecting the test
conditions and results of the interlaboratory comparison in 2006.— The tolerance for a measure in a calibration shall always be smaller than for the determination.
Therefore, in B.3.2 the tolerance for the time for the amplitude of swing to decrease from 12° to 4°
has been re-changed to ± 10 s, as it was in the first edition (ISO 1518-1:1998).— The text has been editorially revised and the normative references have been updated.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction
Two test procedures are considered in some detail, namely those of König and Persoz. The instruments
embody the same principle — that the amplitude of oscillation of a pendulum touching a surface
decreases more rapidly the softer the surface — but differ in respect of dimensions, period and
amplitude of oscillation.The interaction between the pendulum and the paint film is complex, depending as it does on both
elastic and viscoelastic properties, and it is not possible to establish a general relationship between
results obtained by the two tests. Therefore, only one type of pendulum should be used in a given series
of measurements of damping time.The following considerations may serve as a guide when considering which pendulum may offer an
advantage for a particular purpose.a) On surfaces with a low coefficient of friction, the Persoz pendulum may skid, which would invalidate
results; however, this occurs only rarely with paints and varnishes.b) It should be noted that both instruments reflect the sensitivity of the physical properties of a paint
to its environment, and the test therefore should be under controlled conditions of temperature
and humidity and in the absence of draughts. The thickness of the paint film and the nature of the
substrate may also affect the damping times.© ISO 2022 – All rights reserved
