ISO (the International Organization for Standardization) is a worldwide federation of national standards

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

Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
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.
— In 5.1.3 and in B.3.2 the tolerance for the time for the amplitude of swing to decrease from 12° to 4°
has been changed back to ±10 s, as it was in the second edition (ISO 1522:1998).
— The calibration of the pendulum has been added with a test for deformation.
— The text has been editorially revised and the normative references have been updated.

Introduction
This document considers in detail two test procedures for pendulum damping tests, König and Persoz.
The instruments embody the same principle, i.e. 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.
