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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use
of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed
patent rights in respect thereof. As of the date of publication of this document, ISO had not received
notice of (a) patent(s) which may be required to implement this document. However, implementers are
cautioned that this may not represent the latest information, which may be obtained from the patent
database available at www.iso.org/patents. ISO shall not be held responsible for identifying any or all
such patent rights.

This document was prepared by Technical Committee ISO/TC 108, Mechanical vibration, shock and
condition monitoring, Subcommittee SC 6, Vibration and shock generating systems.
This second edition cancels and replaces the first edition (ISO 10813-1:2004), which has been technically
revised. It also incorporates the Technical Corrigendum ISO 10813-1:2004/Cor.1:2006.
The main changes are as follows:
— tables and figures are updated to reflect advances in typical system capability;
— selection calculations are rearranged to use values which are more likely to be available;
— a non-mathematical treatment of armature size and infrastructure requirements is included.

Introduction
To select a suitable vibration generating system is an urgent problem if it is necessary for a certain test
to purchase new test equipment or to update the equipment already available, or to choose between
equipment proposed by a test laboratory or even a laboratory itself which offers its service to carry
out such a test. A problem like this can be resolved acceptably if a number of factors are considered
simultaneously, as follows:
— the type of the test to be carried out (environmental testing, normal and/or accelerated, dynamic
structural testing, diagnosis, calibration, etc.);
— the requirements to be followed;
— the test conditions (one mode of vibration or combined vibration, single vibration test or combined
test, for example, dynamic plus climatic);
— the objects to be tested.
This document deals only with equipment to be used during environmental testing, and those selection
procedures that are predominantly to meet the requirements of this test. However, the user should
keep in mind that a specific test condition and a specific object to be tested can significantly influence
the selection. Thus, to excite a specimen inside a climatic chamber imposes limitations on the vibration
generator interface, and a specimen of a large size and/or of a complex shape, having numerous
resonances in all directions, demands larger equipment than that specified for the procedures of this
document, assuming that excitation is to be applied to the rigid body of the same mass. Unfortunately,
such aspects cannot easily be formalized and, thus, are not covered by this document.
If the equipment is expected to be used for tests of different types, all possible applications should be
considered when selecting. Other parts of ISO 10813 will address the problem of the case where the
vibration generator is acquired to be applied during both environmental and dynamic structural testing.
It is presumed in this document that the system selected will be able to drive the object under test up to
a specified level. In order to generate an excitation without undesired motion, a suitable control system
should be used. The selection of a control system will be considered in a further International Standard.
It should be emphasized that vibration generating systems are complex machines, so the correct
selection always demands a certain degree of engineering judgement. As a consequ
