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

Introduction
ISO 22762 series includes two parts related to specifications for isolators, i.e. ISO 22762-2 for bridges
and ISO 22762-3 for buildings. This is because the isolator requirements for bridges and buildings are
quite different, although the basic concept of the two products is similar. Therefore, ISO 22762-2 and
the relevant clauses in ISO 22762-1 are used when ISO 22762 (all parts) is applied to the design of bridge
isolators whereas ISO 22762-3 and the relevant clauses of ISO 22762-1 are used when it is applied to
building isolators.
The main differences to be noted between isolators for bridges and isolators for buildings are the
following.
a) Isolators for bridges are mainly rectangular in shape and those for buildings are circular in shape.
b) Isolators for bridges are designed to be used for both rotation and horizontal displacement, while
isolators for buildings are designed for horizontal displacement only.
c) Isolators for bridges are designed to perform on a daily basis to accommodate length changes of
bridges caused by temperature changes as well as during earthquakes, while isolators for buildings
are designed to perform only during earthquakes.
d) Isolators for bridges are designed to withstand dynamic loads caused by vehicles on a daily basis as
well as earthquakes, while isolators for buildings are mainly designed to withstand dynamic loads
caused by earthquakes only.
For structures other than buildings and bridges (e.g. tanks), the structural engineer uses either
ISO 22762-2 or ISO 22762-3, depending on the requirements of the structure.

Elastomeric seismic-protection isolators —
Part 3:
Applications for buildings — Specifications
1 Scope
This document specifies minimum requirements and test methods for elastomeric seismic isolators
used for buildings and the rubber material used in the manufacture of such isolators.
It is applicable to elastomeric seismic isolators used to provide buildings with protection from
earthquake damage. The isolators covered consist of alternate elastomeric layers and reinforcing steel
plates. They are placed between a superstructure and its substructure to provide both flexibility for
decoupling structural systems from ground motion, and damping capability to reduce displacement
at the isolation interface and the transmission of energy from the ground into the structure at the
isolation frequency.

performance.
6 © ISO 2018 – All rights reserved

5.2 Classification by construction
Elastomeric isolators are classified by construction, as shown in Table 2.
Other methods not listed in Table 2 may be used to fix flanges to the laminated rubber, if the resulting
construction has adequate strength to resist the shear forces and bending moments due to shear
deflection. Furthermore, such constructions shall be capable of resisting tension if the elastomeric
isolator is designed for uplift.

S-A ±15 % ±10 %
S-B ±25 % ±20 %
6 Requirement
6.1 General
Elastomeric isolators for buildings and the materials used in manufacture shall meet the requirements
specified in this clause. For test items (see Table 4) that have no specific required values, the
manufacturer shall define the values and inform the purchaser prior to production.
The standard temperature for determining the properties of elastomeric isolators is 23 °C or 27 °C
in accordance with prevailing International Standards. However, it is advisable to establish a range
of working temperatures taking into consideration actual environmental temperatures and possible
changes in temperatures at the work site where the elastomeric isolators are installed.

If double-shear test configuration used, 2 tests shall be performed.
Some of these properties may be determined using one of the standard test pieces detailed in Tables 10
and 11 in ISO 22762-1:2018. The standard test pieces are used for non-specific product tests, such as
testing in the development of new materials and products.
6.2 Type tests and routine tests
6.2.1 Testing to be carried out on elastomeric isolators is classified into “type tests” and “routine tests”.
6.2.2 Type tests shall be conducted either to ensure that project design parameters have been achieved
(in which case the test results shall be submitted to the structural engineer for review prior to production)
or to verify isolator performance and material properties during development of the product. The test
piece for each type test shall be full-scale or one of the options specified in Table 4. The test piece shall
not have been subjected to any previous test programme. The tests shall be performed on test pieces
not subjected to any scragging, unless the production isolators are to be supplied after scragging. In that
case, the test pieces shall be subjected to the same scragging procedure as the production isolators.
6.2.3 Previous type test results may be substituted, provided the following conditions are met.
a) Isolators are fabricated in a similar manner and from the same compound and adhesive.
b) All corresponding external and internal dimensions are within 10 % of each other. Flange plates
are excluded.
c) First and second shape factors are equal to or larger than those in previous tests.
d) The test conditions, such as maximum and minimum vertical load applied in the ultimate property
test (see 6.5.7), are more severe.
Routine tests are carried out during production for quality control. Sampling is allowed for routine
testing for projects with agreement between structural engineer and manufacturer. Sampling shall be
conducted randomly and cover not less than 20 % of the production of any isolator design. For a given
project, tests shall cover not less than four test pieces for each size and not less than 20 test pieces in total.
If isolators are supplied after scragging, the routine test shall be performed on scragged isolators.
6.3 Functional requirements
Elastomeric isolators for buildings are designed and manufactured to have the performance
characteristics required so that they deform in all directions with the proper stiffness (with damping,
if required) during an earthquake.
In the application of elastomeric isolators, attention shall be paid to the following points.
a) The isolators shall be installed horizontally between the structure and foundation.
b) Once installed, the isolators shall not be subjected to a constant shear force.
c) When isolators are to be installed under relatively flexible columns, the rotation at the top of the
isolator caused by bending deformation shall be carefully considered.
d) Exposed steel surfaces, such as the surfaces of mounting flanges, shall be properly painted or
galvanized to prevent rusting.
e) Proper maintenance shall be carried out on installed isolators to prevent any abnormalities such as
distortion, cracks or rust occurring.
f) Fire protection of the isolators may be required.
g) The seismic gap shall be maintained at all times.
6.4 Design compressive force and design shear displacement
6.4.1 The design stress and strain of an isolator are defined by the following relationships with the
design force and the displacement.

The isolators shall be tested and the results recorded using the specified test methods. They shall
satisfy all of the requirements listed below. The test items are summarized in Table 5, which indicates
those type tests that are optional, where a material test piece may substitute an isolator, and the tests
to be performed as routine tests. The standard value obtained from the tests shall be reported. Double-
shear configuration testing (see ISO 22762-1:2018, 6.2.2.2) can be employed with the approval of the
structural engineer.
