Summary

This document specifies the test methods for determination of
a) the properties of the rubber material used to manufacture the elastomeric seismic isolators, and
b) the characteristics of elastomeric seismic isolators.
It is applicable to elastomeric seismic isolators used to provide buildings or bridges with protection
from earthquake damage. The isolators covered consist of alternate elastomeric layers and reinforcing
steel plates which 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.
