This document specifies minimum requirements and test methods for elastomeric seismic elastomeric isolators used for buildings and the rubber material used in the manufacture of such elastomeric isolators.

It is applicable to elastomeric seismic elastomeric isolators used to provide buildings with protection from earthquake damage. The elastomeric 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 deflection at the isolation interface and the transmission of energy from the ground into the structure at the isolation frequency.
