About This Item


Full Description

This standard was created to provide an accepted method for verifying the seismic capabilities of seismic restraints. The need for such a method was recognized in ASHRAE’s A Practical Guide to Seismic Restraint, and ASHRAE Technical Committee 2.7, Seismic and Wind Restraint Design, proposed that this standard be developed. Currently the manufacturers of seismic restraints test their products in different ways. The aim of this standard is to give architects, engineers, and manufacturers a common method of determining the capabilities of seismic restraints.
