B31E FOREWORD "Seismic design of critical piping systems is often required by Building Codes or by regulation, or it may be voluntarily instituted for loss prevention and worker and public safety.

While seismic loads are mentioned in the various sections of the ASME B31 Pressure Piping Code, and allowable stresses are provided for occasional loads, there has been a need to provide more explicit and structured guidance for seismic design of new piping systems, as well as retrofit of existing systems. In order to respond to this need, this Standard was prepared by the ASME B31 Mechanical Design Technical Committee"

PS. You may address a letter to the Committee just to say them you have not such needs...
