QUALITY ASSURANCE
1.6.1
Vibration Isolator Procurement
For each piece of machinery to be isolated from vibration, supply the
[inertia base], [machinery base], [platform], [rails], [saddles],
[vibration isolators], [seismic snubbers], and other associated materials
and equipment as a coordinated package by a single manufacturer or by the
machinery manufacturer. Select isolators that provide uniform deflection
even when machinery weight is not evenly distributed. This requirement
does not include the flexible connectors or the hangers for the associated
piping and ductwork.
1.6.2
Unitized Machinery Assemblies
Mounting of unitized assemblies directly on vibration isolation springs is
acceptable if machinery manufacturer certifies that the end supports of the
assemblies have been designed for such installation.

**************************************************************************
NOTE: Include the vibration isolation schedule on
the drawings. Provide information in project
specifications, if drawings do not show the
vibration isolation schedule. Further details may
be found in the current ASHRAE System Handbook,
Chapter entitled "Sound and Vibration Control."
Refer to TABLES 1A and 1B for vibration isolator
selection. DO NOT INCLUDE THE ENTIRE TABLES 1A AND
1B IN THE PROJECT SPECIFICATIONS.
