scope:

These test criteria are applicable for shake-table testing of electrical and medical imaging equipment subcomponent functional units per Figure 1 nomenclature. The term "subcomponent" is used herein to describe various types of equipment functionality resulting from the assemblage of equipment devices (i.e., subcomponents) and subassemblies that deliver specific electrical distribution, control, electromagnetic, and imaging functions. Subcomponent functional unit testing (i.e., child testing) per these criteria is conducted to augment equipment testing (i.e., parent testing) per ICC-ES AC156 test protocol.

Subcomponent testing assumes an equipment importance factor, I_p, greater than one, which requires post-test subcomponent functionality validation for designated seismic systems servicing critical infrastructure. Additionally, subcomponent testing per these criteria assumes that seismic qualification rationalization has been conducted to identify the subcomponents requiring testing for a given product line. This test standard provides procedures and criteria for testing subcomponents and does not provide selection criteria for type testing rationalization for electrical equipment. This test standard is not applicable for use on mechanical or architectural nonstructural components.
