This Standard sets out a classification system for wiring system elements. The classification
is according to the wiring system’s ability to:
(a) maintain circuit integrity under fire conditions for a specified period; and
(b) maintain circuit integrity against mechanical damage of specified severity.
It  specifies  type  tests  to  classify  the  performance  of  the  various  types  of  wiring  system  elements.

If an assembled wiring system is tested to this Standard, the classification achieved cannot
be assigned to any one of its individual elements. The wiring system classification achieved
shall only be applicable to the assembled wiring system as tested.

This Standard does not address the screening function of screened cables after exposure to
fire conditions.

NOTE: Elements of a wiring system might need replacement after exposure to fire conditions or
mechanical damage.
