Abstract
This document specifies the procedure for classification of the resistance to fire performance of construction products and building elements used as components of building service installations, using data from fire resistance tests which are within the direct field of application of the relevant test method. Classification on the basis of extended application of test results is also included in the scope of this document.
Construction products or building elements for use in ventilation systems include (excluding smoke control system):
— fire resisting ventilation ducts;
— fire dampers.
Construction products or building elements for use in or as cables systems:
— unprotected electric cables with intrinsic fire resistance;
— fire protective systems for cable systems and associated components.
Relevant test methods which have been prepared for these construction products/building elements are listed in Clause 2.
NOTE Cables associated with fire dampers are not generally covered by this document unless there is a local regulation that requires it.
