• 13.220.50 Fire-resistance of building materials and elements

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.

Products/elements for use in ventilation systems include (excluding smoke and heat exhaust ventilation):

— fire resisting ducts;

— fire dampers.

Products /elements for use in/as cables systems:

— intrinsic fire resistant cables/unprotected cables;
