Reazione al fuoco: esprime il comportamento di un materiale che, con la sua decomposizione, partecipa al fuoco al quale è stato sottoposto in specifiche condizioni.

Resistenza al fuoco: riguarda la capacità portante in caso di incendio, per una struttura, per una parte della struttura o per un elemento strutturale nonché la capacità di compartimentazione in caso di incendio per gli elementi di separazione strutturali (es. muri, solai, …) e non strutturali (es. porte, divisori, …).

Name Data Type Definition

Flammability Rating for this object. It is given according to the national building code that governs the rating of flammability for materials.

Combustible P_SINGLEVALUE / IfcBoolea n Indication whether the object is made from combustible material (TRUE) or not (FALSE).

IfcBuildingElement

Via d’esodo (o via d’emergenza): percorso senza ostacoli al deflusso, appartenente al sistema d’esodo, che consente agli occupanti di raggiungere un luogo sicuro dal luogo in cui si trovano. (G.1.9 comma 7)

Grado di protezione delle vie d’esodo: grado di protezione delle vie d’esodo. (S.4.5.3.1-4)
