FIELD: transport.
SUBSTANCE: invention relates to aircraft windows, particularly, to those meeting the requirements to fire resistance in compliance with heat emission test OSU 100/100. Window comprises translucent glazing panel with preset criterion of maximum rate of heat emission (PHRR) and 2 min interval of heat emission. Said panel is made of composition including copolycarbonate and bromo oligocarbonate at the ratio of 0.1112 to 1. Note here that copolycarbonate molecular structure contains not over 37% of 1,1-bis-(4-hydroxy-phenyl)-3,3,5-trimethyl cyclohexane relative to the weight of its residues.
EFFECT: possibility to form in thermoplastic state, including injection moulding and extrusion.
