The system has been tested, and it complies with the specific requirements of the British Standards EN1859:2000 Resistance against rainwater (clause 4.92), and EN1846-1:2003 Performance when subject to wind resistance (Annex NA.6). In achieving these standards, the terminal protects from internal accumulation of rainwater, and gives low resistance air passage, which aids in the effectiveness of Passive Stack ventilation.
