AS 4254.1 Fire-resistance tests for Flexible duct – Standard
AS 4254.1：Ductwork for air-handling systems in buildings Part 1：Flexible duct
AS 4254.1 Fire-resistance tests for Flexible duct – Scope
This Standard specifies requirements for materials, construction and installation, including some aspects of performance, for flexible duct for air-handling systems in buildings and facilities. It covers—
a) dimensional stability (deformation and deflection) under positive or negative pressure applications and static loads;
(b) leakage under positive or negative pressure;
(c) support; and
(d) fire hazard requirements.
