Standards Australia
Abstract
Specifies requirements for materials, construction and installation, including some aspects of performance, for flexible duct for air-handling systems in buildings and facilities.
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.
This Standard does not cover the following:
(i) Noise generation and transmission.
(ii) Exposure to damage from -
(A) transportation and handling;
(B) weather and temperature extremes;
(C) flexure cycle;
(D) chemical corrosion; and
(E) other in-service conditions specific to the installation.
(iii) Impact loading, such as -
(A) fire;
(B) earthquake;
(C) sudden stoppage of airflow; and
(E) resistance to airflow.
