Sets out the requirements for air handling systems which ventilate enclosures by mechanical means. It sets minimum requirements for preventing an excess accumulation of airborne contaminants, or objectionable odours. It does not prescribe other requirements associated with comfort such as temperature, humidity, air movement or noise. The Standard also includes requirements for natural ventilation at carparks. Road tunnels are not addressed in this Standard.

Scope

This Standard sets out requirements for air-handling systems which ventilate enclosures by mechanical means, where such systems are required by a Regulatory Authority. It sets minimum requirements for preventing an excess accumulation of airborne contaminants, or objectionable odours. These minima are based on needs for body odour control, food odour control, air contaminant control, or carbon dioxide concentrations or a combination of any or all of these factors, depending on the particular situation. It does not prescribe other requirements associated with comfort, such as temperature, humidity, air movement or noise. This Standard also includes requirements for natural ventilation of carparks. Road tunnels are outside the scope of this Standard.
NOTES:
1 Fire-safety aspects related to air-handling systems are covered in AS 1668.1.
2 It is recommended that air-handling systems be designed, constructed and installed so that their use does not give rise to a nuisance arising from noise or vibration. For guidance on noise and vibration control see AS 1055 and AS 2107.
