Specifies requirements for access covers and grates for use in vehicular and pedestrian areas. It applies to single or multi-part access covers and grates, where any single cover does not exceed 1300mm clear opening. Covers products manufactured from grey and ductile iron, cast and manufactured steel, aluminium, concrete, and polymeric materials.
This Standard was prepared by the Standards Australia Committee CE-029, Access Covers and Grates, to supersede AS 3996—2006.
The objective of this Standard is to provide designers, manufacturers and purchasers of access covers and grates with a specification for design, supply and testing.
This revision has been made to improve performance of trafficable covers and grates, to provide a method of testing uplift and to include specific requirements for composite materials.
