There is no current Australian Standard that specifically deals with trench drains.

AS 3996 specifies the requirements for access covers and grates for use in vehicular and pedestrian areas for a clear opening up to 1,300mm. The only standard written specifically for grated trench drains that is internationally recognised is EN 1433. This standard includes different grate widths and different channel sizes.

The Standard EN 1433 specifies test methods with loads up to 900kN for both the grate and channel body. The test accounts for both serviceability and ultimate loading
