Practical Notes
This 1984 version has been superseded by IS 11117:2019; the latest version should be used for all new designs and procurement.
When procuring, verify that the rod coupling mechanism is compatible with existing inventory.
The machine's dimensions and weight are critical for ensuring it can be deployed effectively in dense urban areas with limited manhole access.
