IS 11117:1984 is the Indian Standard (BIS) for requirements for power-driven rodding machine for sewers. This standard lays down the requirements for materials, construction, and performance of power-driven rodding machines used for cleaning and removing blockages from sewers. It covers the engine, frame, rods, and associated cleaning tools.
Requirements for power-driven rodding machine for sewers
| Parameter | IS Value | International | Source |
|---|---|---|---|
| Prime Mover Power | Not less than 11 kW (15 hp) continuous rating. | Not specified; performance is measured by output (e.g., pressure, flow) rather than input power. | DIN EN 1829-1 |
| Working Length | Rod reel capacity of not less than 150 m. | Typical hose reel capacity of 150-200 m for comparable truck-mounted jetters. | General Manufacturer Specifications |
| Operational Force | Push/pull thrust of not less than 1800 kgf (approx. 17.6 kN). | Not directly comparable; cleaning force is generated by water pressure, often up to 200 bar (2900 psi). | General Manufacturer Specifications |
| Operational Speed | Variable rod speed from 0 to 30 m/min. | This speed range is typical for modern mechanical rodding machines. | General Manufacturer Specifications |
| Primary Safety System | Automatic safety clutch to prevent rod breakage from excessive torque. | Pressure relief valve and/or unloader valve to prevent system over-pressurization. | DIN EN 1829-1 |
| Rod Material | Heat-treated special alloy steel. | High-tensile spring steel is the common material for rods in modern equipment. | General Manufacturer Specifications |
