IS 11397:1985 is the Indian Standard (BIS) for attachment tools for power-driven rodding machines for sewers. This standard specifies the material, dimensional requirements, and manufacturing details for various attachment tools used with power-driven rodding machines for cleaning sewers. It covers tools such as augers, corkscrews, root cutters, and scrapers, ensuring their interchangeability and functional performance.
attachment tools for power-driven rodding machines for sewers
| Parameter | IS Value | International | Source |
|---|---|---|---|
| Primary Scope | Prescriptive specification for attachment tool design and materials. | Prescriptive specification for the maintenance process and cleaning outcomes. | DIN 1986-30 |
| Material for Cutting Blades | Medium carbon steel (e.g., Grade 40C8 of IS 1570), hardened and tempered. | High-carbon steel or alloy steel (e.g., AISI 1060, Cr-V) for higher wear resistance. | Typical Major Manufacturer Specification |
| Hardness of Cutting Edge | Specified as 45 to 50 HRC. | Typically 50 to 58 HRC, varying by tool type and quality. | Typical Major Manufacturer Specification |
| Coupling/Connection Type | Standardized threaded or pin-lock coupling to ensure national interchangeability. | Proprietary, non-interchangeable quick-connect or threaded systems (e.g., Ridgid A-Frame, General G-Series). | Market Standard |
| Applicable Pipe Sizes | Tools specified for sizes 100, 150, 200, 250 and 300 mm. | Manufacturers offer tools for a wider range, from ~50 mm to over 600 mm. | Typical Major Manufacturer Specification |
| Verification Method | Tool-level performance tests (e.g., cutting a jute bundle). | System-level verification of cleaning effectiveness, typically via post-cleaning CCTV inspection. | BS EN 752 |
