Practical Notes

This standard has been declared 'Withdrawn' by BIS. Users should verify current industry practices or manufacturer specifications before procurement.

The selection of the appropriate tool is critical for effective sewer cleaning, depending on the nature of the blockage (e.g., grease, roots, solid waste).

Proper heat treatment to achieve the specified hardness on cutting edges is essential for the durability and effectiveness of the tools.
