What is the primary material used for these sinks?

Glazed fire-clay, which is chosen for its structural robustness and durability in heavy-duty hospital environments.

Where can I find the testing procedures for water absorption and crazing for this sink?

These general testing procedures are detailed in IS 771 (Part 1).

What are the standard tolerances for the dimensions of the sink?

Standard tolerances are ±4% for dimensions 75 mm and above, and ±2 mm for dimensions less than 75 mm.

Quick Reference Values

tolerance large dimensions± 4 percent for dimensions 75 mm and above

tolerance small dimensions± 2 mm for dimensions less than 75 mm

minimum thickness12 mm (typical for fire-clay appliances)

Practical Notes

This part must always be read in conjunction with IS 771 (Part 1), which details the general material requirements, glaze quality, and testing methods like crazing and water absorption.

Bed pan sinks require specialized flushing mechanisms and larger soil pipe connections compared to standard wash basins or sinks; ensure adequate service ducts are planned.
