What is the specific scope of this section?

It covers only the specific dimensional, functional, and tolerancing requirements for stall-type urinals made of glazed fire-clay.

Where are the material testing requirements like water absorption and crazing found?

General material requirements and testing methods are specified in the overarching IS 771 (Part 1).

Why specify glazed fire-clay (IS 771) instead of vitreous china (IS 2556)?

Glazed fire-clay is more robust, thicker, and highly resistant to impact, making it ideal for heavy-duty or vandalism-prone public washrooms.

This standard specifies the dimensional and manufacturing requirements for glazed fire-clay stall urinals. It is primarily used by MEP engineers, architects, and manufacturers to specify durable sanitary fixtures for high-traffic public, commercial, and industrial restrooms.

Quick Reference Values

Dimensional tolerance for size greater than 100 mm± 4 percent

Dimensional tolerance for size up to 100 mm± 5 mm

Practical Notes

This section must be read in conjunction with IS 771 (Part 1), which details the general material, testing, and glazing requirements for all fire-clay sanitary appliances.

Glazed fire-clay fixtures are significantly thicker and heavier than standard vitreous china, meaning they require adequate structural support and careful manual handling during site installation.
