IS 2556:2020 Part 4 is the Indian Standard (BIS) for vitreous sanitary appliances (vitreous china) - urinals. This standard specifies the requirements for materials, dimensions, construction, and performance of vitreous china urinals, including bowl, half-stall, slab, and squatting types.
Specifies requirements for vitreous china urinals.

Practical Notes
! Must be read in conjunction with IS 2556 Part 1 which provides general requirements, tolerances, and testing methods for all vitreous sanitaryware.
! BIM modelers and architects should carefully reference the dimensional tables to ensure correct rough-in dimensions for plumbing pipelines.
! Flushing tests require precise alignment of spreaders and discharge pipes as specified in the constructional requirements.

Frequently Asked Questions3
What is the maximum water absorption allowed for vitreous china urinals?+
Maximum 0.5% by mass, as specified in the general requirements (IS 2556 Part 1).
What are the standard tolerances for urinal dimensions?+
Typically ±5% for dimensions above 100mm and ±5mm for dimensions below 100mm, unless explicitly stated otherwise in the specific dimension tables.
Does this standard cover electronic flush valves or sensors?+
No, this standard strictly covers the vitreous china appliance (the ceramic urinal basin/stall itself).
