This standard specifies the material, dimensional, glazing, and performance requirements for vitreous china urinals used in sanitary installations. It covers manufacturing tolerances and flushing efficiency testing methodologies to ensure hygiene and durability.
Specifies requirements for vitreous china urinals, covering dimensions, quality, and performance.
Quick Reference Values
Maximum water absorption0.5% by weight
Dimensional tolerance for dimensions > 75 mm± 5%
Dimensional tolerance for dimensions <= 75 mm± 2 mm
Practical Notes
Always coordinate urinal dimensions with the plumbing roughing-in schedule to avoid installation conflicts.
Verify that the glazing covers all exposed surfaces and the water channel to prevent uric acid absorption and odor buildup.
Ensure adequate wall backing/support is provided for wall-hung urinal fixtures.
