Cleanability Test as per IS 2556 Part 6

• Test Setup:

  • Urinal (squatting plate or bowl) mounted in normal position.
  • Use a 0.1% organic dye solution to smudge the interior flushing surface below flush holes or spreader.
  • Flush with 2.5 litres of water poured along flush holes (squatting plate) or flushed via automatic cistern (bowl urinal).

• Flushing Details (Clause 12.5):

  • Bowl urinal mounted vertically.
  • Use a 12.5 mm bore spreader fixed flush with back plate, slot washing downwards.
  • Automatic flushing cistern of 2.5 litres capacity per IS 2326:1987 with 20 mm flush pipe.
  • Height from cistern bottom to spreader/inlet socket ≥ 90 cm.

• Acceptance Criteria:

  • After flushing, no dye color should remain on the interior flushing surface.
