IS 2556 Part 9: Load Bearing Test for Bidets

Key Specifications (Clause 8.05)

• Load Applied: 400 ± 8 kgf (equivalent to 4 ± 0.08 kN)
• Load Application:
  • Load placed on a wooden beam (cross-section: 100 mm × 100 mm)
  • Beam positioned across the center of the top opening of the bidet
• Duration: Load applied continuously for 1 hour
• Acceptance Criteria: No damage or defect shall occur to the bidet after the test

Summary Table

Additional Notes

• Fix bidet securely on floor with proper screws before testing.
• Follow IS 2556 Part 1 for dimensional tolerances.
• Sampling and inspection procedures follow IS 9140.
• Round off numerical values per IS 2:1960 rules.

This ensures structural integrity and durability of bidets under specified load conditions.

IS 2556 Part 9 refers to sampling, inspection, and lot inspection for vitreous china sanitary appliances, directing users to IS 9140 for detailed procedures.

Key Points:

• Sampling & Inspection: Follow IS 9140 guidelines for:

  • Sampling size
  • Inspection levels (e.g., normal, tightened)
  • Acceptable quality levels (AQL)
  • Lot acceptance criteria

• Lot Inspection: Determines acceptance or rejection of a batch based on sample testing.

• Rounding Off Results:
  Use IS 2:1960 rules for rounding test results to the same decimal places as specified values.

Summary Table (from IS 9140):

Load Test Example (Clause 8.05):

• Apply 400 ± 8 kg (≈ 4 ± 0.08 kN) load for 1 hour on a 100 mm × 100 mm wooden beam across bidet opening.
• No damage or defects allowed.
