Vitreous Sanitary Appliances (Vitreous China) -, Part 17: Specific Requirements of Wall Mounted Bidets
2001 Edition

Overview of Key Dimensions and Specifications

1. Functional Dimensions (Referenced in Table 1, Clause 6.1)

2. Connecting Dimensions (Referenced in Table 2, Clause 6.1)

Important Standards and Specifications Referenced

• The standard incorporates various current Indian Standards for consistency; users should consult the latest versions for compliance.

• Dimensions are categorized as:

  • Functional (non-connecting) dimensions essential for product usage.
  • Connecting dimensions critical for plumbing and fixture compatibility.

• Both categories are detailed in Tables 1 and 2 respectively.

• Numerical results from calculations or tests must be rounded following IS 2:1960, maintaining the original number of significant figures.

Load Testing Specifications for Wall Mounted Bidets

Test Parameters (Clauses 8.1 & 8.2)

• Load Magnitude: 400 ± 5 kg (equivalent to 4 ± 0.5 kN).
• Test Duration: 1 hour.
• Load Application Method:
  • A wooden beam measuring 100 mm by 100 mm is placed across the bidet’s top opening.
• Fixing Conditions:
  • The bidet must be securely installed on a smooth surface using mortar or facing material behind it.

Acceptance Criteria

• The bidet and its fastenings should remain free from damage or defects after the test.

Relevant Dimensions from Standards

• Maximum Length: 600 mm
• Breadth: 360 ± 20 mm
• Height: 350 ± 10 mm
• Fixing Hole Spacing: 230 ± 5 mm
• Fixing Hole Size (Elliptical): (30 × 25) ± 3 mm

Additional Notes

• Recommended fixing bolt diameter: 14 ± 2 mm
• Minimum clearance from bidet bottom to finished floor: 40 mm

This test guarantees mechanical robustness and secure installation.

Sampling, Process Inspection, and Lot Inspection Protocols

• Reference: Inspection procedures align with IS 9140, which details sampling based on attributes.

• Sampling Principles:

  • Sample sizes depend on lot quantity and acceptable quality levels (AQL).
  • Inspection is attribute-based, focusing on compliance (pass/fail).
  • Lot acceptance is contingent on the number of defective units found.

• Process Inspection:

  • Continuous quality monitoring throughout manufacturing.

• Lot Inspection:

  • Final evaluation of product batches before release.

• Rounding of Numerical Data:

  • Follow IS 2:1960 for rounding, keeping consistent significant figures.

Sample Table Example from IS 9140

Note: Actual sampling depends on AQL and inspection levels chosen.
