IS 2556 Part 17: Key References and Specifications

• Referenced Standards:
  This part refers to various Indian Standards (IS) current at publication. Users should check for the latest editions for compliance.

• Dimensions (Clause 6.1):

  • Functional Dimensions: Non-connecting dimensions essential for product function.
  • Connecting Dimensions: Critical for plumbing connections.
    Both are tabulated in Table 1 and Table 2 respectively.

• Rounding Off (IS 2:1960):
  Numerical results must be rounded off as per IS 2:1960 rules, retaining the same number of significant digits as the specified value.

Typical Table Structure (Conceptual)

Summary:

• Use Tables 1 & 2 for dimension specifications.
• Apply IS 2:1960 for rounding test/analysis results.
• Always verify with the latest IS editions for compliance.

IS 2556 Part 17: Marking (Clause 10.2 BIS Certification Marking)

• Clause 10.2.1 states:
  Each bidet may be marked with the BIS Standard Mark to indicate conformity to IS 2556 (Part 17): 2001.

Key points on Marking:

• Marking is optional but recommended for quality assurance.
• The BIS Standard Mark confirms compliance with safety and performance requirements.
• Marking should be clear, durable, and legible on the product surface.
• No specific formulas or tables are provided for marking in this clause.
• Marking typically includes:
  • Manufacturer’s name or trademark
  • IS standard number (IS 2556 Part 17)
  • BIS certification logo (if applicable)

Summary Table for Marking:

This ensures traceability and quality assurance per IS 2556 Part 17.

IS 2556 (Part 17): 2001 - Load Test for Wall Mounted Bidets

Key Specifications (Clause 8.1 & 8.2)

• Load Applied: 400 ± 5 kg (equivalent to 4 ± 0.5 kN)
• Duration: 1 hour
• Load Application:
  • Use a wooden beam of cross-section 100 mm x 100 mm
  • Position beam across the center of the top opening of the bidet
• Fixing: Bidet fixed as per manufacturer's instructions on a smooth surface with mortar or facing material behind it.

Acceptance Criteria

• No damage or defect should occur to the bidet or its fastening after the test.

Important Dimensions (from Tables 1 & 2)

• Length (L): 600 mm max
• Breadth (W): 360 ± 20 mm
• Height (H): 350 ± 10 mm
• Distance between fixing holes (N): 230 ± 5 mm
• Fixing hole size (elliptical): (30 × 25) ± 3 mm

Notes

• Fixing bolts recommended diameter: 14 ± 2 mm
• Minimum gap from bidet bottom to finished floor: 40 mm

This load test ensures structural integrity and fastening reliability under specified load conditions.

IS 2556 Part 17: Sampling, Process Inspection & Lot Inspection

• Reference Standard:
  Sampling, process inspection, and lot inspection methods are as per IS 9140 (Sampling Procedures for Inspection by Attributes).

• Key Points from IS 9140:

  • Sampling plans are based on lot size and acceptable quality level (AQL).
  • Inspection is typically by attributes (pass/fail criteria).
  • Lot acceptance depends on the number of defective units found in the sample.

• Process Inspection:
  Continuous monitoring during manufacturing to ensure conformity with specifications.

• Lot Inspection:
  Final inspection of a batch (lot) before acceptance or rejection.

• Rounding off Results:
  Follow IS 2:1960 rules for rounding numerical values—maintain the same number of significant digits as specified.

Typical Sampling Table (from IS 9140)

Note: Actual sample size and acceptance criteria depend on the AQL and inspection level.
