Important Specification:

Additional Notes:

• The standard builds on and references other parts of IS 13630.
• For detailed formulas or tables, consult respective clauses in the full standard text.

IS 13630 Part 3 — Definitions (Clause 2.1)

• This clause provides standardized definitions for terms used in the code, ensuring uniform interpretation.
• Definitions are aligned with ISO 13006:1998, which covers ceramic tiles' classification, characteristics, and marking.
• No specific formulas or tables are provided in this clause; it focuses on terminology clarity.
• For test results and calculations, rounding off must follow IS 2:1960 rules:
  • Round final values to the same number of significant figures as specified.
  • Ensures consistency and accuracy in reporting compliance.

Key Points:

This ensures clarity and consistency in interpreting measurements and compliance criteria.

IS 13630 Part 3 – Apparatus Specifications

• Clause 3.5:
  Apparatus must maintain specimens in boiling water for 24 hours continuously. This requires a stable water bath with temperature control at 100°C ± tolerance.

• Clause 3.4:
  Linear measurements of specimens should be made using vernier calipers or equivalent, accurate to ±0.5 mm.

Key Apparatus Requirements Summary:

Notes:

• Temperature stability is critical to ensure consistent test conditions.
• Measurement accuracy affects dimensional compliance evaluation.
• Follow IS 2:1960 for rounding off test results to match specified significant figures.

    D --> F[Measure Dimensions]
    F --> G[Vernier Calipers ±0.5 mm]

This ensures test repeatability and compliance with IS 13630 Part 3.

IS 13630 Part 3: Test Specimens Key Points

• Sample Size (Clause 4.1):

  • Use 7 whole tiles per tile type.
  • Cut specimens from tile center.
  • Specimen dimensions:
    • Length: up to 100 mm (max possible)
    • Width: minimum 35 mm
    • Thickness: same as tile thickness.

• Specimen Orientation (Clause 4.2):

  • For extruded tiles, length of specimen must be along the extrusion direction.

• Initial Measurement (Clause 5.1.6):

  • Measure initial length to the nearest 0.5 mm.

• Additional Apparatus (Clause 3.5):

  • Maintain specimens in boiling water for 24 hours during testing.

This ensures uniformity and compliance for mechanical and durability testing of tiles per IS 13630 Part 3.

IS 13630 Part 3: Test Procedure - Key Points

• Rounding Off (Clause None):
  Final test results must be rounded per IS 2:1960 rules, retaining the same significant figures as the specified values.

• Boiling Water Conditioning (Clause 3.5):
  Test specimens must be maintained in boiling water for 24 hours before testing.

• Specimen Preparation (Clause 4.3):
  Ends of specimens should be prepared to fit the measuring device accurately, ensuring reliable test measurements.

Additional Recommendations (Engineering Practice):

This ensures test results are consistent, reliable, and compliant with IS 13630 Part 3.

IS 13630 Part 3: Expression of Results

Key Points from Clause 6:

• Rounding off: Final test or analysis results must be rounded as per IS 2:1960 rules.
• Significant figures: Retain the same number of significant places as specified in the standard.

Moisture Expansion Calculation (Clause 6.2):

[ \text{Moisture Expansion (mm/m)} = \frac{I}{L} \times 1000 ]

• I: Increment in length due to moisture (mm)
• L: Original length of specimen (mm)

Test Report Must Include:

• Description of tiles tested
• Moisture expansion value for each specimen

Summary Table for Expression of Results:

This ensures uniformity and clarity in reporting test results under IS 13630 Part 3.

Basis for Acceptance - IS 13630 Part 3 (referring ISO 10545-1:1995)

Key points:

• Rounding Off: Final test values must be rounded as per IS 2:1960 rules, retaining the same number of significant digits as the specified standard value.

• Moisture Expansion Calculation (Clause 6.2):
  [ \text{Moisture Expansion (mm/m)} = \frac{I}{L} \times 1000 ]
  Where:

  • (I) = Change in length (mm)
  • (L) = Original length (m)

• Test Report Must Include:

  • Description of the tile samples
  • Moisture expansion value for each specimen

Summary Table: Expression of Results

Notes:

• Acceptance criteria depend on compliance with specified limits in the relevant IS or ISO standards.
• Sampling and test methods follow ISO 10545-1:1995.
• Always verify the number of significant digits in the reported values matches the standard's specification.
