While IS 13435 Part 2 does not list detailed apparatus formulas or tables, it defines apparatus standards.

Apparatus Requirements:

• Stainless steel wire gauze with 180 mesh size as per IS 460 (Part 1):1985.
• Equipment must meet dimensions and quality standards referenced in relevant IS codes.

Additional Notes:

• Emphasizes the necessity of calibrated and standardized instruments for accurate testing.
• Consult IS 460 (Part 1) for detailed specifications of wire gauze.

Apparatus Summary:

Request specific apparatus design or calculation details for targeted guidance.

The standard designates reagents primarily for testing, emphasizing distilled water.

Key Details:

• Distilled water is the standard reagent for all testing procedures.
• Other parts (e.g., Part 4 for pH, Part 6 for alkali resistance) specify additional reagents.

Testing Examples Involving Reagents:

• pH measurement uses distilled water to prepare samples.
• Alkali resistance tests involve alkali solutions made with distilled water.

Typical pH Formula:

[ pH = -\log[H^+] ]

Alkali Resistance:

• Samples immersed in alkali solutions (e.g., sodium hydroxide) prepared with distilled water.
• Concentrations and durations detailed in IS 13435 Part 6.

Summary:

• Always utilize distilled water for reagent preparation.
• Refer to individual parts for reagent concentrations and apparatus.

IS 13435 Part 2: Sampling and Sample Preparation Guidelines

Essential Specifications:

• Sample weight approximately 100 grams, measured with ±0.1 g precision.
• Dilution with distilled water if required before testing.
• Ensures representative, homogeneous samples for evaluating solid content (per Part 1).

Sampling Instructions:

• Collect samples that accurately represent the batch and are uniform.
• Use clean, dry containers to prevent contamination.
• Thoroughly mix samples before weighing.

Preparation Summary:

This procedure ensures reliable analysis of solid content and related parameters.

Although IS 13435 Part 2 does not explicitly detail test formulas or tabulated procedures, general testing protocols for acrylic polymer waterproofing materials include:

Testing Essentials:

• Use calibrated equipment such as tensile machines, ovens for drying, thickness gauges, and water permeability test setups.
• Final results must be rounded in compliance with IS 2:1960.
• Test reports should document sample info, testing conditions, apparatus used, and measured values.

Common Test Parameters and Formulas:

Testing Conditions:

• Prepare and cure samples as outlined in IS 13435 Part 1.
• Conduct tests at ambient lab conditions (23 ±2°C, 50 ±5% RH).
• Perform multiple tests and report averaged results.

IS 13435 Part 2 does not provide explicit formulas or tables under this section but requires:

• Rounding of final values according to IS 2:1960 "Rules for rounding off numerical values (revised)."

Key Points:

• Round all observed or calculated results following IS 2:1960.
• No specific calculation formulas provided; use standard engineering practices.
• Ensure results are reported with proper significant figures and units.

IS 2:1960 Rounding Summary:

Refer to relevant IS parts for test-specific calculations.

IS 13435 Part 2: Test Precision and Number of Replications

• Perform at least two determinations per test to ensure result reliability.

• Final results must be rounded per IS 2:1960 standards.

• Though precision formulas are not specified, typical practice includes:

  • Calculating mean ((\bar{x})) of determinations.
  • Computing standard deviation (s) if multiple results exist.
  • Determining coefficient of variation (CV%) = (\frac{s}{\bar{x}} \times 100%).

• Report average values rounded as per IS 2:1960, along with the number of tests.

    E --> F[Report Final Value]

Guidelines for Reporting Results as per IS 13435 Part 2:

• All final test values must be rounded following IS 2:1960 "Rules for rounding off numerical values (revised)."

  Key rounding rules:

  • Digits less than 5 are dropped without altering the preceding digit.
  • Digits 5 or greater cause increment of the preceding digit.
  • Maintain consistent decimal places based on test precision.

• Reports should clearly mention:

  • Measured or calculated values.
  • Rounding procedures applied.
  • Units and testing conditions.

• Though the standard refers to an amendments table, detailed reporting tables are not specified.

• Always verify with latest amendments for updates.
