Key Differences
≠IS 3464:1986 is a comprehensive standard that bundles multiple test methods (dimensions, stability, flexibility, etc.) into a single document. Modern international practice, particularly ISO, is to publish separate, highly specific standards for each individual test property.
≠The standard conditioning atmosphere in IS 3464 is 27 ± 2 °C and 65 ± 5% RH, reflecting a tropical environment, whereas most current ISO/ASTM standards specify 23 ± 2 °C and 50 ± 5% RH.
≠For flexibility testing, IS 3464 specifies bending over a single 20 mm mandrel. ISO 24344 uses a set of mandrels of various diameters, and the result is the smallest diameter the tile can be bent over without cracking, providing a more granular assessment.
≠The apparatus for dimensional measurements in IS 3464 relies on basic tools like steel rules and feeler gauges. ISO 24342 specifies more precise and purpose-built apparatus with dial gauges or digital indicators, improving repeatability and accuracy.
Key Similarities
≈The fundamental properties being evaluated are identical: dimensional accuracy (length, width, squareness), dimensional stability under heat, curling, and flexibility.
≈The core principle of the dimensional stability test is the same: measure the tile, expose it to a specified high temperature for a set duration (e.g., 80°C for 6 hours), cool it, and remeasure to calculate percentage change.
≈The concept for the flexibility test is analogous, involving bending a test specimen over a cylindrical mandrel to check for any signs of cracking or breaking on the outer surface.
≈Both the Indian and international standards require a pre-test conditioning period for the test specimens to ensure they are stabilized at a standard atmospheric condition before testing begins.
