Frequently Asked
Test specimens must be cut from the center of each tile, with a maximum length of 100 mm and a minimum width of 35 mm, maintaining the tile's thickness. Seven whole tiles per type should be selected. The specimen ends need to be prepared to fit measuring devices accurately, ensuring smooth and parallel surfaces for precise length measurement. Prior to testing, specimens should be conditioned by immersion in boiling water for 24 hours, and initial lengths recorded to the nearest 0.5 mm.
According to the standard, test specimens must be continuously immersed in boiling water at 100°C for a duration of 24 hours. During this period, a minimum water depth of 50 mm above the specimens must be maintained, and the specimens should not contact each other or the container's base and sides to ensure consistent exposure.
Accurate moisture expansion measurement requires a boiling water bath capable of sustaining 100°C for 24 hours, a precision linear measurement device such as vernier calipers or a micrometer with at least ±0.5 mm accuracy, specimen holders to stabilize tiles during measurement, and a thermometer to monitor water temperature. These tools ensure reliable detection of dimensional changes before and after conditioning.
Moisture expansion is determined by measuring the increase in specimen length after boiling water exposure relative to its original length. It is calculated using the formula: Moisture Expansion (mm/m) = (Length Increase ÷ Original Length) × 1000. This quantifies dimensional changes in millimeters per meter, with results rounded as per IS 2:1960 rules and documented along with tile descriptions.
This test method complements other parts of IS 13630 and ISO 10545 by focusing specifically on dimensional changes due to moisture in unglazed tiles. IS 13630 Part 1 and ISO 10545-1 provide sampling and acceptance frameworks, ISO 10545-3 addresses physical characteristics such as water absorption affecting expansion, while Part 3 measures the actual moisture-induced dimensional variation. Together, these standards provide a comprehensive quality assessment protocol for ceramic tiles.
