IS 13630 : Part 14 : 2019 Ceramic Tiles - Methods of Test, Sampling and Basis for Acceptance Part 14 Determination of Impact Resistance by Measurement of Coefficient of Restitution
New Standard from Last Update.
1. SCOPE
This standard (Part 14) defines a method of test for determining the impact resistance of ceramic tiles by measuring the coefficient of restitution.
For the purpose of this Indian standard the coefficient of restitution (e) between two impacting bodies is defined as the relative velocity of departure divided by the relative velocity of approach.
