Test Method IS 1124-1974, IS 13030-1991, ASTM C 97-2009

Mohs Hardness

This test helps in determining the hardness of rock. Because granite is a??rock??composed of multiple minerals, only crystals of specific minerals within the granite would be tested for hardness.
Test Method IS 13630 (P-13) 2006

Modulus Rapture

The modulus of rupture (MOR) is the maximum surface stress in a bent beam at the instant of failure. One might expect this to be exactly the same as the strength measured in tension, but it is always larger because the volume subjected to this maximum stress is small, and the probability of a large flaw lying in the highly stressed region is also small.
Test Method IS ASTM C 99-2009, IS 1578 (P-5)1993

Test Method IS 1130-1969, IS 3316-1974, IS 14223 (P-1) 1995, IS 3622-1977, ASTM C 625, 616, 629, 503

Thermal shock test

Thermal shock is the name given to cracking as a result of rapid temperature change. Glass and ceramic objects are particularly vulnerable to this form of failure, due to their low toughness, low thermal conductivity, and high thermal expansion coefficients. However, they are used in many high temperature applications due to their high melting point.
Test Method IS 13630 (P-5)2006, EN-104, ISO 10545 (P-4)

PVC Flooring tile

PVC Flooring provides dust-free, noise absorbing, resilient, non-porous, decorative surface. It shall consist of a thoroughly blended composition of thermoplastic binder, filler and pigments.
Test Method IS 3461

Frost Resistance

Ceramic tile frost resistance is defined as the ability of ceramic tile to withstand freeze/thaw conditions with minimal effect. The frost resistance of ceramic tile is dependent on the tile''''s porosity and water absorption levels. Frost damage can occur when the variety of ceramic tile absorbs moisture through its pores, causing the water to freeze internally when temperatures drop. Since water expands when it freezes, tension is then exerted inside the body of the ceramic tile. This internal pressure may become high enough to cause cracks in the ceramic tile.??
Test Method IS 13630 (P-10), BS EN 12371

Chemical Resistance test

This test is done to determine the ability of the grade of granite used by a1-safetech to resist chemical attack.
Test Method

Thermal Conductivity

Thermal conductivity depends upon the chemical and mineralogical compositions as well as the glassy phase contained in the refractory and the application temperature. The conductivity usually changes with rise in temperature. In cases where heat transfer is required though the brick work, for example in recuperators, regenerators, muffles, etc. the refractory should have high conductivity. Low thermal conductivity is desirable for conservation of heat by providing adequate insulation.
Test Method IS 1528 (P-16)1991

Particle Size

This test helps in determining the percentile quantity of particles of known diameter within a sample. The specimen can be either passed through a set of standard sieves in its natural state, or if a significant amount of binding material is present, such as clay, then the sample can first be washed over a small aperture sieve to remove the binding material.
Test Method IS 1528 (P-14) 1974

Water absorption

Bend Test

This test helps in determining the ductility, but it cannot be considered as a quantitative means of predicting service performance in bending operations. The severity of the bend test is primarily a function of the angle of bend and inside diameter to which the specimen is bent, and of the cross-section of the specimen. These conditions are varied according to location and orientation of the test specimen and the chemical composition, tensile properties, hardness, type, and quality of the steel specified.

0.2% Proof stress / Yield stress

Yield strength is the lowest stress that produces a permanent deformation in a material. In some materials, like aluminium alloys, the point of yielding is hard to define, thus it is usually given as the stress required causing 0.2% plastic strain. This is called a 0.2% proof stress.
