The Compressive Strength test indicates the maximum load per unit area, expressed in MPa or Psi, that a cubic specimen is able to withstand before yielding when compressed on two opposite surfaces (rarely is the test carried out on the opposite surfaces of a cylindrical sample). The resistance to this type of stress will vary depending on whether the sample is completely dry (Dry) or fully saturated in water (Wet). Another factor that greatly influences the resistance of the material to compression is the direction of the load in relation to the bedding (rift) planes, if present.

The test provides useful information on the behavior of the stone material in relation to stresses due to structural loads (e.g. columns) or small surfaces subjected to large loads.

The standard requires a“Dry” conditioning temperature of 60 °C and a complete immersion for “Wet” conditioning of at least 48 hours. A minimum of five specimens, typically 50x50x50mm in size, are required for each of the possible conditioning-direction of the load combinations.

Co-efficient of friction is defined as “the force causing a body to slide along a plane (in the direction of sliding) to the normal force pressing the two surfaces together.” Coefficient of friction has to be measured experimentally; it cannot be measured using formulasThe ASTMC1028 test is run with the HPS (Horizontal Pull Slipmeter). The HPS measures both static and kinetic coefficient of friction. The HPS is compromised of a large pad and 50 pounds of weight that is hand pulled across tiles to measure slip resistance. .

This test method covers the determination of the resistance of listed specimens to rapidly repeated cycles of freezing and thawing in the laboratory by two different procedures:

Procedure A, Rapid Freezing and Thawing in Water, and
Procedure B, Rapid Freezing in Air and Thawing in Water. Both procedures are intended for use in determining the effects of variations in the properties of the listed specimens on the resistance of the specimens to the freezing-and-thawing cycles specified in the particular procedure. Neither procedure is intended to provide a quantitative measure of the length of service that may be expected from a specific specimen.
