It is the capacity of a test specimen or artifact to withstand the action of the temperature during a certain time with the retention of the original physical properties.

It demonstrates the response of the material, in force, when submitted to deformation by linear compression.

It is the capacity of the test specimen or artifact of developing the energy absorbed during its mechanical deformation. The resilience is expressed in percentage.

It is the capacity of a material to withstand the wear through the contact against an abrasive surface. Usually, it is measured under defined conditions of load and speed. Expressed in mm³ (volume of loss).

It is a dimensional alteration of the test specimen or artifact, when submitted to the compression.

It defines the tension supported by material until the beginning of the tearing, guided in a point of the test specimen.

It determines the extension which the material extends until breaking. It is expressed as a percentage related to the measure of original length.

It is the resistance offered by the surface of a test specimen or artifact, to the penetration of an object of specified dimensions and under a certain load.

Defined as the force per unit of area required for the break of the test specimen. It is calculated by dividing the break force by section area of the test specimen. The units expressed are MPa, Kgf / cm2 or Psi ( pounds per square inch).
