Synonym: Material property = Intensive physical property
A physical property of the material that does not depend on the amount of chemical substance and the way it is measured.
It is only defined by the material's chemical structure and/or its pressure and temperature under thermal or quasistatic equilibrium.
The material properties are usually measured at laboratories and are well tabulated within the practical range of pressure and temperature.
Any function of quantifiable material property is also a material property.
Some material properties are just numbers (like critical temperature T_c or critical pressure p_c) and some are functions of pressure and temperature (like density \rho(T, p) or viscosity \mu(T, p)).
