The term ''classical vacuum'' as used in classical electromagnetism refers to a reference state devoid of all particles, that is, a state with zero pressure obtainable only in principle, and not in practice.
The term ''classical vacuum'' as used in classical electromagnetism and in the definition of the [[SI units]] refers to an ideal reference medium devoid of all particles, with ideal properties. These ideal properties include: independence from field strengths, direction, frequency, or polarization, and from temperature.
