Popis:	In this paper, we discuss some specific features for the stress-energy tensor of vacuum nonlinear electrodynamics and based on these features we propose the inequalities which in form are close to the energy conditions widely used in general relativity and which can be interpreted as their possible nonlinear extension. The modified energy conditions were verified for the perfect fluid and real scalar field with an arbitrary coupling to the kinetic term.
