We derive sharp necessary conditions for weak sequential lower semicontinuity of integral functionals on Sobolev spaces, with an integrand which only depends on the gradient of a scalar field over a domain in $\{\mathbb R\}^N$. An emphasis is put on domains with infinite measure, and the integrand is allowed to assume the value $+\infty$.
