Caros especialistas em tecnologia: Gostaria de saber se existe uma definição clara para equipamentos a vácuo nos livros?

Todos os recipientes cuja pressão interna é inferior à pressão atmosférica são denominados recipientes a vácuo. Para serem considerados recipientes a vácuo de acordo com as normas GB/T150, é necessário que o nível de vácuo seja igual ou superior a 0,02 MPa
