Description: Given an inclusion B ⊂ F of (graded) local nets, we analyse the structure of the corresponding inclusion of scaling limit nets B₀ ⊂ F₀, giving conditions, fulfilled in free field theory, under which the unicity of the scaling limit of F implies that of the scaling limit of B. As a byproduct, we compute explicitly the (unique) scaling limit of the fixpoint nets of scalar free field theories. In the particular case of an inclusion A ⊂ B of local nets with the same canonical field net F, we find sufficient conditions which entail the equality of the canonical field nets of A₀ and B₀₋
