A scientific claim is a generalization based on a reported statistically significant effect. The reproducibility of that claim is its scientific meaning. Anything not explicitly mentioned in a scientific claim as a limitation of the claim's scope means that it implicitly generalizes over these unmentioned aspects. Hence, so-called “conceptual” replications that differ in these unmentioned aspects from the original study are legitimate, and necessary to test the generalization implied by the original study's claim.
