Thanks a lot for your input.How about: The measurements are within (the expected) limits".
Somehow the phrase seems better if you specify, at least a little, what the limits are:
"My daily carbohydrate consumption is not within the limits suggested by the National Institutes of Health: I love bread!"
Civil Engineering document. They are actually talking about real measurements, not as in regulations.les mesures sont correctes à la limite could mean two things:
1. the measurements (linear) are just barely/more or less accurate
2. the measures (regulations/rules) are just barely acceptable/tolerable
