  In its vast majority entanglement verification is examined either in the
complete characterized or totally device independent scenario. The assumptions
imposed by these extreme cases are often either too weak or strong for real
experiments. Here we investigate this detection task for the intermediate
regime where partial knowledge of the measured observables is known,
considering cases like orthogonal, sharp or only dimension bounded
measurements. We show that for all these assumptions it is not necessary to
violate a corresponding Bell inequality in order to detect entanglement. We
derive strong detection criteria that can be directly evaluated for
experimental data and which are robust against large classes of calibration
errors. The conditions are even capable of detecting bound entanglement under
the sole assumption of dimension bounded measurements.
