Morphology
Brinell + number
‘Brinell’ is a proper name/eponym with no lexical clue to material properties, and ‘number’ is generic, so a B1 learner knowing both words would not predict that the phrase names a specific hardness measure. The term is technical and requires domain knowledge (Brinell hardness test) rather than compositional inference, so the meaning is not derivable from its parts.
Etymology
Brinell number is named after a man called Brinell who pressed a hard steel ball into metal to make a small dent. He measured the dent and gave it a number to show the metal's 'hardness', so today the phrase means the measured value of how hard a material is.
