test point [test point is a term no longer in use as test refers to mechanical or physical tests (e.g. tensile tests or
pressure tests)]
An area within a CML defined by a circle having a diameter not greater than 3 in. (75 mm) for pressure vessels. CMLs may contain multiple examination points, for example, a vessel nozzle may be a CML and have multiple examination points (e.g. an examination point in all four quadrants of the CML on the nozzle).
