PURPOSE: To check:

(a) Protection against bulb-neck damage by the rim of the E27 lampholder.

(a) When the gauge is screwed fully home with a torque of:
- 1,0 Nm* for ceramic holders,
- 0,4 Nm* for alltoher holders,
there shall be a clearance** between the gauge and the edge of the rim of the lampholder.
