Circular plan surface diameter of 30mm , IEC 62368-1 Annex T Mechanical strength tests

T.4 Steady force test, 100 N
The test is conducted by subjecting the external enclosure to a steady force of 100 N ± 10 N over a circular plane surface 30 mm in diameter for a short time duration of approximately 5 s, applied in turn to the top, bottom, and sides.

T.5 Steady force test, 250 N
The test is conducted by subjecting the external enclosures to a steady force of 250 N ± 10 N over a circular plane surface 30 mm in diameter for a short time period of approximately 5 s, applied in turn to the top, bottom and sides.

The plane diameter is 30mm,tail M6 thread can be connected with the push tension meter.
