Axial Strength of Edison Caps
The lamps shall be screwed into gauge of Table 4. After full insertion an axial force of Table 4
is applied to the central contact. See IEC62560 Figure 7.
In case axial strength of the cap does not decrease when the unmounted cap was assembled
to the finished lamp, test results on the unmounted cap can be applied.
NOTE The gauges are used to hold the lamp. Calibration is not required.
Compliance:
After this test the insulation around the central contact shall remain intact. The application of
the torque test in 9.2.1 shall not lead to impressing the bottom part of the cap into the shell.
