如题， 22.110 该如何理解？

22.110 Non-self-resetting thermal cut-outs designed to be replaced after their operation
shall open the circuit in the intended manner without short-circuiting live parts of different
potential and without causing live parts to come into contact with the enclosure.
Compliance is checked by the following test.
The appliance is operated five times, each time with a new non-self-resetting thermal cutout,
any other thermally operated control devices being short-circuited.
Each time, the thermal cut-out shall operate appropriately.
During the test, the enclosure of the appliance is connected to earth through a 3 A fuse; this
fuse shall not blow.
After this test, the supplementary heating elements shall withstand an electric strength test as
specified in 16.3.

应该是如果失效控温元件，热熔断器能即时断开，3A电流保险丝不能断开，且耐压能过。这个测试要做5次。
