¹⁾ The ability of the enclosure to maintain their shape when subject to heat depends on a seal being inserted. The temperature resistance can still be affected by mechanical stress.

The above data are for guidance only. It has been determined using standardized test pieces and can vary within normal tolerances.
The combustibility classification refers to the material and deviations are possible in finished parts if these have a different material strength.
