*The temperature resistance of the enclosure is dependent upon the installed gasket. Temperature limits can also be influenced 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.
Material Properties of Plastics
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.
