Min Continuous Service Temperature

This is the minimum acceptable temperature above which mechanical properties (tensile strength, impact strength) or electrical properties (dielectric strength, linked to insulation properties) of a plastic part are significantly degrading, over the reasonable life time of the tested product.

UL 746 is the test method generally used to calculate Relative Temperature Index (RTI).

RTI is measured in °C.
