Relative thermal endurance index

The Relative thermal index (RTI) is a characteristic parameter related to the ability of plastic materials to resist thermal degradation. The RTI is part of the longterm thermal aging program (LTTA) described in the UL 746B standard from UL. During the process of the UL 746B program, the degradation in hot air of certain properties of the …
