Relative Temperature Index (RTI) 相對溫度指數- Maximum service temperature for a material, where a class of critical property will not be unacceptably compromised through chemical thermal degradation, over the reasonable life of an electrical product, relative to a reference material having a confirmed, acceptable corresponding performance defined RTI.

RTI Elec - Electrical RTI, associated with critical electrical insulating properties.

RTI Mech Imp - Mechanical Impact RTI, associated with critical impact resistance, resilience and flexibility properties.

RTI Mech Str - Mechanical Strength (Mechanical without Impact) RTI, associated with critical mechanical strength where impact resistance, resilience and flexibility are not essential.
