One of the most important tests to determine a given plastic’s fitness for long-term ambient heat is the UL Standard 746B, Polymeric Materials, Long-Term Property Evaluation. As a data point, it’s shortened to Relative Thermal Index (RTI).Short Term Property Evaluations, and UL 746B, Polymeric Materials- Long Term Property Evaluations, or CSA C22.2 No. 0.17, Evaluation of Properties of Polymeric Materials. The maximum operating temperature for the products declared by the manufacturer is limited to that determined for the material during a separate, long-term investigation by a.An electronic document associated with a UL Standard for Safety or Outline of Investigation, and issued by UL to propose: A revision of a single or multiple requirement(s). A complete new edition of an existing Standard or Outline. A new Standard or Outline that has not previously been published.

In addition, long-term heat aging performance under high-temperature plastic storm (hot air oven aging), water, UV, cold, etc., are used as the material of the final evaluation.
