Introduction to Long Term Thermal Aging (LTTA) – UL 746B Overview


Description

The purpose of this one-day workshop is to increase your understanding of the temperature ratings assigned to a polymeric material, and how those ratings are assigned.  The workshop will provide an overview of the thermal aging project, including how and why a control material is used; how to select a control material; the type and number of samples needed for an investigation; how to select the aging temperatures for an LTTA project; and how the data is analyzed to determine the material’s temperature rating.  A series of lectures and classroom exercises have been designed to help you develop a thermal aging program for your material.    The knowledge you gain from this workshop will help facilitate the development of a thermal aging test program, helping you achieve the ratings you need as quickly as possible.
