Joint NIST Underwriters Laboratory meeting


This meeting has two distinct objectives: 

  • First, work on the current issues surrounding changes to the existing UL 746 process including the thermogravimetric analysis (TGA) round robin, component sensitivity and interactions, and Cloud Relative Thermal Index (RTI). These efforts will be captured in a workshop summary or white paper.

  • Second, outline and focus future research efforts around expanding the concept of RTI to include exposures which are often encountered but not included in the current process such as ultraviolet light, moisture and mechanical strain. This would enable an "UL Outside" type of rating. While the implementation for such a rating will be a few years off, current vigorous research efforts are laying the technical foundation for the future test methods, policies and procedures. These existing and proposed research activities will be presented as well as opportunities to participate in the industrial oversight consortium.

The meeting will be held at the National Institute of Standards and Technology in Gaithersburg, MD, near Washington DC. The two and half day meeting will take place on September 30 and end by noon on October 2nd. 

This meeting will have five sessions featuring a mix of speakers, panel discussions and break-out sessions. 

The five session topics will be:  

  • Aging test methods and the round robin testing for UL 746 (TGA).

  • How do ingredients alter performance and interact with each other?
    • How does this impact UL 746A Tables 9.1?
    • Is a new Table 9.3 needed to detail the available test methods for different ingredient modifications? Developments in the RTI cloud
  • Developments in the RTI Banding/Cloud
  • White paper development
  • More than thermal conditions: the bright, wet, strained future of RTI.
