Bulletin Dated: August 11, 2017

SUMMARY OF TOPICS

The following changes in requirements to the Standard for Polymeric Materials - Long Term Property Evaluations, UL 746B, are being proposed:

1a. PROPOSAL: Inclusion of Specialized Analysis of Polymer Variation (One-Temperature, Single-Point Thermal-Aging Program) with Technical Information and Analytical Tests to Section 20.2

1b. IMPLEMENTATION OF THE REQUIREMENTS (NOT PART OF THE ANSI PROCESS): If the changes of Topic 1a achieve consensus, in your opinion, is the scope of the changes being made to the standard not considered significant enough to require reevaluation, allowing currently certified products to maintain certification? Please provide the rationale for your voting choice.
