Several new proposals, including updating references to component standards, a static load test for ceiling insert fans with tab mounting means, and ceiling fan blade edge requirements were circulated for STP ballot in September 2018, with ballots and comments due October 15. All topics reached consensus, with no comments. Revisions were published in November.
In addition, the task group formed to continue work on a proposal submitted from the CPSC to include a new thermal condition performance test for unattended fans, continues to make progress. CPSC is leading the task group, which is working toward development of a proposal for consideration by the STP and public.
