STP 507 - ELECTRIC FANS – Proposals generated from the February STP Meeting were processed for ballot, which closed in April. All proposals reached consensus, with several needing to be recirculated prior to publication.
In addition, a task group was formed to continue work on a proposal submitted from the CPSC to include a new thermal condition performance test for unattended fans. CPSC is leading the task group work, which is progressing to an eventual proposal for consideration by the STP and public.
STP 749 – HOUSEHOLD DISHWASHERS – The STP ballot of the proposed 11th edition concluded in May. The ballot did not reach initial consensus but received enough affirmative votes to continue to comment resolution and recirculation. The THC is reviewing the ballot comments received in preparation for recirculation, which is targeted for July.
STP 867 – ELECTROSTATIC AIR CLEANERS – An STP ballot of 22 wide-ranging proposal topics closed in May with all topics reaching consensus. Only one of the topics received a comment, which is under consideration prior to recirculation.
STP 923 – MICROWAVE COOKING APPLIANCES – A new proposal intended to address the potential risks associated with handling hot food and beverage items by young children in connection with microwave oven usage was circulated for preliminary STP review, closing in March. A number of comments were received, which are under consideration in preparation for the STP ballot. This proposal is the result of a task group that worked hard to get to this point, carefully considering information available on this topic.
STP 1017 - VACUUM CLEANERS, BLOWER CLEANERS, AND HOUSEHOLD FLOOR FINISHING MACHINES - A new revision cycle is underway.
