New stand-on your own models utilizing R-290 created from your efficient date of this remaining rule by means of September 29, 2024, have to fulfill the requirements of both Appendix SB with the 10th edition of UL 471 or UL 60335-2-89, dependent upon which regular they have been Licensed, to comply with the use problems proven On this remaining motion.
1 commenter expressed that EPA shouldn't allow for for using R-290 in commercial ice machines with distant compressors that are not self-contained because of flammability worries.
EPA agrees generally speaking that permitting better utilization of R-290 would make it possible for for lessen local climate impacts, and so long as R-290 is made use of in accordance with the use disorders In this particular closing rule, we anticipate It'll be utilised as safely and securely as other readily available substitutes for a similar makes use of.
