Ontario, Calif. — The IAPMO Standards Council on Nov. 4 issued a tentative interim amendment (TIA) to the 2024 edition of the Uniform Mechanical Code (UMC®).
UMC TIA 003-24 revises UMC Chapter 11, Table 1102.3 (Refrigerant Groups, Properties, and Allowable Quantities), to update the permissible refrigerant quantities pertaining to refrigerant concentration limits (RCLs) and lower flammability limits (LFLs).
The TIA was balloted through the Mechanical Technical Committee in accordance with the Regulations Governing Committee Projects to determine if there was the necessary three-fourths majority support, based on technical merit and emergency nature, to establish the recommendation for issuance.
In determining whether to issue a TIA, the Standards Council looks to the Technical Committee letter ballot for a recommendation of support. Upon a full review and consideration of all the information available to it, the Council concluded that a clear and substantial basis exists to issue UMC TIA 003-24.
