The IAPMO Standards Council on Nov. 21 issued four tentative interim amendments revising the 2018 edition of the Uniform Mechanical Code.
TIA UMC 001-18, 002-18, 003-18, and 004-18 revise UMC Chapter 2, Chapter 11, and Appendix E to update ASHRAE extracts to the latest editions of the ASHRAE 15, ASHRAE 34, ASHRAE 62.2, and ASHRAE 90.1 standards.
These TIAs were balloted through the UMC Technical Committee in accordance with the Regulations Governing Committee Projects to determine if there existed the necessary three-fourths majority support on technical merit and emergency nature to establish the recommendation for issuance.
In determining whether or not 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 TIA UMC 001-18, 002-18, 003-18 and 004-18.
TIAs are proposals based on the determination of an emergency nature requiring prompt action to amend code that contains an error or omission that was overlooked during the regular code development process, contains a conflict within the document or with another IAPMO document, or to correct a hazard, promote an advancement in safeguarding the public or provide an opportunity to correct an adverse impact on a product or method of installation.
