On March 6th HTS/DXS submitted a total of eight (8) code change proposals to the 10th edition code, amending six (6) sections of IMC 2021’s Chapter 11 on refrigeration as well as two (2) referenced standards in Chapter 15. The proposed changes would allow ASHRAE 15 to be followed exclusively in lieu of Chapter 11 of IMC 2021, and with the referenced version of the standard being updated to 2022, this would allow the State of Massachusetts to use the latest published language surrounding A2L refrigerants. Other changes also update different key sections of IMC 2021 Chapter 11, bringing the language up to IMC 2024 or ASHRAE 15 2022. HTS/DXS is looking for letters of support from the industry to BBRS for these code change proposals.
Please contact the HTS DXS Refrigerant Transition Team to learn more about the planned code change proposals, and / or to offer a letter of support.
