mandatory for product testing starting 17 July 2023. Manufacturers will be required to use the 
amended test procedure at appendix C1 until the compliance date of any final rule establishing 
amended energy conservation standards based on the newly established test procedure at appendix 
C2. At such time, manufacturers will be required to begin using the newly established test procedure
