Proposed Standard BSR/RESNET/ACCA 310-201x, Standard for Grading the Installation of HVAC Systems, establishes a methodology for evaluating the installation quality of Unitary HVAC systems. It establishes the procedures, tolerances, and record keeping required to evaluate elements of an HVAC System’s design and installation. The methodology is comprised of five tasks – a design review, a total duct leakage test, a Blower Fan volumetric airflow test, a Blower Fan watt draw test, and a non-invasive evaluation of refrigerant charge. The five tasks are designed to be completed in sequence and upon completion of each task, the results are evaluated for compliance with specified thresholds.
