23、test installation methods, and pro-cedures for determining the capacity and related performancein a laboratory controlled environment of constant-volumeand variable-volume air terminal units. The standard is clas-sified as an ASHRAE standard method of measurement. Thisstandard is required for compli

It updates definitions, redefines airflow sen-sor performance testing, and adds a method to determineterminal-unit total pressure loss c
