20、Units IEST-RP-CC036.1 1 SCOPE AND LIMITATIONS 1.1 Scope This Recommended Practice (RP) covers laboratory methods for testing the performance of a fan filter unit (FFU). The purpose of this RP is to provide customers and suppliers of FFUs the necessary test protocols for measuring and reporting perfo
21、rmance, excluding filter efficiency. These methods provide the means for direct comparison of units provided by different manufacturers, which may be of varying designs and have different operating features. The test methods identify test equipment and testing procedures necessary to measure volumet
22、ric airflow, electric power parameters (wattage, amperage, voltage, and power factor), available external static pressure, sound power levels, and filter airflow velocity uniformity. These procedures are applicable for FFUs with AC motors, with DC brushless motors, with constant airflow control, and
23、 without constant airflow control. 1.2 Limitations This RP does not provide guidance for field testing, although some of the techniques described herein can be applied to field testing. This RP does not recommend acceptance performance values or limits for FFUs. Codes and standards may be applicable
24、 to the construction and performance of FFUs. These codes and standards should be made part of the agreement between the customer and supplier. The procedures described in this RP are applicable to FFUs with filter dimensions equal to or less than 1.2 m (4 ft) in any direction. Testing for fan filte
