31、g Fan Filter 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 re

32、porting performance, 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 me

33、asure volumetric 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

34、 control, and 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

35、be applicable 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

36、for fan filter housing vibration is an important performance parameter for FFUs used in selected arrangements and installations. This parameter is not part of the testing criteria covered in this RP. This RP does not discuss filtration efficiency or filter performance. These parameters are discussed

37、 in IEST-RP-CC001, IEST-RP-CC007, and IEST-RP-CC021. 2 REFERENCES The cited editions of the following documents are incorporated into this RP to the extent specified herein.

Usually the value is expressed as decibels (dB), referenced to 10-12 W. airflow

46、 The movement of air in a given direction with respect to a specified reference plane or other designated physical reference. The rate of airflow is expressed in terms of volume per unit time. volumetric airflow The volume of air that passes through a given surface per unit time. airflow velocity Th

47、e rate of airflow that passes through a given surface. This velocity is expressed in terms of length per unit time. airflow velocity uniformity The range of variability in the velocity of air exiting from the face of a fan filter unit (FFU), expressed as the percent relative standard deviation of th

48、e airflow velocity measurements. cleanroom A room in which the air supply, air distribution, filtration of air supply, materials of construction, pressure gradients, and operating procedures are regulated to control airborne particle concentrations to meet established air cleanliness levels, as defi
