14、d for High Velocity Wind Driven Rain Resistant Louvers 1. Purpose This standard establishes uniform laboratory test methods and minimum performance ratings for water rejection capa- bilities of louvers intended to be used in high velocity wind conditions. 2. Scope Tests conducted in accordance with
15、the requirements of this standard are intended to demonstrate the acceptabil- ity of the louver in which water infiltration must be kept to manageable amounts during a high velocity wind driven rain event. The test specimen can be approved in either an open or closed position as stated in Section 5.
16、 3. Units of Measurement 3.1 System of units SI units (The International System of Units, Le Systme International dUnits) are the primary units employed in this standard, with I-P units (inch-pound) given as the secondary reference. SI units are based on the fundamental values of the International B
17、ureau of Weights and Measures, and I-P values are based on the values of the National Institute of Standards and Technology which are, in turn, based on the values of the International Bureau. 3.2 Basic units The SI unit of length is the meter (m) or millimeter (mm); the I-P unit of length is the fo
18、ot (ft) or the inch (in.). The SI unit of mass is the kilogram (kg); the I-P unit of mass is the pound mass (lbm). The unit of time is either the minute (min) or the second (s). The SI unit of temperature is either the degree Celsius (C) or kelvin (K); The I-P unit of tem- perature is either the deg
19、ree Fahrenheit (F) or the degree Rankine (R). 3.3 Airflow rate and velocity 3.3.1 Airflow rate The SI unit of volumetric airflow rate is the cubic meter per second (m 3 /s); the I-P unit of volumetric flow rate is the cubic foot per minute (cfm). 3.3.2 Airflow velocity The SI unit of airflow velocit
20、y is the meter per second (m/s); the I-P unit of airflow velocity is the foot per minute (fpm). 3.4 Water flow rate The SI unit of liquid volume is the liter (L); the I-P unit of liq- uid volume is the gallon (gal). The SI unit of liquid flow rate is the liter per second (L/s); the I-P unit is the g
21、allon per min- ute (gpm). 3.5 Dimensionless groups Various dimensionless quantities appear in the text. Any consistent system of units may be employed to evaluate these quantities unless a numerical factor is included, in which case units must be as specified. 3.6 Physical constants The density of d
22、istilled water at saturation pressure shall be taken as 998.278 kg/m 3(62.3205 lbm/ft 3 ) at 20 C (68 F). The density of mercury at saturation pressure shall be taken at 13595.1 kg/m 3(848.714 lbm/ft 3 ) at 0 C (32F). The spe- cific weights in kg/m 3(lbm/ft 3 ) of these fluids under standard gravity
23、 in a vacuum are numerically equal to their densities at corresponding temperatures. 4. Definitions 4.1 Louver A louver is a device comprised of multiple blades. When mounted in an opening, a louver permits the flow of air but inhibits the entrance of other elements. 4.2 Specimen The test specimen i
24、s a representative sample of the louver model design and is intended to evaluate the water rejection capability of the louver model. 4.3 Performance variables 4.3.1 Water infiltration The amount of water passing through a louver during the test. 4.3.2 Rain fall simulation As calculated in Section 7.
