Laboratory Methods of Testing Louvers for Rating
1. Purpose The purpose of this standard is to establish uniform laboratory test methods for louvers. Characteristics to be determined include air leakage, air performance (pressure drop), water penetration, wind-driven rain, wind-driven sand and operational torque. It is not the purpose of this standard to establish minimum or maximum performance ratings. 2. Scope This standard may be used as a basis for testing louvers with air as the test gas. Tests conducted in accordance with the requirements of this standard are intended to demonstrate the performance of a louver and are not intended to determine the acceptability of performance. It is not in the scope of this standard to indicate actual sequences of testing or to specify minimum or maximum criteria for testing.
