PERFORMANCE DATA
CEILING DIFFUSERS
PRODUCTS TESTING >>
The following tables iclude the results of tests conducted on three square celling diffusers. The test results include
noise criteria (NC) static pressure versus airflow, throw and Ak. The diffusers were selected and supplied by Beta
in 1991. The extrapolations and interpolations were made to cover a full range of sizes and parameters according to
ETL Testing Laboratories Inc. who made the tests.
TEST METHOD >>
The air diffusers were tested in accordance with the Air Diffusion Council test code for grilles, registers and
diffusers No. ADC 1062:GRD-84. The test was conducted in ETL Testing Laboratories Inc.
The diffusers were installed in the ADC facility and supplied with measured volume of air. The static pressure was
measured (1-1.5) duct diameter upstream of the diffuser inlet.
Acoustical data was obtained employing a Bruel and Kjaer digital frequency analyzer and analyzed by computer.
Sound power levels were plotted on a graph of Noise Criteria Curves which are in the ADC codes.

PERFORMANCE DATA
CEILING DIFFUSERS
PRODUCTS TESTING >>
The following tables iclude the results of tests conducted on three square celling diffusers. The test results include
noise criteria (NC) static pressure versus airflow, throw and Ak. The diffusers were selected and supplied by Beta
in 1991. The extrapolations and interpolations were made to cover a full range of sizes and parameters according to
ETL Testing Laboratories Inc. who made the tests.
TEST METHOD >>
The air diffusers were tested in accordance with the Air Diffusion Council test code for grilles, registers and
diffusers No. ADC 1062:GRD-84. The test was conducted in ETL Testing Laboratories Inc.
The diffusers were installed in the ADC facility and supplied with measured volume of air. The static pressure was
measured (1-1.5) duct diameter upstream of the diffuser inlet.
Acoustical data was obtained employing a Bruel and Kjaer digital frequency analyzer and analyzed by computer.
Sound power levels were plotted on a graph of Noise Criteria Curves which are in the ADC codes.
