Standard Practice for Determining the Acoustical Performance of Windows, Doors, Skylight, and Glazed Wall Systems

Importancia y uso:

4.1 Air Leakage Relative to Sound Transmission—Certain frequencies are more susceptible to sound transmission through cavities or discontinuities in the test specimen; therefore, the air leakage of the test specimen is reported to allow the approving authority information relative to air tightness.

Note 1: The AAMA/WDMA/CSA 101/I.S.2/A440 document provides air leakage acceptance criteria for these products based on their performance class. Acoustical products could require a lower air leakage rate than what is required in this standard in order to achieve the desired acoustical performance.

4.2 Operating Force Relative to Sound Transmission—The use of specific sealing components to achieve a given sound rating could affect operating force of the vertical or horizontal sliding sash or panels of the assembly; therefore, operating force is reported to allow the approving authority information relative to sash or panel operating forces.

Note 2: The opening force in 28 CFR Part 36 ADA for interior hinged doors and sliding doors is limited to 5 lbf (22.2 N). The AAMA/WDMA/CSA 101/I.S.2/A440 document provides operating force acceptance criteria for products based on their performance class.

4.3 Latching Force Relative to Sound Transmission—Latching force can affect the compression of seals and the amount of damping applied to the system that in turn affects the air leakage and the acoustical performance. The use of specific sealing components and latching/locking hardware can affect the force required to close and latch the door under test. The latching force is reported to allow the approving authority information relative to sash or panel latching conditions.

Note 3: The AAMA/WDMA/CSA 101/I.S.2/A440 document states that the maximum force to latch shall be measured and reported.
