Significance and Use | ||||||||||||||||||||||||
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.

1. Scope | ||||||||||||||||||||||||
1.1 This practice establishes requirements for testing and rating acoustical performance of window, door, skylight, and glazed wall systems, regardless of their method or materials of manufacture. 1.1.1 Operating force, latching force, and air leakage are integral elements of the acoustical performance of window, door, skylight, and glazed wall systems. This practice requires (when applicable) the concurrent testing of operating force, latching force, and air leakage, in addition to the sound transmission loss test. 1.2 This practice establishes the test methodology, specimen criteria, and classification rating system for purposes of determining the acoustical performance levels of window, door, skylight, and glazed wall systems only, and not through openings between such assemblies and adjacent construction. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
