本标准旨在建立阻尼器的统一实验室试验方法。待确定的特性包括（视情况而定）空气泄漏、压降、动态关闭和操作扭矩。当使用空气作为测试气体时，AMCA 500-D-18可作为测试阻尼器的依据。根据本标准要求进行的试验旨在证明 阻尼器的性能，并不是为了确定阻尼器的可接受水平。它不在里面 本标准的范围表明了测试的实际顺序。出于担保目的进行测试的各方可在测试前书面同意本标准的例外情况 测试。但是，只有不违反本标准任何强制性要求的试验才可进行 指定为根据本标准进行的试验。

The purpose of this standard is to establish uniform laboratory test methods for dampers. The characteristics to be determined include, as appropriate, air leakage, pressure drop, dynamic closure, and operational torque.AMCA 500-D-18 may be used as a basis for testing dampers when air is used as the test gas.A test conducted in accordance with the requirements of this standard is intended to demonstrate the performance of a damper and is not intended to determine acceptability level for a damper. It is not within the scope of this standard to indicate the actual sequence of testing.The parties to a test for guarantee purposes may agree to exceptions to this standard in writing prior to the test. However, only a test that does not violate any mandatory requirement of this standard shall be designated as a test conducted in accordance with this standard.
