This standard defines measurement procedures for estimating the risk of noise-induced hearing loss among users of noise producing equipment. It is applicable to ground vehicles, aircraft, watercraft, and mobile, transportable, and stationary equipment. The primary approach is to separ...

1.1 This practice covers the procedures for testing and measuring intergranular attack (IGA) and end grain pitting on aircraft metals and alloys caused by maintenance or production chemicals.

1.2 The standard does not purport to address all qualification testing parameters, methods, critica...

1.1 This test method covers a laboratory procedure for evaluating the water absorption potential of blanket insulation for aircraft, thereby providing a measure of potential weight increase due to water retention in an aircraft.

1.2 The water repellency (or retention) characteristics of mat...

1.1 This specification covers the composition, size, dimensions, and physical properties of glass fiber blanket thermal and acoustical insulation for use up to 700°F (370°C) in aircraft applications. For specific applications, the maximum temperature shall be agreed upon between the sup...

1.1 This practice covers the signals to be used between persons on the ground and in aircraft when two-way voice communications cannot be established during ground emergencies. Ground signals are limited to land-based ones that do not require special equipment. Flare, light, panel, and maritime s...
