HB 6167.15-2014 (English Version) PDF

Scope: This part specifies the sound resistance test conditions and test methods for civil aircraft airborne equipment. The conditions specified in this section are applicable to the sound resistance functional test of the equipment during the development and production stages; they are also applicable to the sound resistance endurance test to detect structural defects during the equipment development process. This section applies to equipment that is sensitive to sound vibrations. Relevant standards should stipulate the necessity of sound resistance functional tests and sound resistance endurance tests, the use of broadband noise or harmonic noise and applicable test sound pressure levels. This section does not apply to equipment located on an aircraft where the total sound pressure level is less than 125dB.
