a. Environmental chambers having all of the following characteristics:
1. Capable of simulating any of the following flight conditions:
a. Altitude equal to or greater than 15 km; or
b. Temperature range from below –50ºC to above 125ºC; and
2. Incorporating, or designed or modified to incorporate, a shaker unit or other vibration test equipment to produce vibration environments equal to or greater than 10 g rms, measured 'bare table', between 20 Hz and 2 kHz while imparting forces equal to or greater than 5 kN;
Technical Notes:
1. Item 15.B.4.a.2. describes systems that are capable of generating a vibration environment with a single wave (e.g. a sine wave) and systems capable of generating a broad band random vibration (i.e. power spectrum).
2. In Item 15.B.4.a.2., designed or modified means the environmental chamber provides appropriate interfaces (e.g. sealing devices) to incorporate a shaker unit or other vibration test equipment as specified in this Item.
b. Environmental chambers capable of simulating all of the following flight conditions:
1. Acoustic environments at an overall sound pressure level of 140 dB or greater (referenced to 2 x 10⁻⁵ N/m²) or with a total rated acoustic power output of 4 kW or greater; and
2. Any of the following:
a. Altitude equal to or greater than 15 km; or
b. Temperature range from below -50oC to above 125oC.
