Division [9B106] Environmental chambers and anechoic chambers, as follows:F1

Changes not yet applied. Later legislation changes this provision in ways not yet written into the text below:

  1. a..

    Environmental chambers having all of the following:

    1. 1..

      Capable of simulating any of the following flight conditions:

      1. a..

        Altitude equal to or greater than 15 km; or

      2. b..

        Temperature range from below 223 K (– 50°C) to above 398 K (125°C); and

    2. 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.

    9B106.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 9B106.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 2B116.

    3.

    In 9B106.a.2., ‘bare table’ means a flat table, or surface, with no fixture or fittings.

  2. b..

    Environmental chambers capable of simulating the following flight conditions:

    1. 1..

      Acoustic environments at an overall sound pressure level of 140 dB or greater (referenced to 20 μPa) or with a total rated acoustic power output of 4 kW or greater; and

    2. 2..

      Altitude equal to or greater than 15 km; or

    3. 3..

      Temperature range from below 223 K (– 50°C) to above 398 K (125°C).
