(1,000°C), and specially designed quartz heaters therefor.
N.B.: SEE ALSO 9B106.
9. B. 007. Equipment specially designed for inspecting the integrity of rocket motors and using Non‑Destructive Test (NDT) techniques other than planar x‑ray or basic physical or chemical analysis.
9. B. 008. Transducers specially designed for the direct measurement of the wall skin friction of the test flow with a stagnation temperature exceeding 833 K (560°C).
9. B. 009. Tooling specially designed for producing gas turbine engine powder metallurgy rotor components having all of the following:

            1. Designed to operate at stress levels of 60% of Ultimate Tensile Strength (UTS) or more measured at a temperature of 873 K (600°C); and

            2. Designed to operate at 873 K (600°C) or more.

            Note: 9B009. does not specify tooling for the production of powder.
9. B. 010. Equipment specially designed for the "production" of items specified by 9A012.
9. B. 105. 'Aerodynamic test facilities' for speeds of Mach 0.9 or more, other than those specified by 9B005, usable for 'missiles' and their subsystems.
N.B.: SEE ALSO 9B005.
Note: 9B105 does not apply to wind‑tunnels for speeds of Mach 3 or less with dimension of the 'test cross section size' equal to or less than 250 mm.
Technical Notes:
1. In 9B105 'missile' means complete rocket systems or "unmanned aerial vehicle" capable of a range exceeding 300 km.
2. 'Aerodynamic test facilities' includes wind tunnels and shock tunnels for the study of airflow over objects.
3. 'Test cross section size' means the diameter of the circle, or the side of the square, or the longest side of the rectangle, or the major axis of the ellipse at the largest 'test cross section' location. 'Test cross section' is the section perpendicular to the flow direction.
9. B. 106. Environmental chambers and anechoic chambers, as follows:
a. Environmental chambers capable of simulating all the following flight conditions:
1. Having any of the following:
a. Altitude equal to or greater than 15 km; or
b. Temperature range from below 223 K (‑50oC) to above 398 K (+125oC);

9. B. 106. a. 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
