6BTest, Inspection and Production Equipment

6B Test, Inspection and Production Equipment

6B004 Optical equipment as follows:

a. Equipment for measuring absolute reflectance to an “accuracy” of equal to or better than 0.1% of the reflectance value;

b. Equipment other than optical surface scattering measurement equipment, having an unobscured aperture of more than 10 cm, specially designed for the non‑contact optical measurement of a non‑planar optical surface figure (profile) to an “accuracy” of 2 nm or less (better) against the required profile.

Note: 6B004 does not apply to microscopes.

6B007 Equipment to produce, align and calibrate land‑based gravity meters with a static “accuracy” of better than 0.1 mGal.

6B008 Pulse radar cross‑section measurement systems having transmit pulse widths of 100 ns or less, and specially designed components therefor.

N.B.: SEE ALSO 6B108.

6B108 Systems, other than those specified by 6B008, specially designed for radar cross section measurement usable for ‘missiles’ and their subsystems.

In 6B108 ‘missile’ means complete rocket systems and unmanned aerial vehicle systems capable of a range exceeding 300 km.
