Voorbeeldzinnen

1. Test benches and test stands for solid or liquid propellant rockets or rocket motors, having either of the following characteristics:
2. 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.
3. Equipment specially designed for inspecting the integrity of rocket motors using non-destructive test (NDT) techniques other than planar X-ray or basic physical or chemical analysis.
4. Vibration thrusters (shaker units), with or without associated amplifiers, capable of imparting a force equal to or greater than 50 kN, measured 'bare table', and usable in vibration test systems specified in 2B116.a.; d. Test piece support structures and electronic units designed to combine multiple shaker units in a system capable of providing an effective combined force equal to or greater than 50 kN, measured 'bare table', and usable in vibration systems specified in 2B116.a. Technical Note: In 2B116, 'bare table' means a flat table, or surface, with no fixture or fittings. 2B117 Equipment and process controls, other than those specified in 2B004, 2B005.a., 2B104 or 2B105, designed or modified for densification and pyrolysis of structural composite rocket nozzles and re-entry vehicle nose tips. 2B119 Balancing machines and related equipment, as follows: N.B.: SEE ALSO 2B219.
5. Vibration test systems employing feedback or closed loop techniques and incorporating a digital controller, capable of vibrating a system at 10 g rms or more over the entire range 20 Hz to 2000 Hz and imparting forces of 50 kN, measured 'bare table', or greater; b. Digital controllers, combined with specially designed vibration test software, with a "real time bandwidth" greater than 5 kHz designed for use with vibration test systems specified in 2B116.a.; c. Vibration thrusters (shaker units), with or without associated amplifiers, capable of imparting a force of 50 kN, measured 'bare table', or greater and usable in vibration test systems specified in 2B116.a.; d. Test piece support structures and electronic units designed to combine multiple shaker units in a system capable of providing an effective combined force of 50 kN, measured 'bare table', or greater, and usable in vibration systems specified in 2B116.a. Technical Note: In 2B116, 'bare table' means a flat table, or surface, with no fixture or fittings. 2B117 Equipment and process controls, other than those specified in 2B004, 2B005.a., 2B104 or 2B105, designed or modified for densification and pyrolysis of structural composite rocket nozzles and re-entry vehicle nose tips. 2B119 Balancing machines and related equipment, as follows: N.B.: SEE ALSO 2B219. a. Balancing machines having all the following characteristics: 1. Not capable of balancing rotors/assemblies having a mass greater than 3 kg; 2. Capable of balancing rotors/assemblies at speeds greater than 12500 rpm; 3. Capable of correcting unbalance in two planes or more; and 4. Capable of balancing to a residual specific unbalance of 0,2 g mm per kg of rotor mass; Note: 2B119.a. does not control balancing machines designed or modified for dental or other medical equipment.
