2B116 (continued)
c. 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 reentry vehicle nose tips.
2B119 Balancing machines and related equipment, as follows:
NB: 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 12 500 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.
b. Indicator heads designed or modified for use with machines
specified in 2B119.a.
Technical Note:
Indicator heads are sometimes known as balancing instrumentation.
2B120 Motion simulators or rate tables having all of the following characteristics:
a. Two axes or more;
b. Designed or modified to incorporate slip rings or integrated
non-contact devices capable of transferring electrical power,
signal information, or both; and
