method;
f. Non‑destructive inspection equipment specially designed for "composite" materials, as follows:
1. X‑ray tomography systems for three dimensional defect inspection;
2. Numerically controlled ultrasonic testing machines of which the motions for positioning transmitters or receivers are simultaneously coordinated and programmed in four or more axes to follow the three dimensional contours of the component under inspection.
g. Tow‑placement machines, of which the motions for positioning and laying tows or sheets are coordinated and programmed in two or more 'primary servo positioning' axes, specially designed for the manufacture of "composite" airframe or "missile" structures.
Technical Note:
For the purposes of 1B001.g., 'tow‑placement machines' have the ability to place one or more 'filament bands' having widths less than or equal to 25.4 mm, and to cut and restart individual 'filament band' courses during the placement process.
Technical Notes:
           1. For the purposes of 1B001., 'primary servo positioning' axes control, under computer "program" direction, the position of the end effector (i.e., head) in space relative to the work piece at the correct orientation and direction to achieve the desired process.
           2. For the purposes of 1B001., a 'filament band' is a single continuous width of fully or partially resin‑impregnated tape, tow or fibre. Fully or partially resin‑impregnated 'filament bands' include those coated with dry powder that tacks upon heating.
1. B. 002. Equipment designed to produce metal alloy powder or particulate materials and having all of the following:
a. Specially designed to avoid contamination; and
b. Specially designed for use in one of the processes specified by 1C002.c.2.
N.B.: SEE ALSO 1B102.
1. B. 003. Tools, dies, moulds or fixtures, for "superplastic forming" or "diffusion bonding" titanium, aluminium or their alloys, specially designed for the manufacture of any of the following:
a. Airframe or aerospace structures;
b. "Aircraft" or aerospace engines; or
c. Specially designed components for structures specified by 1B003.a. or for engines specified by 1B003.b.
1. B. 101. Equipment, other than that specified by 1B001, for the "production" of structural composites as follows; and specially designed components and accessories therefor:
N.B.: SEE ALSO 1B201.
Note: Components and accessories specified by 1B101 include moulds, mandrels, dies, fixtures and tooling for the preform pressing, curing, casting, sintering or bonding of composite structures, laminates, and manufactures thereof.
a. Filament winding machines or 'fibre/tow‑placement machines', of which the motions for positioning, wrapping and winding fibres can be coordinated and programmed in three or more axes, designed to fabricate composite structures or laminates from fibrous or filamentary materials, and coordinating and programming controls;
b. 'Tape‑laying machines' of which the motions for positioning and laying tape can be coordinated and programmed in two or more axes, designed for the manufacture of composite airframe and "missile" structures;
