membrane tool finishing'; or
5. 'Fluid jet finishing'.
Technical Notes:
For the purposes of 2B002:
1. 'MRF' is a material removal process using an abrasive magnetic fluid whose viscosity is controlled by a magnetic field.
2. 'ERF' is a removal process using an abrasive fluid whose viscosity is controlled by an electric field.
3. 'Energetic particle beam finishing' uses Reactive Atom Plasmas (RAP) or ion-beams to selectively remove material.
4. 'Inflatable membrane tool finishing' is a process that uses a pressurized membrane that deforms to contact the workpiece over a small area.
5. 'Fluid jet finishing' makes use of a fluid stream for material removal.
2. B. 003. "Numerically controlled" machine tools, specially designed for the shaving, finishing, grinding or honing of hardened (Rc = 40 or more) spur, helical and double‑helical gears having all of the following:
a. A pitch diameter exceeding 1,250 mm;
b. A face width of 15% of pitch diameter or larger; and
c. A finished quality of AGMA 14 or better (equivalent to ISO 1328 class 3).
2. B. 004. Hot "isostatic presses" having all of the following, and specially designed components and accessories therefor:
N.B.: SEE ALSO 2B104 AND 2B204.
a. A controlled thermal environment within the closed cavity and a chamber cavity with an inside diameter of 406 mm or more; and
b. Having any of the following:
1. A maximum working pressure exceeding 207 MPa;
2. A controlled thermal environment exceeding 1,773 K (1,500°C); or
3. A facility for hydrocarbon impregnation and removal of resultant gaseous degradation products.
Technical Note:
For the purposes of 2B004., the inside chamber dimension is that of the chamber in which both the working temperature and the working pressure are achieved and does not include fixtures. That dimension will be the smaller of either the inside diameter of the pressure chamber or the inside diameter of the insulated furnace chamber, depending on which of the two chambers is located inside the other.
N.B.: For specially designed dies, moulds and tooling see 1B003, 9B009 and the Munitions List.
2. B. 005. Equipment specially designed for the deposition, processing and in‑process control of inorganic overlays, coatings and surface modifications, as follows, for substrates, by processes shown in the Table and associated Notes following 2E301, and specially designed automated handling, positioning, manipulation and control components therefor:
2. B. 005. a. Chemical vapour deposition (CVD) production equipment having all of the following:
N.B.: SEE ALSO 2B105.
1. A process modified for one of the following:
a. Pulsating CVD;
b. Controlled nucleation thermal deposition (CNTD); or
c. Plasma enhanced or plasma assisted CVD; and
2. Having any of the following:
a. Incorporating high vacuum (equal to or less than 0.01 Pa) rotating
