Hot ‘isostatic presses’ having all of the following, and specially designed components and accessories therefor: (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.

“Isostatic presses”, other than those specified in 2B004 or 2B104, and related equipment, as follows: a.  “Isostatic presses” having both of the following characteristics: 1.  Capable of achieving a maximum working pressure of 69 MPa or greater; and 2.  A chamber cavity with an inside diameter in excess of 152 mm; b.  Dies, moulds and controls, specially designed for “isostatic presses” specified in 2B204.a. Technical Note: In 2B204 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.

Batch centrifuges with a rotor capacity of 4 litres or greater, usable with biological materials.
