For the purposes of 2.B.4., 'isostatic presses' pressurise a closed cavity through various media (gas, liquid, solid particles, etc.) to create equal pressure in all directions within the cavity upon a workpiece or material.
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
