Related Definitions: N/A
Items:
a. A controlled thermal environment within the closed cavity and possessing a chamber cavity with an inside diameter of 406 mm or more; and
b. Having any of the following:
b.1. A maximum working pressure exceeding 207 MPa;
b.2. A controlled thermal environment exceeding 1,773 K (1,500 °C); or
b.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.
