Clean and bake, step 5 of 8
How clean is clean enough, and how do I prove it?
Cleanliness has no unit until a specification gives it one. This step reads the cleanliness class, the particle count and the bake that the target pressure demands.
The machine you laid, walls in their state

What already answers this
Nothing below is a copy. Each line is the surface of this site that carries the answer, and what it carries.
- /essays/clean-has-no-unit/ reads thirty specifications and shows they do not share a unit
- /academy/why-we-bake/ gives the mechanism a bake works on, and the temperature it needs
- /tools/outgassing/ serves the rate a bake actually buys, with the bake it was measured after
What are you going to do to it, and what did the base measure
The state of the walls, unbaked or baked or vacuum fired, belongs to the machine and is set at step four. What is set here is what you intend: the bake you plan to run, and the cleanliness you are going to require. Neither is read from anything. Both are written down so the dossier carries them next to the rates they sit beside.
| Material and state | Rate the base serves | Bake it was measured after | Against your bake |

What this step cannot answer, and why. Every count below is read from the corpus at build, so this block shrinks on its own the day the data grows.
- unsourced No cleanliness class is stored per material or per machine. The essay reads thirty specifications and shows they do not share a unit, which is why nothing here converts one class into another.
- unsourced No particle count data is carried. A cleanliness class can be recorded in a Bill of Vacuum as a stated requirement, and it will be marked unsourced until a document backs it.
