Evaluate the response to the cleanliness requirement
State the target class and the condition in which it is to be assessed. Explain the process, occupancy and material movement. Without those inputs, apparently similar proposals may be based on different assumptions.
Ask each company to explain the relationship between the selected enclosure, air distribution and the work taking place inside. Review the proposed acceptance scope and who is responsible for the measurements and records.
Use a capability matrix rather than an unsupported ranking. The relevant choice is the team and package that address your requirements with a clear scope, suitable technical information and practical service access.
Configuration decisions
| Decision | What to define |
|---|---|
| Class requirement | State the target and assessment condition. |
| Process assumptions | Compare occupancy, equipment and transfer inputs. |
| Technical proposal | Review the coordinated enclosure and air-system response. |
| Acceptance | Agree measurements, documents and responsibility. |
Does an ISO class label prove the proposed room will meet the target?
No. The installed and operated environment must be assessed under the agreed conditions. A component description or catalogue image is not that evidence.

Requirements depend on the intended use and project conditions. Consult the relevant current documents when defining the final specification.
