# Industrial Specification: Atmosphere Control Enclosure (optional)

## 1. Technical Definition
Optional enclosure that creates and maintains a controlled atmosphere environment within the Final Sealing Station

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.8-1.2 bar absolute pressure, 20-25°C temperature, &lt;100 ppm oxygen concentration**. Failure boundary: **Pressure differential &gt;0.5 bar across enclosure walls, temperature deviation &gt;±5°C from setpoint, oxygen concentration &gt;500 ppm**, Mechanism: **Excessive pressure differential causes structural deformation via von Mises yield criterion (σ_vm &gt; 250 MPa for 316L stainless steel), temperature gradients induce thermal stress exceeding material's thermal fatigue limit (ΔT &gt; 30°C), oxygen ingress initiates galvanic corrosion at sealing interfaces**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
