# Industrial Specification: Sealing Door

## 1. Technical Definition
A specialized door designed to create an airtight seal for the Sterilization Zone, preventing contamination and maintaining controlled environmental conditions.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.0 bar differential pressure**. Failure boundary: **3.5 bar differential pressure causing gasket extrusion beyond 15% compression**, Mechanism: **Gasket material (EPDM rubber) undergoes permanent deformation at 3.5 bar due to exceeding its 25 MPa compressive yield strength, breaking the molecular cross-links in the polymer matrix**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| P | Internal Pressure | Engineering Constant |
| D | Diameter | Engineering Constant |
| t | Wall Thickness | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Cyclic pressure differential exceeding 1.8 bar at 0.5 Hz frequency | 8 | Gasket fatigue cracking at hinge-side compression point | Install pressure-equalization valves with 1.5 bar cracking pressure and 0.3 second response time |
| Ambient temperature exceeding 85°C for &gt;30 minutes | 8 | Gasket thermal degradation reducing sealing force below 150 N/m | Integrate Peltier cooling plates maintaining gasket interface at 40±5°C |
