# Industrial Specification: Inspection / Access Door

## 1. Technical Definition
A removable or hinged panel on a discharge chute that provides access for inspection, maintenance, and cleaning of the chute interior.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-2.5 bar differential pressure**. Failure boundary: **3.8 bar differential pressure causing permanent seal deformation**, Mechanism: **Exceeding the yield strength of 304 stainless steel (205 MPa) at hinge mounting points under differential pressure loading**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Corrosion-induced material thinning at hinge pin interface | 8 | Hinge pin seizure preventing door operation | 316L stainless steel construction with 0.5 mm sacrificial corrosion allowance |
| Repeated impact loading during maintenance access cycles | 8 | Latch mechanism fatigue fracture at stress concentration points | Forged steel latch components with shot peening to induce 400 MPa compressive surface stress |

## 3. Key Technical Parameters
