# Industrial Specification: Safety Interlock &amp; Viewport

## 1. Technical Definition
A safety-critical component of a UV curing chamber that combines an interlock mechanism with a protective viewing window.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-1.5 bar differential pressure across viewport**. Failure boundary: **2.0 bar differential pressure causing viewport fracture at 3.0 mm thickness**, Mechanism: **Brittle fracture of borosilicate glass (Young's modulus 64 GPa, fracture toughness 0.75 MPa·m¹/²) exceeding tensile strength of 35 MPa under pressure differential**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| UV radiation at 365 nm wavelength causing photodegradation of polycarbonate interlock seals | 8 | Seal hardening and compression set exceeding 15% leading to interlock bypass | PTFE-coated silicone seals with UV stabilizers (HALS additives at 0.5% concentration) |
| Thermal cycling between 20°C and 80°C at 5 cycles/hour | 8 | Differential thermal expansion (CTE mismatch: glass 3.25×10⁻⁶/°C vs aluminum frame 23.1×10⁻⁶/°C) causing seal detachment | Elastomeric gasket with 300% elongation capacity and thermal conductivity of 0.25 W/m·K |

- **Caution**: 
- **Caution**: 

### Q: What materials are used in the safety interlock viewport?
**A**: The viewport uses UV-blocking polycarbonate or safety glass with UV filter coating, housed in a durable stainless steel frame for maximum protection and longevity.

### Q: How does the interlock mechanism enhance safety?
**A**: The interlock sensor prevents the UV curing chamber from operating when the viewport is open or compromised, ensuring operators cannot be exposed to harmful UV radiation during maintenance or inspection.

### Q: What industries commonly use this safety component?
**A**: Primarily used in machinery and equipment manufacturing for UV curing applications in printing, coating, electronics assembly, and composite material production where operator safety is critical.
