# Industrial Specification: Leak Testing Module

## 1. Technical Definition
A specialized component within an automated dishwasher production line that verifies the watertight integrity of assembled dishwasher units.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-3.0 bar**. Failure boundary: **Pressure sensor drift exceeding ±0.05 bar from calibrated zero point**, Mechanism: **Diaphragm fatigue in differential pressure sensors due to cyclic loading at 0.1 Hz frequency during test cycles, following Hooke's Law elastic deformation limits with Young's Modulus of 193 GPa for 316 stainless steel**.

### 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.
