# Industrial Specification: Reference Standard Station

## 1. Technical Definition
A precision measurement station within an automated calibration system that provides traceable reference standards for calibrating industrial instruments and sensors.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-1000 bar at 0.01% FS accuracy, -40°C to +85°C ambient temperature**. Failure boundary: **Pressure exceeding 1200 bar causes permanent deformation of Bourdon tube, temperature exceeding 125°C degrades piezoelectric crystal lattice structure**, Mechanism: **Yield strength of 316L stainless steel (205 MPa) exceeded at 1200 bar internal pressure, Curie temperature (350°C) proximity in PZT-5A piezoelectric sensors causes depolarization**.

### 2.1 Analytical Physics Model
Governed by the **Combined Measurement Uncertainty**:

> **Primary Equation**: $u_c = \sqrt{\sum u_i^2}$
