# Industrial Specification: Medical-Grade Polypropylene Syringe

## 1. Technical Definition
Sterile disposable syringe manufactured from medical-grade polypropylene for clinical applications.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-3.5 bar (50.8 psi) injection pressure, -0.8 to 1.2 bar (-11.6 to 17.4 psi) aspiration pressure**. Failure boundary: **Polypropylene glass transition temperature at 0°C causing brittle fracture, 4.2 bar (60.9 psi) causing barrel deformation exceeding 2% strain, 150°C causing polymer degradation**, Mechanism: **Polypropylene's glass transition temperature (Tg=0°C) induces brittle failure below freezing; yield strength (35 MPa) exceeded at 4.2 bar pressure causing permanent deformation; thermal degradation at 150°C breaks polymer chains via radical oxidation**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Polypropylene stress cracking from 0.1% benzalkonium chloride residue | 8 | Barrel wall microcrack propagation leading to catastrophic fracture at 2.1 bar pressure | Implement ISO 10993-12 extraction testing with &lt;0.01% chemical residue limit, add 2% ethylene copolymer to increase environmental stress crack resistance to 500 hours |
| Plunger seal compression set exceeding 15% after 72 hours at 40°C | 8 | Fluid leakage at 0.5 bar differential pressure, delivering 12% underdose | Replace silicone rubber with bromobutyl rubber (compression set &lt;5% at 70°C), implement 100% automated leak testing at 0.7 bar for 30 seconds |
