Pneumatic testing supplements hydrostatic procedures for applications where leakage during gas service represents a critical concern.
| Test Type | Purpose | Acceptance Criteria |
|---|---|---|
| Hydrostatic Pressure | Body strength and seating integrity | No visible leakage at 1.5× rated pressure |
| Pneumatic Test | Gas service leakage verification | Zero bubble formation over 5-minute period |
| Dimensional Check | Assembly compatibility | Within ±0.05mm of specification |
| Torque Verification | Actuation performance | Within ±10% of published values |
| Material Verification | Chemical composition accuracy | Match material certificate data |
Beyond physical testing, the inspection department maintains real-time monitoring dashboards that track First Pass Yield rates by production line, shift, and product family. When yield rates show statistical shifts, immediate investigations trigger root cause analysis procedures designed to identify and eliminate assignable causes. This proactive quality management approach keeps defect rates low and ensures customer shipments arrive with documented conformance to specifications.
