Conditional route requiring engineering review
Optical Glass is not explicitly identified as a recommended or alternative route in the assigned V4.1 application record. Treat it as conditional until an engineering review documents the selection basis.
Drawing and system validation
The material name does not certify the installed equipment. Grade, thickness, edge, surface, coating, mounting and service-condition validation remain project-specific.
Application Conditions That Control Material Selection
Optical, thermal, chemical, mechanical, pressure, sealing and cleaning requirements must be defined before this material route is accepted.
| Service condition | What to define |
|---|---|
| Optical or viewing requirement | Viewing, meniscus or optical measurement needs determine clarity, path and distortion. |
| Temperature and thermal cycling | Fluid temperature, CIP/SIP cycle and thermal shock must be defined. |
| Chemical and cleaning exposure | Fluid, additives and cleaning chemistry must be compatible with glass and seals. |
| Mechanical and mounting load | Pressure pulsation, fitting load, vibration and water hammer require assembly validation. |
| Pressure or vacuum boundary | Fluid Control Equipment Glass: Define when the component forms a pressure or vacuum boundary |
| Cleaning and handling | Flush and verify internal passages; control particles, films and extractables that affect valves, sensors or analytical readings. |

Drawing, Processing and Assembly Definition
Phase 6I does not import generic process capability numbers. Manufacturing and acceptance remain tied to the exact grade, geometry, quantity and drawing.
| Route item | Project-specific requirement |
|---|---|
| Typical component forms | Tube, flow cell, sight glass, gauge tube, rotameter or pump/valve observation window. |
| Application process route | Tube cutting/calibration, drilling/ports, edge finishing, optical polishing where measured, cleaning and leak testing. |
| Material-compatible processes | Precision cutting; CNC/ultrasonic machining where qualified; grinding; lapping; polishing; cleaning; inspection |
| Size and thickness | DURAN tubes 3–465 mm OD are a supply reference; gauge variants publish 90–600 psi by size/end finish. |
| Edge and surface zones | Smooth flow/contact surfaces, chip-free ports and square tube ends for seals. |
| Drawing release | For Process Control Window glass processing for Optical Glass, identify exact grade, datums, clear aperture, mounting and sealing lands, edge profile, surface quality, coatings, quantity, inspection and packaging. |
Quality Controls for Process Control Window glass processing for Optical Glass
Inspection must verify both the material-dependent characteristics and the installed application requirement.
| Risk or control | Application × material focus |
|---|---|
| Application failure modes | Leakage, bubble retention, tube-end chips, chemical attack, pressure misuse and fitting stress. |
| Material-specific limits | Grade, thickness, surface state, wavelength and temperature conditions must not be generalized |
| Inspection method | Dimensions/ovality, port inspection, surface cleanliness, pressure/leak and flow-function test. |
| Standards and system validation | ISO 20485:2017 may be used for tracer-gas leak testing; pressure and fluid compatibility remain assembly-specific. |
| First article | For Process Control Window glass processing for Optical Glass, validate fit, optical or viewing performance, mounting, cleaning and the most critical service condition before batch release. |
| Traceability and packaging | State grade certificate, lot, inspection report, coating side, cleanliness, edge protection and packaging requirements. |
