Gauge Glass
Gauge/sight glass
Recommended route in the application record
Gauge Glass appears in the V4.1 recommended material route for Display Cover Glass, but the exact grade and assembly conditions still require validation.
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 | Transmission, haze, reflection, color/print registration and display readability. |
| Temperature and thermal cycling | Display heat, sunlight and environmental cycling must not delaminate coating or print. |
| Chemical and cleaning exposure | Finger oils, cleaners and outdoor pollutants require durable surfaces. |
| Mechanical and mounting load | Impact, edge drop, bending and mounting adhesive stress require cover-level testing. |
| Pressure or vacuum boundary | Display Cover Glass: Define when the component forms a pressure or vacuum boundary |
| Cleaning and handling | Use display-safe, low-residue cleaning; verify oleophobic/AR coating compatibility and particle control before lamination or bonding. |
Gauge Glass for Display Cover Glass
The V4.1 application route and the selected material record are shown separately so an unsupported combination is not presented as automatically approved.
| Decision area | Application and material basis |
|---|---|
| Compatibility status | Recommended route in the application record. Gauge Glass appears in the V4.1 recommended material route for Display Cover Glass, but the exact grade and assembly conditions still require validation. |
| Application recommended route | Chemically strengthenable aluminosilicate for impact/consumer touch; low-iron or thin borosilicate for other panels. |
| Application alternatives | Chemically strengthened aluminosilicate for impact, soda-lime for cost-sensitive displays, or low-iron/optical glass when color and transmission dominate. |
| Selected material capability | Liquid-level gauges and process observation |
| Selected material limitations | Grade, thickness, surface state, wavelength and temperature conditions must not be generalized |
| Selection evidence required | Document why Gauge Glass is chosen for Display Cover Glass, including rejected alternatives and the validation method. |
| Selected material property | Published reference |
|---|---|
| Material category | Gauge/sight glass |
| Chemical resistance | Acid class 1 reported by the reviewed DIN 7081 manufacturer datasheet |
| Available forms | Oblong transparent or reflex gauge-glass plates |
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 | Cover glass, HMI panel, dead-front printed panel or EV charger interface glass. |
| Application process route | Precision cutting/edge finish, chemical strengthening when suitable, printing, coating, lamination prep and cosmetic cleaning. |
| Material-compatible processes | Precision cutting; CNC/ultrasonic machining where qualified; grinding; lapping; polishing; cleaning; inspection |
| Size and thickness | Panel-specific; thickness controls touch sensitivity, impact and weight. |
| Edge and surface zones | High cosmetic quality, safe edge, controlled flatness and accurate printed aperture. |
| Drawing release | For Display Cover Glass glass processing for Gauge Glass, identify exact grade, datums, clear aperture, mounting and sealing lands, edge profile, surface quality, coatings, quantity, inspection and packaging. |
Quality Controls for Display Cover Glass glass processing for Gauge Glass
Inspection must verify both the material-dependent characteristics and the installed application requirement.
| Risk or control | Application × material focus |
|---|---|
| Application failure modes | Edge fracture, touch sensitivity loss, print misregistration, glare, scratches and delamination. |
| Material-specific limits | Grade, thickness, surface state, wavelength and temperature conditions must not be generalized |
| Inspection method | Cosmetic inspection, dimensions/flatness, transmission/haze, print registration, touch and impact testing. |
| Standards and system validation | Customer display drawing governs; ISO 10110 may be used for optical surface/form definitions but is not a complete cover-glass qualification standard. |
| First article | For Display Cover Glass glass processing for Gauge 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. |
