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 | Specify visible transmission, diffusion or beam pattern, color neutrality, glare and coating/texture. |
| Temperature and thermal cycling | Model LED/lamp hot spots, ambient cycling and cold-water or weather shock. |
| Chemical and cleaning exposure | Outdoor pollutants, salt, cleaning agents and sealants must not cloud or attack the glass/coating. |
| Mechanical and mounting load | Impact, fixture retention and gasket load must be tested with the complete luminaire. |
| Pressure or vacuum boundary | Industrial Lighting Glass: Define when the component forms a pressure or vacuum boundary |
| Cleaning and handling | Remove dust and fingerprints that create hot spots or light scatter; verify detergent compatibility with coatings, printing and tempered edges. |
Optical Glass for Lighting 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 | 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. |
| Application recommended route | Low-expansion borosilicate for high-intensity/thermal-shock duty; low-iron/float or patterned glass where heat is moderate. |
| Application alternatives | BOROFLOAT or other borosilicate for heat-resistant covers, low-iron glass for visible efficiency, and glass-ceramic for higher heater temperature. |
| Selected material capability | Optical, thermal, chemical or mechanical glass components within the cited grade limits |
| Selected material limitations | Grade, thickness, surface state, wavelength and temperature conditions must not be generalized |
| Selection evidence required | Document why Optical Glass is chosen for Lighting Glass, including rejected alternatives and the validation method. |
| Selected material property | Published reference |
|---|---|
| Material category | Optical glass |
| Refractive index | 1.50847 index (587.6 nm); 1.51045 index (546.1 nm); 1.48062 index (Spectral table); 1.49233 index (Spectral table); 1.49813 index (Spectral table); 1.50129 index (Spectral table); 1.50671 index (Spectral table); 1.51423 index (Spectral table) |
| Available forms | Sheet, plate, disc, window, tube, rod or blank where the named grade is supplied in that form |
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 | Flat disc/cover, Fresnel or prismatic lens, domed cover, diffuser or protective plate. |
| Application process route | Circle/profile cutting, hole/slot cutting, edge grinding/chamfering, lens pressing where applicable, strengthening and cleaning. |
| Material-compatible processes | Precision cutting; CNC/ultrasonic machining where qualified; grinding; lapping; polishing; cleaning; inspection |
| Size and thickness | A documented BOROFLOAT lighting disc is 9 inch diameter by 0.109 inch thick; this is an example, not a standard range. |
| Edge and surface zones | Chip-free edges, controlled lens/prism surface and no defects that disturb beam pattern. |
| Drawing release | For Lighting Glass 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 Lighting Glass 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 | Thermal-shock cracking, low transmission, glare, lens-pattern error, edge chips and seal leakage. |
| Material-specific limits | Grade, thickness, surface state, wavelength and temperature conditions must not be generalized |
| Inspection method | Transmission/photometry, dimensional and edge inspection, thermal-cycle/thermal-shock and fixture impact/ingress tests. |
| Standards and system validation | IEC 60598-1:2024 applies to the luminaire system; glass material and dimensional acceptance remains drawing- and supplier-specification based. |
| First article | For Lighting Glass 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. |
