| Refractive index | 1.47140 index (587.6 nm) |
| 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 Industrial Lighting Cover Glass glass processing for Borofloat Glass, identify exact grade, datums, clear aperture, mounting and sealing lands, edge profile, surface quality, coatings, quantity, inspection and packaging. |
Quality Controls for Industrial Lighting Cover Glass glass processing for Borofloat 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 Industrial Lighting Cover Glass glass processing for Borofloat 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. |
