| 1. Architectural glazing supplier | Ask for applicable test documentation, such as EN 14449 and relevant impact-classification results. | Confirm available glass make-ups, interlayer types, colors, and finish options. | Check project-specific sizes, tolerances, edgework, and technical submittals. |
| 2. Building-envelope glazing supplier | Request evidence for the standards and building-code requirements applicable at the installation location. | Clarify whether laminated units can be supplied as part of an insulated-glass assembly. | Verify compatibility with the facade system and project performance specifications. |
| 3. Safety-glazing specialist | For U.S. projects, check relevant requirements such as ANSI Z97.1 and CPSC 16 CFR Part 1201. | Confirm the tested glass construction and intended impact-safety application. | Match certificates and test reports to the exact product configuration being quoted. |
| 4. Automotive-glazing supplier | Check the vehicle-market regulations and approval requirements relevant to the intended use. | Ask whether the supplier supports the required curved shapes, coatings, and optical specifications. | Verify tooling, sample approval, traceability, and production qualification arrangements. |
| 5. Security-glazing supplier | Request test evidence for the specified threat or performance level; do not infer performance from thickness alone. | Confirm the proposed glass and interlayer build-up for the project’s stated security objective. | Ensure test reports cover the proposed construction, dimensions, and installation conditions. |
| 6. Decorative or specialty-glass supplier | Check applicable safety-glazing standards alongside project requirements for appearance and durability. | Discuss printed, tinted, colored, or other specialty interlayer options and request samples. | Approve color, visual quality, and sample tolerances before placing a production order. |
| 7. Export-oriented glass supplier | Confirm that documentation meets the destination market’s applicable product and import requirements. | Request a written specification covering glass composition, dimensions, processing, and packing. | Agree on lead time, protective packaging, shipping terms, and responsibility for transit damage. |
