| Elevator Safety Design |
GB/T 7588.1-2020 and GB/T 7588.2-2020 |
These standards provide the principal safety rules and examination methods for the construction and installation of electric passenger and goods passenger lifts in China. They address areas such as passenger protection, doors, safety components, clearances, and control systems. |
Design calculations, approved technical drawings, conformity documentation, installation records, and inspection results. |
Ask the supplier to identify the exact standard edition used in the design and to provide a compliance matrix for the complete lift system. |
| Safety Glass Selection |
GB 15763.2-2005; GB/T 15763.3-2009 |
GB 15763.2-2005 covers tempered building glass, while GB/T 15763.3-2009 covers laminated building glass. Glass used in visible elevator enclosures, doors, or cabins should be selected according to its location, loading, breakage behavior, and applicable project requirements. |
Glass-product test report, certificate of conformity, thickness and composition records, heat-soak information where specified, and traceability markings. |
Specify whether the project requires tempered, laminated, or laminated-tempered glass rather than accepting a general description such as “safety glass.” |
| Laminated Glass Retention |
GB/T 15763.3-2009 and project specifications |
Laminated glass uses an interlayer to retain fragments after breakage. The glass make-up, interlayer type, edge protection, and environmental exposure should be evaluated together because performance depends on the complete assembly. |
Lamination test records, interlayer information, impact or breakage-performance reports, and production-batch traceability. |
For overhead, façade, or guard-panel applications, confirm the required post-breakage retention period and support conditions with the project engineer. |
| Glass Doors and Entrances |
GB/T 7588.1-2020; GB/T 7588.2-2020 |
Elevator landing doors and car doors must protect passengers from access to the shaft and moving equipment. Glass panels must not compromise door strength, guarding, visibility, or safe operation. |
Door assembly drawings, impact and strength test data where required, door-lock documentation, and commissioning records. |
Evaluate the complete door assembly, including framing, fixings, interlocks, glass retention, and clearances—not only the glass panel. |
| Mechanical Strength |
GB/T 7588.1-2020 and applicable building-glass requirements |
Glass and its supporting structure must withstand foreseeable mechanical loads, operating forces, accidental contact, and vibration without creating an unacceptable hazard. |
Structural calculations, load assumptions, fixing details, material certificates, and testing records for the assembled panel where specified. |
Require the supplier to state the design load, support span, fixing method, allowable deflection, and safety factor used for each glass element. |
| Fragmentation and Breakage |
GB 15763.2-2005 for tempered glass; GB/T 15763.3-2009 for laminated glass |
Tempered glass is designed to break into relatively small particles when fully fractured, while laminated glass is designed to retain fragments through its interlayer. The selected product must match the hazard and installation location. |
Fragmentation test results for tempered glass, laminated-glass test reports, and batch-level quality records. |
Do not substitute ordinary annealed glass where the design requires safety glazing or fragment retention. |
| Fire and Smoke Interface |
Project fire-design documents and applicable Chinese fire-protection requirements |
Glass elevator enclosures, lobbies, shafts, and adjacent building elements may be subject to fire-compartment, smoke-control, or fire-rated construction requirements. Standard tempered or laminated glass is not automatically fire-rated. |
Fire-performance classification, tested system assembly, approved fire-stopping details, and building fire-protection review documents. |
Where a fire-rated barrier is required, specify a tested fire-resistant glazing system rather than relying on the glass type alone. |
| Structural Fixings and Frames |
GB/T 7588.1-2020 plus applicable Chinese structural and building-material standards |
Frames, clamps, point fixings, gaskets, anchors, and edge supports must be compatible with the glass and designed to prevent excessive stress concentration, slippage, or glass-to-metal contact. |
Shop drawings, anchor calculations, material certificates, corrosion-protection records, and installation inspection forms. |
Review the full glass-support system and confirm tolerances, drainage, replacement access, and compatibility between metals, gaskets, and sealants. |
| Electrical and Control Safety |
GB/T 7588.1-2020 and GB/T 7588.2-2020 |
Glass construction does not replace the lift’s required safety circuits, door interlocks, emergency operation, alarm, communication, and protective control functions. |
Electrical schematics, safety-circuit test records, emergency-operation tests, alarm and communication test records, and commissioning reports. |
Confirm that decorative glass, mirrors, lighting, and transparent control panels cannot obstruct sensors, emergency controls, or required visibility. |
| Installation Quality |
GB/T 7588.1-2020; manufacturer installation instructions |
Correct alignment, edge protection, support seating, torque control, sealant application, and clearance are essential to prevent glass damage during operation. |
Installation checklist, torque records where applicable, alignment measurements, concealed-work records, and final acceptance documentation. |
Use installers experienced with both elevator systems and architectural glazing; require inspection before panels are concealed or sealed. |
| Inspection and Acceptance |
Applicable Chinese elevator inspection and supervision requirements |
Elevators must undergo the required installation, supervision, or periodic inspection procedures applicable to their classification and location. The exact process depends on the project and current regulatory requirements. |
Inspection application, supervision-inspection report where required, acceptance records, registration documentation, and maintenance contract. |
Confirm in advance which local authority or inspection body will accept the installation and which documents must be supplied by the manufacturer and installer. |
| Maintenance and Replacement |
Elevator maintenance requirements and supplier instructions |
Transparent panels, door glazing, seals, fixings, and protective finishes require routine inspection for cracks, chips, delamination, corrosion, looseness, and water or cleaning-chemical damage. |
Maintenance schedule, spare-glass identification, replacement procedure, cleaning instructions, inspection logs, and service records. |
Specify replacement lead time, panel identification, approved cleaning chemicals, and procedures for taking a damaged glass panel out of service. |
| Supplier Qualification |
Chinese elevator regulatory and quality-control framework |
A qualified project supplier should be able to demonstrate appropriate manufacturing capability, documented quality control, traceable materials, competent installation, and cooperation with inspection and acceptance procedures. |
Business and production qualifications, quality-management records, product certificates, test reports, project references without relying on brand claims, and after-sales procedures. |
Compare suppliers by documented compliance, engineering support, testing evidence, delivery controls, warranty terms, and local service capability—not by appearance alone. |
