| 1 | Static Load Capacity | Minimum target: 15 kg
Load rating should cover the ironing board, garment pressure, and accidental downward force. | Apply a distributed load to the board in the fully extended and locked position. Inspect deflection, fasteners, rails, and cabinet mounting points after the test. | Signed load-test report, test fixture description, measured deflection, and product technical drawing. | 18% |
| 2 | Cycle Durability | Target: 10,000 cycles
One cycle consists of complete extension, normal operating stop, and full retraction. | Run a representative production unit under the intended load and operating speed. Record failures, abnormal noise, looseness, and dimensional change. | Cycle-test log, before-and-after measurements, failure criteria, and photographs of tested components. | 18% |
| 3 | Quality Management System | ISO 9001:2015 preferred
Certification should cover the relevant manufacturing and quality-control activities. | Check certificate validity, certification scope, issuing body, site address, and expiry date through the certification body or accreditation database. | Current ISO 9001 certificate, audit records, corrective-action procedure, and documented inspection plan. | 12% |
| 4 | OEM and ODM Capability | Complete project support
Capability should include drawings, prototypes, tooling coordination, engineering changes, and private-label packaging. | Review a sample development workflow from initial specification through pilot production and final approval. | Anonymized project timeline, sample engineering-change form, prototype photographs, and packaging specification. | 12% |
| 5 | Slide and Hinge Performance | Smooth, controlled movement
No binding, unintended closing, rail disengagement, or sharp-edge exposure during normal operation. | Inspect movement at different extension positions with the drawer installed in a representative cabinet. Check stop engagement and alignment. | Assembly drawing, rail specification, hinge specification, tolerance chart, and functional inspection checklist. | 10% |
| 6 | Corrosion Resistance | Finish suitable for indoor humidity
Metal surfaces should resist visible red rust during the agreed validation period. | Use a recognized neutral salt-spray method, such as ISO 9227, when the coating system and project risk justify laboratory corrosion testing. | Material certificate, coating specification, surface-treatment process, and laboratory test report where applicable. | 8% |
| 7 | Dimensional and Installation Accuracy | Fit within approved drawing tolerances
Typical checks include overall width, mounting-hole position, board clearance, and front-panel alignment. | Measure first-off and mass-production samples with calibrated gauges. Conduct a cabinet fit test using the buyer’s approved installation envelope. | Controlled drawings, tolerance table, gauge-calibration records, first-article inspection report, and fit-test photos. | 8% |
| 8 | Material and Component Traceability | Traceable critical parts
Rails, hinges, fasteners, board frame, cover fabric, and surface finishes should be linked to incoming inspection records. | Select production samples and trace them back to purchase orders, batch records, inspection results, and approved suppliers. | Bill of materials, lot-number system, incoming-inspection records, and nonconforming-material procedure. | 6% |
| 9 | Safety and User Ergonomics | No foreseeable pinch or cut hazards
Operation should be stable, intuitive, and accessible within the intended cabinet configuration. | Conduct a hazard review covering pinch points, sharp edges, unexpected release, hot-surface proximity, and operating clearances. | Risk assessment, edge-radius or deburring specification, user instructions, warning labels, and safety-test records. | 4% |
| 10 | Production Capacity and Delivery Control | Documented capacity plan
Supplier should demonstrate stable output, defined lead times, and contingency planning for critical components. | Compare forecast demand with line capacity, bottleneck analysis, production schedule, quality release process, and historical on-time-delivery data. | Capacity statement, production-flow chart, lead-time matrix, business-continuity plan, and anonymized delivery-performance summary. | 4% |
