| Product Structure | Drawer-mounted ironing board design, hinge layout, locking mechanism, clearance, and installation compatibility. | Board opens and closes smoothly without binding; the locking mechanism holds the board securely in both stored and working positions. | Review engineering drawings, inspect a production sample, and test the product in the intended cabinet or drawer structure. | 15% |
| Load Capacity | Static load resistance of the board, rails, hinges, mounting brackets, and fixing points. | The supplier should define a rated load and demonstrate a safety margin through documented testing. A minimum 20% safety margin above the stated working load is a practical purchasing benchmark. | Request test records and conduct a witnessed load test using calibrated weights. | 12% |
| Dimensional Accuracy | Flatness, board thickness, mounting-hole position, drawer width, and overall retracted dimensions. | Critical dimensions should be controlled according to approved drawings. For metal or machined mounting parts, a general tolerance around ±0.5 mm is a useful starting point unless the drawing specifies otherwise. | Use calipers, gauges, and a dimensional inspection report based on the approved technical drawing. | 12% |
| Material Specification | Steel or aluminum grade, rail material, fastener quality, board core, cover fabric, and heat-resistant components. | All materials should be listed in the bill of materials and traceable to supplier declarations or purchase records. Materials must be suitable for repeated household heat and mechanical use. | Check the bill of materials, material certificates, incoming inspection records, and random sample composition where required. | 10% |
| Surface Treatment | Powder coating, plating, paint adhesion, corrosion resistance, edge finishing, and visible-surface consistency. | No sharp edges, exposed rust, peeling, blistering, or visible coating defects. The required corrosion test duration should be agreed according to the destination market and product specification. | Perform visual inspection, coating-thickness checks where applicable, adhesion testing, and independent corrosion testing for higher-risk applications. | 10% |
| Cycle Durability | Repeated opening, unfolding, folding, closing, and locking of the complete assembly. | A supplier should provide a documented cycle target suitable for the intended use. A buyer-defined test of at least 5,000 operating cycles is a reasonable baseline for screening household products. | Review durability test records and conduct sample testing for noise, looseness, deformation, and locking performance after cycling. | 15% |
| Safety and User Protection | Finger-pinch risks, sharp corners, unexpected board movement, heat exposure, fabric flammability, and fastener security. | No accessible sharp edges or unstable movement during normal use. Safety warnings, installation instructions, and heat-related precautions should be supplied where applicable. | Complete a product safety checklist, review risk-analysis documents, and test the assembled product under normal and foreseeable misuse conditions. | 10% |
| Quality Management | Incoming inspection, in-process controls, final inspection, nonconformance handling, and corrective-action procedures. | The factory should maintain documented inspection plans, inspection equipment, batch records, and corrective-action reports. An ISO 9001-certified system is useful but should not replace product-level verification. | Conduct a factory audit and review inspection records from recent production batches. | 10% |
| Production Capability | In-house or controlled processes for stamping, bending, welding, coating, assembly, packaging, and tooling maintenance. | The supplier should identify process ownership, available equipment, production capacity, lead-time assumptions, and contingency plans for critical components. | Review the process flow, equipment list, capacity plan, workforce, subcontractor controls, and sample production records. | 8% |
| Compliance and Documentation | Technical file, user instructions, packaging specifications, restricted-substance requirements, and destination-market compliance. | Documents should match the final product configuration, revision level, and destination-market requirements. Regulatory claims must be supported by valid test reports. | Check certificates, declarations, test reports, artwork, manuals, and revision-controlled technical documents. | 5% |
| Packaging and Logistics | Protection against scratches, deformation, moisture, missing hardware, and transit movement. | Packaging should protect moving parts and finished surfaces, include installation hardware, and pass an agreed transport simulation or drop-test standard when required. | Inspect packaging samples, conduct distribution testing, and verify carton labels, packing lists, and shipment traceability. | 3% |
