| Rated user load | Product options covering 100 kg, 120 kg, or 150 kg, as required by the buyer | Product specification, rating label artwork, and written definition of the maximum user weight | Confirm the rating applies to the complete assembled trampoline and matches the model being quoted. |
| Load-test method | A documented test plan appropriate to the product design and intended use | Test procedure, sample identification, applied load, test duration or cycles, and results | Distinguish static load from repeated or dynamic-use testing; do not treat one as proof of the other. |
| Frame and joint strength | Construction and joints designed for the declared load and intended exercise use | Frame material and dimensions, joint details, inspection records, and relevant test results | Check for permanent deformation, cracked joints, loose connections, or other defined failure criteria after testing. |
| Mat, springs, and elastic components | Components specified for the exact model and controlled against approved requirements | Material specifications, supplier inspection records, component traceability, and applicable durability-test data | Verify component changes are reviewed and that test samples represent production materials and construction. |
| Stability and user safety | A product-specific assessment of stability, exposed edges, pinch points, and assembly risks | Risk assessment, assembly instructions, warnings, and inspection or test records | Review against the destination market’s applicable requirements; confirm instructions match the shipped configuration. |
| ISO 9001 quality management system | A current ISO 9001 certificate whose scope covers relevant manufacturing or quality activities | Certificate number, validity dates, certified site and scope, and certification-body details | Check certificate status with the issuing body or applicable accreditation directory. ISO 9001 is a QMS standard, not product certification. |
| Document and change control | Controlled specifications, drawings, inspection criteria, and revision history | Sample document register, revision records, and change-approval workflow | Confirm production and inspection use the current approved revision and that changes are communicated to the buyer. |
| Incoming and final inspection | Defined inspection checks with recorded results and handling of nonconforming items | Inspection plan, sample checklist, recent anonymized inspection records, and corrective-action procedure | Check that inspection criteria are measurable, records identify the model or lot, and defects are dispositioned. |
| Production traceability | A practical method to link finished products or lots to production and inspection records | Example batch or lot coding, production record fields, and traceability procedure | Verify a sample unit can be traced to its production lot and relevant quality records. |
| Buyer acceptance decision | Approve only after document review, sample evaluation, and agreement on the final product specification | Signed specification, approved sample record, agreed test requirements, and inspection plan | Record each requirement as verified, pending, or not met; do not infer supplier performance from a certificate alone. |
