Issued by: Guangdong China Inspection and Testing Co., Ltd, holding authoritative qualifications including CMA, CNAS, ISO/IEC17020, ISO9001, providing integrated service of on-site inspection, sample sealing & laboratory testing. |
Sampling Rules
Follow GB/T2828.1-2012 (equivalent to ANSI/ASQ Z1.4), General Inspection Level-II, random sampling. Destructive tests such as tension, drop-test sampled as required. If calculated sample size exceeds total lot quantity, perform 100% inspection.
Defect Levels
1. Critical Defect (Zero Tolerance,AQL=0): Sharp burr / splinter causing cut risk, moth-eaten hole, visible mildew, penetrating crack. Even one defective unit → full-batch rejection, shipment prohibited.
2. Major Defect (AQL=2.5): Delamination / de-bond of joint, loose handle / grip, severe out-of-spec moisture content, crack after drop-test, pungent glue / mildew smell, severe warpage, missing mandatory safety warning. Reject batch if over-limit, re-inspection after rework.
3. Minor Defect (AQL=4.0): Minor natural color difference, small sound live knot, slight glue residue, minor carton dent. Acceptable within allowed quantity, process improvement required.
1 Inspection Workflow
1. Check outer carton, shipping mark and PO documents, check desiccant inside carton.
2. Inspect color box, inner protective packing, manual and warning label.
3. Count complete set of accessories.
4. Visual inspection: burr, crack, mildew, insect damage, bonding joint, coating & metal fitting.
5. Dimension measurement: length, width, thickness, diagonal, hole dimension.
6. Assembly check: bonding condition, handle firmness, board warpage.
7. On-site functional screening: moisture-content spot-check, tension test, burr-feeling check, drop-test spot-check, odor sensory test, warpage measurement.
8. Verify marking and user manual safety warnings.
9. Count defects, take photos, judge accept / reject and generate inspection report.
10. Provide Container Loading Supervision service upon request.
2 Key Inspection Items
Visual Inspection
- No sharp burr / splinter; no penetrating crack, mildew, moth-eaten hole.
- Bonded joint: no delamination or open gap over 0.1 mm.
- Coating: no peeling or sticky surface. Minor natural color difference is acceptable.
- Metal fitting: no sharp edge, no loose assembly.
Dimension & Assembly
Measure length, width, thickness, diagonal, hole size against approved sample. Check joint bonding, handle firmness and board warpage.
On-site Functional Screening
1. Moisture-content spot-check: portable moisture-meter, reference range 8-12%. For screening purpose only.
2. Handle / joint tension test: no crack or separation under moderate pulling force.
3. Burr check: run finger over all edges, no sharp splinter.
4. Drop spot-check: 30 cm drop onto hard floor; no penetrating crack or de-bonding.
5. Odor test: no pungent glue smell or mildew odor.
6. Warpage check: lay product on flat platform, excessive warpage = Major defect.
Marking & Manual
Mark material type, origin and brand. User manual must include warnings: do not soak for long time, wipe-dry after use, not suitable for dishwasher. Mandatory translated warning for export orders.
3 Defect Classification
- Critical Defect: Sharp burr / splinter, mildew / moth-eaten hole, penetrating crack. One found → full-batch rejection.
- Major Defect: Bond delamination, loose handle, excessive moisture, crack after drop-test, bad odor, severe warpage, missing safety warning. Reject batch if over-limit, full rework required.
- Minor Defect: Natural slight color difference, small live wood-knot, slight glue residue, minor carton dent. Allowed for release within AQL limit, continuous process improvement required.
