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), special inspection level S-3, random sampling. Start-up & site test-ride shall be sampled on limited units. If calculated sample size exceeds total lot quantity, perform 100% inspection.
Defect Levels
1. Critical Defect (Zero Tolerance,AQL=0): Frame crack / unauthorized re-weld, tampered VIN / engine number, serious fluid leakage (fuel bike), cracked / bulged tire, complete brake / steering failure; e-bike: cracked battery-housing, damaged high-voltage harness, burnt connector, charging-port sparking. Even one defective unit → full-batch rejection, shipment prohibited.
2. Major Defect (AQL=2.5): Visible loose critical bolt, shock-absorber oil-leak, damaged wiring harness, cracked body-cover, seat damage, lamp / horn / instrument malfunction, hard start (fuel bike), missing mandatory marking / CCC label, wrong BOM configuration, missing user documents; e-bike: broken charging-port cover. Reject batch if over-limit, re-inspection after rework.
3. Minor Defect (AQL=4.0): Minor cosmetic scratch, small decal bubble, tiny plating spot, minor wooden-pallet dent. Acceptable within allowed quantity, process improvement required.
1 Inspection Workflow
1. Check wooden pallet, shipping mark and PO documents.
2. Count tool-kit, user manual, warranty card and accessories.
3. Visual inspection: body cover, fuel tank, plating parts, seat, frame weld, tire & rim; for e-bike: inspect battery housing and charging port.
4. Compliance check: VIN stamp, engine number (fuel bike), nameplate, CCC marking and BOM configuration; record VIN for each sampled unit.
5. Dimension measurement: overall length / width / height, wheel-plane offset.
6. Chassis assembly check: visual fastener check, fluid-leakage check(fuel bike), wiring harness, high-voltage components(e-bike), shock absorber, side / main stand.
7. On-site functional screening: steering test, lamp-horn-instrument test, brake check, fluid-level check(fuel bike), engine start-idle test(fuel bike), low-speed short-distance test-ride within closed plant, stand function test; e-bike charging-port inspection.
8. Verify nameplate, CCC marking and safety warnings (include high-voltage warning for e-bike) in user manual.
9. Record VIN & defects, take photos, judge accept / reject and generate inspection report.
10. Provide Container Loading Supervision service upon request.
2 Key Inspection Items
Visual & Compliance Inspection
- Frame no crack or unauthorized re-weld; VIN & engine stamp clear without grinding / tampering.
- Fuel-tank & plastic cover free of large crack / paint peeling.
- Tire no bulge or crack; rim without heavy deformation.
- CCC mark, nameplate, warning labels complete and legible.
- E-bike: Battery housing without crack; charging-port cover intact; high-voltage harness without abrasion or burn-mark.
Chassis & Assembly
- Critical fastener visual check only, no on-site torque measurement.
- No serious fuel / oil / brake-fluid leakage for fuel-powered motorcycle.
- Wiring harness intact; shock absorber without oil-leak; side-stand / main-stand support reliable.
On-site Functional Screening
1. Steering Test: Full-lock steering smooth without jamming or abnormal noise.
2. Light-Horn-Instrument Test: All lamps, horn and instrument work normally.
3. Brake Check: Brake travel reasonable, no total brake failure.
4. Fluid-Level Check (fuel-bike only): Fluid within specified range.
5. Engine Start-Idle Test (fuel-bike only): Smooth start, no violent idle shaking.
6. Low-Speed Site Test-Ride: Only inside closed factory area, wear helmet, speed ≤10 km/h, no emergency brake. No severe abnormal metallic noise, transmission works normally.
7. Side-stand / Main-stand Test: Stable supporting without jamming.
8. E-bike charging-port check: No sparking while connecting.
Marking & Manual
VIN, engine number(fuel-bike), nameplate, CCC marking shall be intact. User manual contains operation, maintenance and safety warnings; e-bike manual add high-voltage hazard warning. Mandatory translated warning for export orders.
3 Defect Classification
- Critical Defect: Frame crack / unauthorized re-weld, tampered VIN, serious fluid leakage(fuel-bike), bulged / cracked tire, steering / brake total failure; e-bike cracked battery-housing, damaged high-voltage harness, burnt connector, charging-port sparking. One found → full-batch rejection.
- Major Defect: Visible loose critical bolt, shock-absorber oil-leak, damaged harness, cracked cover / seat, lamp-horn-instrument malfunction, hard start(fuel-bike), missing CCC / mandatory marking, wrong BOM, missing documents; e-bike broken charging-port cover. Reject batch if over-limit, full rework required.
- Minor Defect: Light cosmetic scratch, small decal bubble, tiny plating spot, slight pallet dent. Allowed for release within AQL limit, continuous process improvement required.
