Core On-Site Inspection Items

Our inspectors perform on-site Quality Control based on AQL sampling, ISO 2859-1, and ANSI/ASQ Z1.4 standards. Key inspection items include:

1. On-Site Safety Testing (Core)

Lighting products directly affect user safety. Our inspectors use portable safety testing instruments at the factory, without sending samples to a laboratory. Tests include:

• High-Voltage Withstand Test: Applies specified high voltage between live parts and accessible metal parts for 1 minute. For Class I luminaires, test voltage is generally 2U + 1000V; for Class II luminaires, 4U + 2000V. Breakdown, flashover, or excessive leakage current is judged as a failure.

• Grounding Continuity Test: For Class I luminaires with protective grounding, applies specified current and measures resistance between the grounding terminal and accessible metal parts. The limit is generally ≤0.1Ω, with some buyers requiring ≤0.05Ω.

• Leakage Current Test: Measures leakage current at 1.06 times rated voltage under normal operation. Class I luminaires are generally limited to 0.75mA, Class II luminaires to 0.25mA, and handheld or portable luminaires to stricter limits.

• Power & Current Check: Measures actual input power and current at rated voltage. Actual power consumption should not exceed 120% of rated power, and power factor should generally be no less than 0.9, subject to product standard requirements.

2. Appearance & Workmanship

• Lamp body appearance: scratches, cracks, shrinkage, deformation, color deviation, stains, bubbles, and flow marks.

• Lamp shade inspection: glass shades checked for cracks, bubbles, chipping, and impurities; acrylic/PC shades checked for scratches, bubbles, deformation, and color deviation.

• Edges and corners: all accessible edges must be smooth, with no sharp burrs or chipping; heat dissipation holes and mounting brackets must be free from sharp edges.

• Lamp holders and interfaces: E27, E14, GU10, and other specifications must match order requirements; terminals must be secure and free from distortion, rust, or oxidation.

• Power cord and plug: no damage, indentation, or twisting; plug type must comply with the target market; strain relief must be intact. External power cords should be no less than 1.5m and pass pull tests without displacement or detachment.

• Nameplate and markings: model, rated voltage/power, manufacturer, and warnings must be clear, complete, and correct.

3. Function & Performance

• Switch, dimming, color temperature switching, and remote-control functions.

• Lighting-up check: no dead LEDs, dark LEDs, flickering, or color deviation.

• Color temperature and brightness visual comparison against approved samples.

• Operation and noise for luminaires with fans, drivers, or rotating functions.

• Waterproof and sealing inspection for outdoor luminaires, including seals, waterproof connectors, and potting ports; IP rating visually assessed against claimed requirements.

• Dimension, weight, and accessory verification against order requirements.

4. Labels & Packaging

• Product labels: input voltage/current, brand/model, safety certification marks, and permanent markings.

• Packaging protection: inner box, color box, outer carton, shipping marks, sealing method, moisture protection, and cushioning.

• Carton loading check: no short packing, missing items, mixed models, or wrong items. Glass parts, shades, and driver components must be properly protected.

Inspection Methods & AQL Standards

We offer flexible inspection methods based on order size, product value, and risk level:

• Pre-Production Inspection (PPI): Confirms the first article’s workmanship, function, appearance, and on-site safety testing before mass production.

• During Production Inspection (DPI / DUPRO): Conducts sampling during production to identify and correct quality issues in time.

• Pre-shipment Inspection (PSI / FQC): Performs AQL sampling inspection before shipment.

• 100% Full Inspection: For high-value, high-reputation, or precision lighting products, each unit is inspected to ensure zero-defect shipment.

Our inspection follows AQL sampling, ISO 2859-1:2026, and ANSI/ASQ Z1.4 normal inspection single sampling plans. Standard stable orders normally use General Inspection Level II; new suppliers, first orders, and high-end orders may be upgraded to Level III. Mandatory safety items such as grounding resistance and leakage current generally use Special Inspection Level S-1.

Typical defect classification for lighting products: high-voltage breakdown, poor grounding, excessive leakage current, exposed live parts, damaged or exposed power cord, and missing certification marks are CR. Severe lamp body cracks, lamp shade chipping, dead or dark LEDs, driver noise, dimming failure, waterproof failure, and excessive power deviation are MAJ. Minor scratches, rough surfaces, and slight color deviation within tolerance are MIN.

Inspection Process

1. Requirement Communication & Plan Confirmation: The client provides product details, target market, buyer requirements, and order information. We recommend applicable standards and provide a quotation.

2. On-Site Inspection: Inspectors arrive at the factory or warehouse and perform inspection according to AQL sampling or full inspection requirements, covering safety testing, appearance, dimensions, function, packaging, and labels. All findings are documented with photos and data.

3. Defect Classification & Judgment: Defects are classified as CR, MAJ, or MIN, with accurate counts and distribution.

4. Feedback & Corrective Action Follow-up: We immediately inform the factory and client, urge rework, replacement, or rejection, and verify corrective action before shipment.

5. Report Issuance: A bilingual inspection report is issued within 24 hours after inspection, with traceable data and complete photos.
