A Comprehensive Guide to Inspection and Certification of Belt Products

A good belt can reflect a man's taste. When purchasing or inspecting belts, inspectors need to conduct tests and certifications in accordance with uniform standards. This article sorts out the key points of belt inspection from aspects such as appearance quality, testing methods, and packaging, and relates them to the requirements of factory audit and product certification.

I. Appearance Quality Requirements (Core of Inspection)
All goods must fully comply with the leather, leather color and leather texture requirements of the original version, and the specifications and accessories must be consistent with the original version.

1. Specification requirements
The allowable error for length is ±5mm, width ±1mm, and thickness ±1mm.

The width of the leather ring is no less than 8mm, and the thickness is 1.2-1.8mm.

The hole spacing is 24 to 26mm, and the distance from the tail end is 75 to 100mm.

2. Cortex
Firm and plump, without loose shells or cracked surfaces, with uniform thickness and no severe knife wounds.

Width ≤20mm series, thickness ≥1.8mm; Series with width >20mm and thickness ≥2.0mm.

3. Belt body
Neat and clean, the accessories are smooth without burrs, and there is no delamination, discoloration or paint peeling.

4. Oil edge
Smooth and undulating, without lumps, no fading, no edge cracking, no oil edge overflow, no sticky glue or other phenomena.

5. With holes
Vertically centered, with equal hole spacing, the error is all ≤2mm.

6. Socket nails
The distances are equal, the installation is firm, there is no severe paint peeling or flaking, the opening is smooth, neither too loose nor too tight.

7. Shake the head (at the fastening point)
Minor cracks are allowed.

8. With a bottom
Basically smooth and uniform, without fuzzing or scratches.

9. Spacer (gasket
The color is basically in harmony with the body of the belt, and the size is moderate.

10. Sewing requirements
The seam spacing is 1.5 to 3mm, the stitch is clear and straight, the tightness is consistent, and there is no severe skew.

The exposed area should have no missed stitches, loose threads, double needle holes, and no more than one missed thread. The thread ends should not be exposed.

11. With buckle
No spots, no oxidation, no cracks, no paint peeling, and the LOGO is clear and upright.

The above appearance inspection items are the basis of goods inspection and also an important reference for evaluating the factory's technological level and incoming material control during factory inspection.

Ii. Testing Methods (Inspection and Measurement)
Sensory inspection is the main method, combined with measuring tools.

Measure with a meter stick. The minimum scale is 1mm.

All other items shall be carried out in accordance with the inspection methods for women's bags, men's bags and sports bags.

Important judgment: If any defect occurs that affects the basic usage function of the product, it will be classified as an unqualified product. This determination rule should be incorporated into the certification process.

Iii. Packaging and Labeling Inspection (Inspection and Certification Requirements)
1. Outer packaging
Clean, beautiful and smooth, free of stains and damages.

2. Inner packaging
The paper should be fully stuffed. After packaging with white copy paper, it should be placed in a white moisture-proof bag or a white transparent bag.

3. Tag and barcode
The tag information is complete and correct, and the barcode is pasted in the right position.

4. Outer box marking
The side of the carton should include correct information such as the order number, style number, color, quantity and the corresponding factory.

Packaging inspection is the final step of goods inspection and should also comply with the certification mark requirements of the target market (such as CE, REACH, etc.).

Iv. Association between Factory audit and Product Certification
Supplier factory inspection: It is necessary to verify the processes of leather material cutting, oiling edge, drilling, nailing, sewing, etc. of the belt manufacturing enterprise. Calibration records of inspection equipment (calipers, thickness gauges, tensiometers, etc.); Qualifications of inspection personnel; And the certification of hazardous substances in raw materials (leather, oil edge materials, hardware buckles) (such as hexavalent chromium, azo dyes, etc.).

Product certification: Export belts must comply with the certification standards of the target market (such as EU REACH, US CPSIA, China GB 20400, etc.). When inspecting the goods, check the consistency between the product labels, tags and certifications.

Continuous improvement: For non-conformities identified during inspection (such as oil edge burst and hole deviation), a rectification report should be formed, followed up in a closed loop through factory inspection, and a quality traceability file should be established.

Through the above inspection, testing, factory inspection and certification processes, it can be ensured that the belt products fully meet the standards in terms of dimensional accuracy, material safety, durability and packaging compliance, thereby enhancing the brand's reputation.
