Furniture Inspection Defect Classification and On-site Inspection Key Points

I. Defect Classification:

1. Structural Safety Defects: Includes loose screws, unstable frames, and easily detached components.

2. Material Defects: Includes cracks, deformation, decay, color difference, and inconsistent materials.

3. Workmanship Defects: Includes rough surfaces, uneven seams, uneven coatings, and loose joints.

4. Functional Performance Defects: Includes unstable chairs, insufficiently loaded tables, and uncomfortable beds.

5. Environmental Compliance Defects: Includes materials and workmanship that contain hazardous substances and do not meet environmental standards.

II. On-site Inspection Items：

1. Structural Safety Test: Performs shaking, pushing, pulling, and load-bearing tests to ensure the structural stability of the furniture.

2. Material Defect Inspection: Assess material integrity and consistency through visual and tactile inspection.

3. Workmanship Defect Assessment: Visually inspects the furniture to assess its integrity and consistency. A tactile inspection ensures the precision of the furniture surface and joints.

4. Functional Performance Testing: Through actual operation of the furniture, the functional performance is tested to ensure that it meets the design requirements.

5. Environmental Compliance Testing: Professional equipment is used to test the content of harmful substances in furniture materials.

III. Judgment Criteria

1. Structural Safety: During the inspection, the furniture shows no obvious loosening, falling, or deformation, and can withstand normal operating loads.

2. Material Defects: The furniture materials show no obvious cracks, deformation, or decay, and the color and texture are consistent.

3. Workmanship Defects: The furniture surfaces and joints show no obvious flaws, and the coating is even and the joints are tight.

4. Functional Performance: The furniture can normally perform its designed functions without any abnormal noise or jamming.

5. Environmental Compliance: The content of harmful substances in the furniture materials meets national or international environmental standards.
