Office Chair Acceptance Criteria

Office chair acceptance criteria cover official standards, group standards, and finished product inspection standards, as detailed below:

I. Official Standards

1. QB/T 2280 - 2016 'Office Furniture - Office Chairs': Specifies the classification, technical requirements, and test methods for office chairs. Key indicators include an adjustable seat height range of not less than 60mm, along with safety requirements such as structural stability and load-bearing capacity.
2. QB/T 5618 - 2021 'Measurement Method for Body Pressure Distribution of Office Chairs': Standardizes the testing procedures and methods for body pressure distribution, ensuring that chair designs comply with ergonomic principles and enhance seating comfort.

II. Group Standards

1. T/SPEMF 0003 - 2021 'Office Chairs': Refines classifications and supplements safety requirements, including flame retardancy, limits on harmful substances (such as formaldehyde and heavy metals), as well as comfort (seat cushion hardness, backrest support) and durability (abrasion resistance testing, fatigue testing) indicators.
2. T/SZFA 3006 - 2021 'Office Chairs': Applicable to indoor office chairs, it specifies product classifications, technical requirements, inspection rules, and packaging requirements, emphasizing the use of environmentally friendly materials and structural safety.
3. T/CNFA 016 - 2021 'Quality and Safety Grading Evaluation of Office Chairs': Defines rules for grading quality and safety, such as evaluating products as superior or qualified based on materials, craftsmanship, and performance indicators.

III. Finished Product Inspection Standards

1. Components and Assembly: All components must be complete and correctly sized, with no missing or incorrectly installed parts; assembly should be straightforward according to the instructions, with tight-fitting parts and no looseness or jamming.
2. Appearance Requirements: The overall structure should be free from skewing, with full and non-depressed filling; colors should be uniform with no noticeable color differences; hardware should be free from burrs or rust, with a clean and stain-free surface; fabrics or leather should be free from damage or loose threads.
3. Dimensions and Tolerances: Seat height should be ≥380mm, seat depth 340-350mm, back height ≥275mm, and lifting travel ≥60mm; the backrest eccentricity should be ≤140mm, overall symmetry ≤6mm, and seat surface level deviation ≤6mm.
4. Function Testing: Lifting, rotation, and reclining functions should operate smoothly without abnormal noises or jamming; seating should be comfortable with no localized pressure points; safety mechanisms (such as explosion-proof gas rods and locking devices) should be reliable.
5. Packaging and Accessories: Packaging materials should be intact with clear printed information; accessories (such as instruction manuals and warranty cards) should be complete; after drop testing, packaging should remain undamaged with all internal items intact.
