Office Chair Fire Protection Standards

Office chair fire protection standards are mainly divided into two categories: domestic standards and foreign standards. The specific content is as follows:

Domestic Standards

1. GB 17927.1 - 2011 and GB 17927.2 - 2011
   These two standards are upholstered furniture flame-retardant standards, testing the ignition conditions for different fire sources. GB 17927.1 - 2011 simulates the ignition scenario of a smoldering cigarette, while GB 17927.2 - 2011 simulates the ignition scenario of a match flame, evaluating the flame-retardant performance of office chairs when in contact with fire sources through testing.

2. GB/T 17927
   This standard focuses on evaluating the combustion performance of office chair products, with test content including ease of ignition, flame spread rate, and combustion duration. The test scope covers the overall structure of office chairs, including components such as seat fabric, filling materials, and frames, ensuring that all parts meet fire protection requirements.

3. QB/T 2280 - 2016 'Office Furniture - Office Chairs'
   The flame retardancy of office chairs must comply with this standard, which clearly specifies the specific requirements for the fire protection performance of office chairs, providing technical basis for product quality.

4. GB17927—2024 'Safety Technical Specification for Flame Retardancy of Furniture'
   This standard specifies the requirements, inspection rules, and labeling for the flame retardancy of furniture, and describes the test methods. Among them, Flame Retardancy Class I passes the cigarette ignition source test and is suitable for general households; Flame Retardancy Class II passes the simulated match flame test and is suitable for other public places except for nursing homes, public entertainment venues, and hospital wards.

Foreign Standards

1. British BS 5852 Standard
   This standard uses six different ignition sources for testing, with clear requirements for parameters such as smoldering time and flame removal duration, comprehensively evaluating the flame-retardant performance of office chairs under complex fire source conditions.

2. American NFPA 260 Standard
   The Class I pass criteria specify that the maximum char length of the seat back covering fabric should not exceed 38 millimeters, the barrier material should not exceed 51 millimeters, and it should not continue to ignite. This standard strictly controls the fire protection performance of office chairs through quantitative indicators, ensuring safety in use.
