Office Chair National Standard Testing
Office chair national standard testing primarily covers aspects such as structural safety, limits on harmful substances, dissection of core components, comprehensive performance of finished products, and environmental safety of materials.
Structural Safety Testing: Based on the 'Technical Specification for Furniture Structural Safety' (GB 28008โ2024), basic safety items of office chairs are tested, including rounding and chamfering, the firmness of component connections, sharp edges and corners, vertical moving parts, anti-detachment devices or warning signs, caster locking, and overall product stability. These requirements aim to ensure that office chairs do not cause harm to users during use, such as preventing scratches from sharp edges and injuries from falling components.
Limits on Harmful Substances Testing: According to the 'Limits on Harmful Substances in Furniture' (GB 18584โ2024) standard, requirements for limiting harmful substances in office chairs are regulated. Definitions and limit values for total volatile organic compounds are added, limit values for migratable harmful element heavy metals are clarified, testing indicators for phthalates, polycyclic aromatic hydrocarbons, and decomposable aromatic amine dyes are unified, and a new non-destructive testing method for formaldehyde emission is proposed. These regulations help reduce the potential threat of harmful substances in office chairs to user health.
Dissection of Core Components Testing: Core components of office chairs, such as gas springs, five-star bases, chassis, casters, and armrests, are dissected and tested to assess whether their quality and performance meet standard requirements. This helps ensure that core components of office chairs do not fail or become damaged during use.
Comprehensive Performance Testing of Finished Products: The stability, strength, durability, flame retardancy, and other comprehensive performance aspects of office chairs are tested. These performance indicators are directly related to the service life and safety of office chairs and serve as important bases for evaluating their quality.
Environmental Safety Testing of Materials: The materials used in office chairs are tested for environmental safety to ensure they comply with relevant environmental standards. This helps reduce the pollution caused by office chairs during production and use.
