National Standard Certification for Office Chairs
The national standard certification for office chairs primarily involves two standards: QB/T 2280-2016 and GB/T 10357.3-2025. Here is a detailed explanation:
QB/T 2280-2016 'Office Chairs' is the most core domestic standard in the office chair industry, issued by the Ministry of Industry and Information Technology, and applicable to various types of office chair products. This standard sets clear requirements for key indicators such as safety, durability, and environmental protection of office chairs. For example, in durability testing, differentiated standards are set for office chairs in different usage scenarios: Type I office chairs (high-intensity usage scenarios) require 100,000 cycles of backrest adjustment without damage, while Type II office chairs (ordinary usage scenarios) require 50,000 cycles without damage. In seat durability testing, Type I products must withstand 120,000 vertical loads without structural failure. Additionally, the standard imposes restrictions on environmental protection indicators such as formaldehyde emissions and heavy metal content to ensure products meet indoor air quality requirements.
GB/T 10357.3-2025 'Furniture Mechanical Performance Testing - Part 3: Strength and Durability of Chairs and Stools' is a general standard for testing the mechanical performance of furniture, applicable to verifying the strength of chairs and stools. This standard evaluates product performance through two major methods: static load testing and dynamic fatigue testing. Static testing includes ultimate load-bearing capacity tests for seats, backrests, and armrests, such as the seat must withstand a vertical pressure of 1600N without breaking. Dynamic testing simulates long-term usage scenarios, such as the seat completing 60,000 reciprocating loads without damage. This standard provides a scientific quantitative basis for the durability of office chairs and complements QB/T 2280-2016.
When applying for national standard certification, enterprises must undergo full-project testing by third-party testing institutions in accordance with the above standards. The test report is the core proof document of product compliance. After certification, products can be affixed with the CQC mark or CCC mark (if involving mandatory certification items), indicating they meet domestic market access requirements. For exported products, enterprises must also simultaneously meet the international standards of the target market, such as the EN 1335 standard in the European Union or the BIFMA standard in the United States.
