Our Certificate

SGS

SGS (Société Générale de Surveillance) is the world's leading independent inspection, testing, and certification organization, founded in Switzerland. For furniture products such as chairs, SGS testing involves a series of laboratory evaluations to ensure compliance with international standards in safety, performance, quality, and regulatory compliance. Testing typically includes physical strength tests (e.g., load-bearing and durability), chemical analysis (e.g., non-toxic materials), and environmental compliance checks (e.g., adherence to eco-regulations).

BIFMA

1.Core Functions of BIFMA Testing
The testing standards (e.g., BIFMA X5.1/X6.1) established by BIFMA (Business and Institutional Furniture Manufacturers Association) serve as the authoritative certification for the North American office furniture industry, specifically designed to evaluate the safety, durability, and compliance of commercial chairs. Its core values are reflected in:
2.Safety Risk Prevention (Core Value)
Preventing Structural Failure: Validates weight-bearing limits under extreme conditions through static load tests (simulating 136kg overload pressure) and impact drop tests (sudden force on seat/backrest).
3.North American Market Access Passport
Mandatory Certification: Required by U.S. government procurement (GSA contracts) and major retailers like Walmart.
Regulatory Equivalence: BIFMA compliance satisfies the U.S. Consumer Product Safety Improvement Act (CPSIA) and Canada's SOR/2016-188.
Cost Case: Non-certified products entering North America may incur 30% tariff surcharges.
4.Optimizing Product Design & Enterprise Costs
Pre-production Diagnostics: Early testing exposes defects (e.g., faulty cylinder selection causing explosions, insufficient nylon caster hardness), avoiding mass recalls (single recall cost ≥$5M).
Lifespan Prediction: Chairs passing 120,000 cycle tests theoretically last ≥10 years (8 hours daily use).

Zertifikat

TUV gas spring certification primarily involves aspects such as material, pressure rating, and certification status. The material and pressure rating of a gas spring are crucial indicators for evaluating its safety and durability. TUV-certified gas springs generally exhibit superior sealing performance and stability, along with enhanced service life and load-bearing capacity. The strength class of gas springs is typically defined by the EN16955 (European standard), with Class 3 or Class 4 gas springs offering highly reliable strength and can be used with confidence. Regarding certification status, priority should be given to gas springs certified by SGS or TUV against the BIFMA standard; personally, I recommend selecting those with at least SGS Class 3 certification or higher. Certification marks can be observed as steel stamps on the gas spring, such as TUV Class 4 certification, EN16955Class4TUV, or EN16955Class4SGS.
