European Institution Office Chair

European institution office chairs must comply with the EN 1335 standard and pass CE certification to enter the EU market. The core requirements cover four aspects: regulatory standards, certification dimensions, processes, and supervision, as detailed below:

I. EN 1335 Standard System
EN 1335 is the core regulation formulated by the EU for office chairs, consisting of five parts:

1. General Safety Requirements: Defines the basic safety parameters of office chairs, such as structural stability and edge rounding, to ensure no direct physical harm risks.
2. Type-Specific Specifications: Parts two to five set differentiated indicators for different usage scenarios (e.g., manager chairs, conference chairs). For example, EN 1335-1 specifies the finished product's dimensions (seat depth, seat width, backrest height, etc.), while EN 1335-2:2018, after updates, unifies safety performance testing methods, adopting the EN 1728:2012 standard for strength and durability testing (e.g., repeated loading of the seat surface, caster wear cycle counts, etc.).

II. Core Dimensions of CE Certification
CE certification evaluates office chair compliance from three aspects:

1. Mechanical Safety: Verifies structural stability through static load testing (e.g., the seat surface withstands 1100N pressure for 24 hours), dynamic impact testing (e.g., the backrest withstands 330N impact force), and caster wear testing (e.g., 50,000 reciprocating rolls).
2. Ergonomics: Requires seats to have multi-dimensional adjustment functions (e.g., seat height, backrest tilt angle, armrest height), with lumbar support conforming to the human spine curve to accommodate users of different body types and reduce the risk of prolonged sitting fatigue.
3. Material Safety: Prohibits the use of harmful substances such as lead and cadmium. Materials must pass flame-retardant tests (e.g., EN 1021-1/2 standards) to ensure the burning speed is below the specified threshold.

III. Certification Process and Risk Management
Manufacturers typically complete conformity assessment through internal production control, requiring the establishment of technical documentation (including design drawings, test reports, and declarations of conformity). Risk assessment is a critical step, involving the systematic identification of potential hazards (e.g., tipping, pinching, harmful gas emissions) and reducing risks to acceptable levels through technical measures (e.g., increasing base weight, optimizing structural gaps). Involvement by a notified body is voluntary but can enhance market trust.

IV. Market Supervision and Compliance Maintenance
EU member state regulatory authorities conduct spot checks on products bearing the CE mark. If non-compliance with regulations (e.g., material exceedances, structural defects) is found, products will be ordered off the shelves, recalled, or even legal action taken. Manufacturers must regularly update technical documentation to ensure ongoing compliance with standard requirements.
