Certification level and evaluation system

Ergonomics-Furniture certification adopts a pass/fail assessment method, and no star rating is set. The focus is on whether the product meets the ergonomical technical requirements and testing methods specified in the standard. The certification is based on the GB/T 39223 series of standards and the implementation rules formulated by the certification body, and comprehensively evaluates the product:

• Testing method: Use professional equipment such as body pressure distribution measurement system for quantitative testing. The sensor adopts an array of resistive weaving sensing units. The weaving material is soft and has a ductility of up to 120%, which can perfectly fit the human body curve for accurate measurement.
• Evaluation indicators: Depending on different product types, focus on the seat surface body pressure distribution, peak pressure, waist-to-hip pressure ratio, key size parameters, operating force and other indicators.
• User experience verification: Comprehensive evaluation is carried out based on the user's emotional reactions, trust reactions, preference reactions, sensory reactions, physiological and psychological reactions, behaviors and performance before, during and after use.

Ergonomics

of the certification process-Furniture certification is usually divided into the following stages:

• application and acceptance: Submit application materials (business license, product description, product drawings, raw material list, production process flow chart, etc.), and the certification body conducts application review to confirm the product and The company has the basic requirements for certification.
• Document review: Review product data for compliance with GB/T 39223 series standards and certification implementation rules, and verify product design concepts and ergonomic design instructions.
• Product sampling and testing: The certification body shall appoint personnel to go to the production site or finished product warehouse to conduct sampling, and the samples will be sent to a qualified laboratory for testing. Testing items include key size measurement, body pressure distribution test, operating force test, stability test, etc.
• Initial factory inspection: Carry out on-site audits of production companies, including personnel interviews, document records inspections, production site inspections, quality control system operation inspections, etc., to evaluate the company's quality assurance capabilities and its ability to continuously and stably produce qualified products.
• Rectification and review: For the non-conformities found in the review, the enterprise completes the rectification within the specified time limit and submits evidence for review by the review team.
• Certification decision and certification: After passing the technical review, a certification certificate will be issued to confirm that the product meets the certification requirements. The certificate is valid for three years. Certified products may use the certification mark on their packaging or promotional materials.
• Supervision after certification: Supervision and review shall be carried out once a year after certification.
