Office Chair Reciprocating Impact Tester CX-8301

The Office Chair Reciprocating Impact Tester CX-8301 is a professional device designed to evaluate the durability and structural stability of office chairs. Its core function is to simulate dynamic impact scenarios during long-term use, testing the ability of specimens (such as office chairs) to withstand fatigue stress and wear. The following provides an explanation from three aspects: technical principles, functional features, and application scenarios.

I. Technical Principles and Standard Basis
This device is designed in accordance with QB/T 2280-2007 (China Light Industry Standard) Clauses 6.6.3 and 6.6.13.1 and BIFMA_X5.1-2011 (American Office Furniture Standard) Clauses 8 and 11.3. It achieves reciprocating free-fall impact on specimens through electromagnetic valve-controlled electromagnets. Its core parameters include:

• Impact Parameters: The electromagnet can lift weights up to 200kg, with an adjustable stroke of 0-300mm, a test speed of 10-30 cycles per minute, and an adjustable interval time of 0-99 seconds, covering the testing needs of office chairs made of different materials.
• Control and Display: It employs microcomputer automatic control, allowing parameter setting via a 7-inch full-color LCD touch screen. It displays the test cycle count in real-time (0-9,999,999 cycles can be set), saves data to computer memory or a USB drive, and automatically generates test reports.
• Safety Mechanism: Equipped with position sensors and a dual-system for pressure regulation, oil filtration, and water filtration, it automatically stops when the specimen is damaged or the deformation exceeds the standard, retaining test results for analysis.

II. Functional Features and Operational Advantages

1. High Automation: The entire process, from setting the test cycle count, executing impact actions, to recording results, requires no manual intervention, reducing human error.
2. Environmental Adaptability: It operates in a temperature range of 5℃-40℃ and a relative humidity of 20%-80%RH, requiring a level and flat test surface to ensure testing stability.
3. Data Traceability: Test reports include key data such as impact cycle count and damage time, providing quantitative evidence for product improvement.
4. Complete Accessories: The device comes standard with one sandbag (for simulating loads), a main unit, a control cabinet, and a full set of documents (instruction manual, certificate of conformity, warranty card), facilitating rapid deployment.

III. Typical Application Scenarios
This device is primarily used in the quality control process of office chair manufacturers. By simulating frequent sitting, standing, and moving actions by users, it verifies the fatigue resistance of components such as the seat, backrest, and five-star base. For example, it tests the rebound rate of seat foam after long-term compression or the structural stability of the five-star base under impact, ensuring products meet industry standards and user safety requirements. Additionally, third-party testing institutions can use it to issue authoritative test reports, aiding market access certification.
