Dongguan Office Chair Testing

There are several professional companies in Dongguan that offer office chair testing services, covering core indicators such as durability and fatigue life. Here are the specific testing equipment and service introductions:

1. Dongguan Tongming Testing Technology Co., Ltd.
The company provides an Integrated Durability Tester for Office Chair Seats and Backrests (Model TN4008), primarily used to simulate loading conditions in daily use scenarios. Its testing principle involves repeatedly loading and unloading through a seat loading module (600N) and a backrest loading module (192N) at a frequency not exceeding 40 times per minute, completing 200,000 durability tests. This equipment can accurately evaluate the deformation resistance of seats and backrests during long-term use, suitable for corporate R&D verification or quality sampling inspections.

2. Guangdong Derui Testing Equipment Co., Ltd.
Its Derui Computerized Office Chair Seat and Backrest Durability Tester (Model DR-J605) focuses on fatigue life testing. The equipment simulates repetitive loads under normal human sitting postures, with a test stroke of 100-200cpm and a test speed adjustable to 10-30cpm. This tester can detect whether chairs experience structural loosening or material fatigue during long-term use, particularly suitable for quality control of exported products or high-end office chairs.

3. Dongguan Lituo Testing Instruments Co., Ltd.
The company's Office Chair Testing Instrument (Model HD-F738) primarily evaluates the backrest recline fatigue. Designed according to GB/T10357 and QB/T2280-2007 standards, the equipment simulates human weight (typically a standard value of 75kg) by applying an iron disc load on the seat after fixing the chair wheels. It applies a load to the backrest with an adjustable angle (15°90°) and controllable frequency (1030 times per minute), completing 120,000 test cycles. This instrument can test the durability of the backrest adjustment mechanism and overall structural stability, serving as a key device for office chair safety certification.

Selection Recommendations:

• For comprehensive testing of the long-term durability of seats and backrests, Tongming Technology's TN4008 is the preferred choice;
• If focusing on the fatigue life of chairs during dynamic use, Derui Testing's DR-J605 is more suitable;
• For strict compliance with national standards and evaluation of recline functions, Lituo Instruments' HD-F738 is the ideal option.
