Sanhe Office Chair Impact Tester

No direct information was retrieved for 'Sanhe Office Chair Impact Tester', but an office chair impact tester is a specialized device used to evaluate the strength and durability of the backrest or seat of an office chair under repeated loading. Its core principle involves fixing the casters, applying a load, and conducting impact tests on key parts with preset parameters.

Common Types and Core Parameters

1. Office Chair Repeated Backrest Impact Tester

   • Force Application Range: 0 - 150 pounds (approximately 0 - 68 kgf), simulating different impact strengths.
   • Force Application Stroke: Maximum 18 inches (approximately 457 mm), covering the range of backrest movement.
   • Test Speed: Commonly 16 or 20 cycles per minute, supporting high-frequency durability testing.
   • Seat Load: Requires the application of standard weights (such as 100 or 225 pounds) to simulate actual usage weight.
   • Backrest Force Application Point Height: Adjustable range of 500 - 1200 mm, suitable for different chair types.
   • Control System: Equipped with an LCD counter (counting range 0 - 999,999 cycles) and power-off memory function to ensure data continuity.
   • Machine Dimensions: Approximately 136 cm in length × 66 cm in width × 140 cm in height, weighing about 549 kg, requiring stable support.
   • Power Requirements: Single-phase AC220V, current approximately 3A, suitable for conventional laboratory environments.

2. Office Chair Impact Durability Tester

   • Standard Compliance: Complies with the US BIFMA standard, ensuring internationally recognized test results.
   • Impact Mode: Uses a magnetic chuck to drive a 125-pound sandbag, impacting 100,000 times at a frequency of 10 - 30 cycles per minute to simulate long-term usage scenarios.
   • Impact Load: Supports adjustable 0 - 300N, covering testing needs for light to heavy-duty office chairs.
   • Control System: Adopts a PLC touch screen for intuitive operation and precise data recording.
   • Machine Dimensions: Approximately 960 × 660 × 920 mm, with a compact structure that saves space.

3. Seat Impact Tester

   • Test Function: Uses a 16-inch diameter, 125-pound sandbag to impact the seat from a height of 1 inch at a speed of 10 - 30 cycles per minute, completing 100,000 tests.
   • Static Pressure Test: Some devices integrate a static pressure function, using an 8-inch diameter, 165-pound weight block to apply pressure to the front corners of the chair to assess structural stability.

Application Scenarios

Such devices are widely used in the quality inspection departments of office chair manufacturers, third-party testing institutions, and R&D laboratories. By simulating repeated impacts during actual use, they can identify issues such as material fatigue and structural looseness in advance, ensuring that products meet safety and durability standards.
