Office Chair Base Compression Tester – Validate Stability & Load Capacity

BIFMA X5.1, ANSI/BIFMA, and EN 1335 Compliance for Casters & Chair Bases
Our 5-Leg Base Compression Testing Machine rigorously evaluates the structural integrity of chair bases and casters under static, dynamic, and impact loads, ensuring office chairs meet global safety standards for weight capacity and long-term durability.

Core Testing Modes & Features

Multi-Dimensional Load Simulation

Static Compression: Apply vertical forces up to 2000 kg (20 kN) to simulate overweight users.
Cyclic Fatigue Test: 100,000+ cycles at 1–5 Hz to replicate daily seat pressure.
Impact Test: Free-fall drop weights (e.g., 25 kg from 500 mm height) for shock resistance.
Tilt Test: ±15° angular loading to assess base stability on uneven floors.

Precision & Automation

Force Accuracy: ±0.5% FS with dual load cells and laser alignment.
Auto-Centering: Motorized clamps adjust to base diameters (200–600 mm).
Real-Time Monitoring: Track deformation, cracks, or caster failures via HD cameras.

Smart Compliance

Pre-Programmed Standards: BIFMA X5.1 (135 kg static load), EN 1335, GB/T 22894.
Batch Testing: Test up to 10 bases/hour with robotic sample handling (optional).
Data Export: Generate pass/fail reports with force-time graphs and cycle counts.

Applications

✅ Office Chairs: Test metal/plastic bases with nylon or steel casters.
✅ Gaming Chairs: Validate high-load bases (≥150 kg) for commercial use.
✅ Contract Furniture: Ensure hotel/airport chairs withstand 24/7 stress.
✅ Caster Manufacturers: Certify wheel durability under BIFMA X5.1 Annex G.

Why Choose Our Testing System?

✅ Ultra-High Load Capacity: Test bases for heavy-duty chairs (e.g., 500 kg+ capacity).
✅ Modular Design: Add tilt platforms, thermal chambers (-40°C to +80°C), or humidity control.
✅ Zero Downtime: Self-lubricating actuators and overload protection.
✅ Global Certification: Pre-calibrated with NIST-traceable certificates.

FAQ

Q: Can it test bases with wheels (casters) attached?
A: Yes! Test bases with or without casters. Custom fixtures accommodate swivel locks.

Q: How to simulate uneven floor conditions?
A: Use the optional 3D tilting platform (±15° adjustable slope).

Q: What’s the maintenance cost?
A: <$500/year – sealed hydraulic system requires minimal servicing.

Q: Can it test non-standard bases (e.g., 4-leg or 6-leg designs)?
A: Yes – clamps and software adapt to any base geometry.
