The HD2 Pneumatic Foam Fatigue Tester is a heavy-duty, single-station laboratory testing machine designed to evaluate the dynamic fatigue durability of flexible foam materials under repeated compressive loading. The tester applies cyclic compression to foam specimens using pneumatic actuation, simulating long-term service conditions encountered in seating, mattresses, cushioning, and interior applications. The system supports constant load testing as standard, with constant displacement mode available as an optional configuration.
Standards
The HD2 Pneumatic Foam Fatigue Tester complies with or references the following standards:
ASTM D3574 – Flexible Cellular Materials, Dynamic Fatigue Testing (Constant Force Method)
ISO 3385 – Polymeric materials, flexible cellular — Determination of fatigue by constant-load pounding
GB/T 10807 – Flexible cellular polymeric materials — Determination of compression properties (dynamic reference)
GB/T 6342 – Cellular plastics and rubber — Determination of linear dimensions (specimen preparation reference)
