1. Function and Application

The 2 Station Sequential Fatigue Tester is a pneumatically driven cyclic load testing machine designed to apply repeated forces on test specimens to evaluate durability and fatigue life.

This PC-controlled tester allows fully programmable load profiles and precise bidirectional load applications.

It is widely used for evaluating the fatigue performance of seats, foams, cushioning materials, and other mechanical components.

2. Applicable Test Standards

ASTM D3574 – Dynamic Fatigue Test by Constant Force Pounding

ISO 3385 – Flexible Cellular Materials – Determination of Fatigue by Constant Load Pounding

SAE J2896 – Automotive Seat Durability Test Procedures

OEM / Custom Test Specifications – Available upon request
