Universal Compression Fatigue Testing Machine
The Universal Compression Fatigue Testing Machine is designed for fixed-displacement compression fatigue testing of springs and elastic components. Originally developed for mattress spring durability evaluation, the system has been expanded to support a wide range of compression fatigue applications. It provides stable cyclic loading, reliable failure detection, and long-term endurance testing under controlled displacement conditions.
Application
This machine is used for compression fatigue and durability testing of elastic and load-bearing components, including:
Mattress springs and spring units
Furniture springs and cushioning systems
Automotive seat springs and suspension springs
Rubber blocks and elastomer components
Metal coil springs and compression elements
Industrial elastic components subjected to repeated compression
It is suitable for quality control, product development, and endurance testing in furniture, automotive, bedding, and component manufacturing industries.
Standards
The testing system is designed to comply with or support the following relevant international and industry standards (depending on configuration and test method):
(1) ISO 3385 – Mattress assessment — Durability testing
(2) ISO 7500-1 – Verification of static uniaxial testing machines
(3) ASTM F1566 – Standard Test Methods for Evaluation of Mattress Durability
(4) ASTM E9 – Compression testing of metallic materials
(5) ASTM D575 – Rubber properties in compression
(6) SAE J157 – Testing of automotive seat cushioning and spring components
(7) GB/T 26706 – Mattress durability and fatigue testing
(8) GB/T 7757 – Rubber compression set test methods
