In the modern interior decoration industry, the durability and comfort of materials are crucial factors. The ability of a material to maintain its initial performance over extended periods of use is a key criterion for assessing its quality. The ISO 3385 Foam Constant-load Fatigue Tester GT-LE03 is a specialized piece of equipment designed to address this need. This article will delve into the application principles, testing methods, and industry significance of this device.

Foam materials are widely used in sofas, mattresses, seats, and other products due to their excellent elasticity and softness. However, over time, these foam materials can exhibit fatigue, such as thickness reduction and hardness decrease, due to prolonged pressure. To ensure these materials maintain their durability and comfort in actual use, the GT-LE03 Foam Fatigue Tester is specifically designed to measure the fatigue characteristics of foam materials under constant load conditions.

The working principle of the ISO 3385 Foam Fatigue Tester is simple yet effective. First, a square foam sample is placed on the lower platform of the tester. Then, a smaller indenter repeatedly compresses the sample. During each impact, the tester applies a maximum load within a certain range, simulating real-world compression scenarios. After a predetermined number of impacts, the tester evaluates the sample's thickness reduction and hardness decrease to determine the material's fatigue performance.

This testing method not only effectively simulates the performance of foam materials after extended use but also provides quantitative data that can be used to improve and optimize materials.

The ISO 3385 Foam Constant-load Fatigue Tester GT-LE03 is not only designed according to the ISO 3385 standard but also complies with multiple international and national standards, including GB/T 18941, GB/T 12825, and ASTM D3574-TEST I3, making it recognized worldwide.
