Specialized testing machine that applies constant load to materials in high-temperature environments for extended periods to measure deformation over time (creep deformation) and time to fracture. Evaluates high-temperature creep characteristics of metallic materials, ceramics, and resin materials to obtain essential data for heat-resistant component design in power plants, aircraft engines, automotive parts, etc. Features integrated structure with temperature control furnace, load application device, and displacement measurement system, capable of testing in compliance with JIS Z 2271, ASTM E139 standards. Distinguished from fatigue testing machines by applying static load for long periods rather than cyclic loading, and from tensile testing machines by conducting long-term tests in high-temperature environments.
