低週波疲勞 (LCF) 測試是是材料測試中成長的領域，從不斷增加的航太、汽車和電力產業的需求，特別顯著。 ISO 12016 和 ASTM E606指定應變控制疲勞試驗，用於模擬機械裝載到塑料區域的標準做法。這種測試通常是在非常高的溫度，以複製通過渦輪葉片在氣體渦輪機和飛機引擎所經歷使用的條件下進行。
Low Cycle Fatigue (LCF) testing is a growing area of materials testing, driven in particular by increasing demand from the aerospace, automotive and power generation industries. ISO 12016 and ASTM E606 specify the standard practice for strain controlled fatigue testing, used for simulating mechanical loading into the plastic region. This testing is typically carried out at very high temperatures to replicate the service conditions experienced by turbine blades in both gas turbines and jet engines.

8862 systems have been the industry choice for Low Cycle Fatigue (LCF) testing for decades and are now fully integrated with our latest controller platform. Instron® has developed this system specifically to address the challenges of reverse-stress Low Cycle Fatigue and Thermomechanical Fatigue (TMF) testing. The unique actuator technology utilizes an all-electric, backlash free, ball-screw drive eliminating the need for hydraulic infrastructure to support the machine.

Instron's revolutionary approach to furnace control solves one of the challenges of high temperature which is rarely discussed. Temperature control is notoriously challenging and dependent on expert technician's knowledge to configure, tune and optimise multiple temperature controllers to achieve the desired heating rate, set point and temperature gradients.

The 2527 Series load cells are designed for use with Dynamic Testing Systems; offering exceptional performance with the ability to measure forces as low as 1/250th of the force capacity to an accuracy of 0.5% of reading. Automatic transducer recognition and electrical calibration, makes them easy to use. The load cells can withstand loads up to 150% of their force capacity without damage and 300% without mechanical failure. All Instron load cells are individually temperature-compensated and tested for accuracy and repeatability on calibration apparatus that is traceable to international standards, with a measurement uncertainty that does not exceed one-third of the permissible error of the load cell.
