Test Method of Pneumatic Cylinder´s life

Pneumatic cylinder is an important element in pneumatic fluid power systems, and its performance determines the system´s performance. Efficient and economical production requires highly reliable machines and equipment, so its reliability must be grasped. However, there were no evaluating standard and test methods in ISO standard. The paper presents a method about the reliability test circuit of pneumatic cylinders, which include test conditions, test circuit, threshold levels, and data analyses and finally give a test example; these permit the assessment of pneumatic cylinders´ reliability.
