SUN RUN hydraulic cylinder comply with the criteria set forth in the American Society of Mechanical Engineers standard institute ASME B30.1: 1. Cylinders are designed to have minimum of a 2-to- 1 safety factor on  typical material yield strength; and/or 2. Cylinder design is     

A. Operated through a minimum of 10 cycles of full travel at 110% of rated  load, and    

B. Pressurized 3 times at 150% of pressure with the cylinder extended to   approximately 90% of full stroke, after which the cylinder must be functional at rated load for full stroke and free of leaks. Continuing follow ASME standard, the bolting and hydraulic torque wrench experts at SUN RUN present the definitive course on Bolting Principles and Practices Per ASME PCC-1- series.
