§ 45.1-161.274. Hydraulic hoses.
All hydraulic hoses used on equipment purchased after January 1, 1986, shall be clearly stamped or labeled by the hydraulic hose manufacturer to indicate the manufacturer's rated pressure in pounds per square inch (psi). For hoses purchased after January 1, 1989, the rated pressure shall be permanently affixed on the outer surface of the hose and repeated at least every two feet. Hoses purchased and installed on automatic displacement hydraulic systems shall have a four-to-one safety factor based on the ratio between minimum burst pressure and the setting of the hydraulic unloading system (such as a relief valve) or shall meet the minimum hose pressure requirements set by the hydraulic equipment manufacturer per the applicable hose standards for each type of equipment. No hydraulic hose shall be used in an application where the hydraulic unloading system is set higher than the hose's rated pressure.
