For those designing systems and writing specifications, sizing and selecting hydraulic components for mobile and industrial operating machinery. Hydraulic specialists draft schematics using standard fluid power symbols. Hydraulic specialists design systems which are drafted to fluid power essential practices supported by National and International Standards. Hydraulic Specialist certification requires a three (3) hour written test. If you’re interested in testing for the HS level certification, registration information can be found here
