14 Identification statement
Specifies: - test and statistical methods for generating fatigue distribution data; - test and statistical methods for conducting a verification of the pressure ratings on fluid power hydraulic valves; - common requirements and an industry-wide philosophy in judging one type of pressure capability for hydraulic valves typically used in fluid power applications; - uniform methods of product comparison; - hydraulic valves may contain one or more pressure zones. Each pressure zone may have pressure ratings based on a maximum differential pressure to an adjacent lower pressure zone or atmosphere; - attachments can be rated as integral parts of hydraulic valves or as an independent component.
