1.1 This standard provides: 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 (see 3.3) can be rated as integral parts of hydraulic valves or as an independent components.
