This test method shall be used to verify the structural integrity of certain hydraulic components under pressure impulse-type loading. For the purpose of pressure impulse testing the hydraulic system components shall be divided into passive and active components. This standard establishes the requirements and the procedures for impulse testing of passive hydraulic components only. Unless otherwise specified in the detail specification or in existing component related standards, the following procedures shall be used. Active hydraulic components shall be tested according to tailored test requirements as specified in detail specifications.
