Hydraulic Test Standard

Historically hydraulic institute standards have been divided into 1 series standards covering centrifugal pumps and 2 series standards covering vertical pumps.

Hydraulic test standard. E1003 13 2018 standard practice for hydrostatic leak testing leakage rate internal pressure hydrostatic leak test. It supersedes two test standards. A hydrostatic test is a way in which pressure vessels such as pipelines plumbing gas cylinders boilers and fuel tanks can be tested for strength and leaks. Hydraulic fluid power electrical connectors for use with industrial hydraulic integrated proportional valves dimensions and requirements nfpa t3 4 7 r2 2000 r2019 accumulator pressure rating supplement to nfpa t2 6 1 r2 2000 method for verifying the fatigue and establishing the burst pressure ratings of the pressure.

The cylinder will be rejected if it functions erratically. The hydraulic institute s new test standard ansi hi 14 6 rotodynamic pumps for hydraulic performance acceptance tests provides the pump community with a globally accepted standard for testing rotodynamic pumps of the centrifugal mixed flow and axial types. Ansi hi 1 6 centrifugal pump tests and ansi hi 2 6 vertical pump tests. Pumps systems february 2013 the hydraulic institute s new test standard ansi hi 14 6 rotodynamic pumps for hydraulic performance acceptance tests provides the pump community with a globally accepted standard for testing rotodynamic pumps of the centrifugal mixed flow and axial types.

This sae aerospace standard as establishes the requirements and procedures for impulse testing of hose tubing and fitting assemblies for use in aerospace hydraulic systems of 8000 psi nominal operating pressure or less. The test involves filling the vessel or pipe system with a liquid usually water which may be dyed to aid in visual leak detection and pressurization of the vessel to the specified test pressure. Ansi hi 1 6 for centrifugal pumps and ansi hi 2 6 for vertical pumps. It also refers to standard impulse test.

Testing for hydraulic equipment is usually performed with the help of complex test systems or test stands. As noted in the names of the standards the old centrifugal and vertical pumps are grouped under the name rotodynamic which is an improvement in the accuracy of the. Erratic function is excessive chatter slapstrick stalling and uncorrectable misstaging. 1 function test once the cylinder is placed on the test stand and hydraulic lines attached the cylinder will be cycled its full stroke a minimum of three 3 full cycles.

It supersedes two test standards. The test stand acts as a fluid supply source and can be adjusted to supply the required fluid at the flows pressures and temperatures necessary for the test.
