It is, therefore, essential that, in conducting these tests, all appropriate safety precautions be strictly adhered to. Attention is drawn to the danger of burst, fine jets

40、(which can penetrate the skin) and energy release of expanding gases. To reduce the hazard of energy release, bleed air out of test specimens prior to pressure testing. Tests shall be set up and performed by properly trained personnel.1 ScopeThis document specifies uniform test methods for evaluatin

41、g the performance of hoses and hose assemblies (hoses and attached hose fittings) used in hydraulic fluid power systems.Specific tests and performance criteria for evaluating hoses and hose assemblies used in hydraulic applications are in accordance with the requirements of the respective product (h

42、oses or hose fitting) specifications.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
