BS ISO 3723:2015 pdf download – Hydraulic fluid power — Filter elements — Method for end load test 1 Scope This International Standard specifies a method for verifying the end load rating of a hydraulic fluidpower filter element. It also verifies the ability of a hydraulic fluid power filter element to withstand thedesignated axial loading imposed by installation and use. 2Normative references The following documents, in whole or in part, are normatively referenced in this document and areindispensable for its application. For dated references,only the edition cited applies. For undatedreferences, the latest edition of the referenced document (including any amendments) applies. ISo 2941, Hydraulic fluid power — Filter elements — Verification of collapse/burst pressure ratingISo 2943,Hydraulic fluid power —Filter elements —Verification of material compatibility with fluidsISO 5598,Fluid power systems and components —Vocabulary 3 Terms and definitions For purposes of this document, the terms and definitions in ISO 5598 and the following apply. 3.1 end load axial force applied to the end of a filter element which can cause permanent deformation or seal failure 3.2 rated end load maximum specified axial force which can be applied to a filter element without permanent deformationor seal failure 4Test equipment Suitable weights or mounting fixtures for applying the designated axialloads to simulate theinstallationand usage requirements of the filter element undergoing evaluation. 5 Test procedure 5.1 Subject the filter element to the material compatibility test according to ISo 2943. 5.2 After the 72 h hot soak portion of IS0 2943, cool the filter element to room temperature and subjectit for 5 min to the axial load designated by the filter manufacturer. 6Criteria for acceptance 6.1There shall be no visual evidence of structural, seal, or filter medium failure. 6.2 The filter element shall successfully complete the collapse/burst test in accordance with ISO 2941. 7 Identification statement Use the following statement in test reports, catalogues, and sales literature when electing to comply with this International Standard: “Method of verifying filter element end load rating conforms to ISO 3723, Hydraulic fluid power — Filter elements — Method for end load test.”
