BS ISO 3723:2015 pdf download – Hydraulic fluid power — Filter elements — Method for end load test
This International Standard specifies a method for verifying the end load rating of a hydraulic fluid power filter element. It also verifies the ability of a hydraulic fluid power filter element to withstand the designated axial loading imposed by installation and use.
2 Normative references

3 Terms and definitions
For purposes of this document, the terms and definitions in ISO 5598 and the following apply.
axial force applied to the end of a filter element which can cause permanent deformation or seal failure
rated end load
maximum specified axial force which can be applied to a filter element without permanent deformation or seal failure
4 Test equipment
Suitable weights or mounting fixtures for applying the designated axial loads to simulate the installation and 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 ISO 2943, cool the filter element to room temperature and subject it for 5 min to the axial load designated by the filter manufacturer.
6 Criteria for acceptance
6.1 There 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.
