Hydraulic fluid power - Filter elements - Method for end load test

ISO 3723:2015 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.

Overview

SIST ISO 3723:2016 is an international standard developed by ISO that specifies a reliable method for testing the end load rating of hydraulic fluid power filter elements. Hydraulic filters are critical components in fluid power systems, where they remove insoluble contaminants from pressurized fluids to maintain system integrity and performance. The filter element itself is the porous device responsible for filtration. This standard ensures that these filter elements can withstand the axial loads imposed during installation and operational use without failure, thus guaranteeing safety and durability.

Key Topics

• End Load Definition: ISO 3723 defines end load as the axial force applied to the end of a filter element that might cause permanent deformation or seal failure.
• Rated End Load: The maximum axial force that can be applied without compromising the structure or sealing of the filter element.
• Test Equipment: The standard specifies use of appropriate weights or mounting fixtures to simulate axial loads experienced during real-world operation.
• Test Procedure:
  • Preconditioning the filter element through fabrication integrity and material compatibility tests.
  • Subjecting the filter element to a specified axial load for 5 minutes at room temperature following a 72-hour hot soak procedure.
• Acceptance Criteria:
  • No visual signs of structural damage, seal failure, or filtration medium failure are permitted.
  • The filter element must pass a collapse/burst resistance test as per ISO 2941 after the axial load test.
• Identification Statement: Manufacturers can declare compliance with the standard in documentation by referencing the prescribed ISO 3723 conformance statement.

Applications

SIST ISO 3723:2016 is essential for manufacturers and quality assurance teams involved in designing and testing hydraulic fluid power systems. Its practical applications include:

• Filter Element Design Validation: Confirming a filter element’s ability to withstand end loads ensures reliability in hydraulic machinery, mobile equipment, and industrial automation.
• Quality Control: This test method allows consistent verification of production filter elements against axial load specifications, preventing early filter failure.
• Product Certification: Compliance provides confidence to buyers and users regarding the mechanical robustness of filter elements.
• System Safety Improvement: By verifying that filters endure installation and operational stresses, it helps protect critical hydraulic components and minimize downtime.

Related Standards

SIST ISO 3723:2016 should be used in conjunction with:

• ISO 2941 – Hydraulic fluid power - Filter elements - Verification of collapse/burst resistance. This standard is referenced for the collapse/burst test criteria integral to end load acceptance.
• ISO 2943 – Hydraulic fluid power - Filter elements - Verification of material compatibility with fluids. It addresses the fabrication integrity and hot soak procedure preceding the end load test.
• ISO 5598 – Fluid power systems and components - Vocabulary. It provides relevant terminology to ensure clarity and uniform understanding in fluid power contexts.
