ISO 8637-2 Cone Reference Connector

Product Overview

Blood circuit connectors used in extracorporeal treatment systems must provide reliable mechanical engagement with their intended mating components. The geometry of the mating interface is important when evaluating connector compatibility and performance under defined laboratory conditions.

The KP-8637F4 Cone Reference Connector provides a standardized conical mating surface for testing blood socket connectors associated with ISO 8637-2. Its defined geometry allows laboratories to establish a consistent mechanical interface when arranging connector tests.

Unlike a dimensional inspection gauge, which is used to assess geometric engagement against dimensional limits, a reference connector serves as the specified mating component within a connector test arrangement. The required test conditions and measurements are provided by the associated test equipment and procedure.

The KP-8637F4 is manufactured from 440C stainless steel, with a specified hardness of HRC 58–60 and critical surface roughness not exceeding Ra 0.8 μm. Its compact construction makes it suitable for integration into compatible laboratory fixtures and connector test arrangements.

The defined cone dimensions establish the mating geometry used for reference connector testing. Selection should take account of the connector design, dimensional requirements and applicable test procedure.

Role of the Cone Reference Connector

In connector testing, the mating component must have defined dimensions so that the test is not affected by uncontrolled variations in the opposing connector.

The KP-8637F4 addresses this requirement by providing a precision-defined conical interface.

Reference Mating Geometry

The connector features a 6:100 taper with specified cone dimensions and tolerances. This geometry provides a reference mating surface for the blood socket connector under test.

Consistent Connector Engagement

A reference connector helps establish a defined mating condition when specimens are tested using the same geometry and appropriate laboratory procedure.

Integration with Test Equipment

The KP-8637F4 can serve as the mating component within a compatible connector test fixture. The required force, pressure or other test conditions are applied and measured by the appropriate external equipment.

The reference connector itself does not measure pressure, leakage, axial force or torque.

How the Reference Connector Is Used

The KP-8637F4 functions as a reference mating component within a connector test setup.

A typical laboratory arrangement involves selecting the appropriate reference connector geometry, securing the reference component in a compatible fixture and mating it with the blood socket connector under test.

The laboratory then carries out the applicable test procedure using the required external equipment and controlled test conditions.

The reference connector contributes the defined mechanical mating interface. Other parts of the test arrangement may provide pressure regulation, force application, measurement or observation, depending on the test being performed.

For reliable test results, the mating alignment, fixture arrangement and connector preparation should correspond to the applicable procedure.

ISO 8637-2 Standard and Test Application

ISO 8637-2 specifies requirements for disposable extracorporeal blood and fluid circuits and associated accessories used with haemodialysis equipment.

These systems are used in extracorporeal blood treatment therapies, including haemodialysis, haemodiafiltration and haemofiltration. Connections between blood circuit components and their intended mating interfaces are subject to applicable dimensional and functional requirements.

The KP-8637F4 provides a defined conical reference interface for blood socket connector testing associated with ISO 8637-2.

A complete connector conformity assessment may require additional procedures to evaluate leakage, mechanical separation or other connection characteristics. The reference connector forms part of the relevant test arrangement and does not replace the equipment needed to apply or measure those conditions.

Typical Laboratory Applications

Blood Circuit Connector Development Reference mating interface for evaluating the connection geometry and compatibility of blood socket connector designs.
Medical Device Testing Laboratories Integration into connector test arrangements requiring defined ISO 8637-2 conical reference geometry.
Manufacturing Quality Verification Supporting controlled connector evaluation during product validation and quality-assurance activities.
Testing Fixture Development Reference mating component for designing or adapting compatible blood socket connector testing fixtures.

Compliance & Regulatory Assurance

The KP-8637F4 Cone Reference Connector is designed for blood socket connector testing associated with ISO 8637-2, incorporating defined 6:100 conical geometry, dimensional tolerances and precision-machined 440C stainless steel construction.

The reference connector supports standardized mating conditions within the applicable test arrangement. Complete conformity assessment of the finished connector depends on the relevant standard edition, required test procedures and additional testing equipment.

FAQ

What is the KP-8637F4 used for?
The KP-8637F4 provides a defined conical mating interface for testing blood socket connectors associated with ISO 8637-2. It is intended for use as a reference component within an appropriate connector test arrangement.
Can the KP-8637F4 be used without a testing instrument?
The KP-8637F4 is a mechanical reference connector, not a complete testing instrument. Functional testing requires the applicable fixture, equipment and measurement procedure. Its standalone use does not establish the functional conformity of a connector.
Can the KP-8637F4 be used for connector leakage testing?
It may be incorporated into a connector leakage test arrangement where its reference geometry is appropriate to the specified procedure. The reference connector itself does not generate pressure or measure leakage. Compatibility with the required test method should be established before ordering.
What is the taper ratio of the reference connector?
The KP-8637F4 has a 6:100 taper ratio with defined dimensional limits. The mating geometry also includes specified cone diameters, reference lengths and an edge-radius limit.
Does the reference connector measure insertion or separation force?
No. The KP-8637F4 does not contain a force-measuring system. Where connector testing requires a controlled axial load or separation-force measurement, the appropriate external test equipment must be used.
How do I confirm compatibility with my blood socket connector?
Check the applicable ISO 8637-2 edition, the connector's mating geometry and the reference dimensions required by the test procedure. A connector drawing can be provided for technical review before quotation.
Can the KP-8637F4 replace the KP-8637F3 Conical Gauge?
No. The two products have different reference geometries and intended functions. KP-8637F3 is used for dimensional gauging, while KP-8637F4 serves as a reference mating component for the applicable connector test arrangement.
Can the KP-8637F4 be integrated into an existing test fixture?
Integration is possible where the fixture can accommodate the connector geometry and required mounting arrangement. The fixture interface, alignment and intended test method should be reviewed before selecting the reference connector.
Is the KP-8637F4 suitable for ISO 80369-7 Luer connector testing?
The KP-8637F4 is intended for ISO 8637-2 blood socket connector testing and should not automatically be treated as an ISO 80369-7 Luer reference connector. The mating geometry and applicable test requirements differ.
