ISO 18250-3 Figure C.3 Reference Connector

Role of the Figure C.3 Reference Connector in Leakage and Unscrewing Tests

The ISO 18250-3 Figure C.3 Reference Connector is used as a defined reference connector in test configurations involving cross-port reservoir connectors. During testing, the customer’s sample connector is assembled with the Figure C.3 reference connector so that the connection interface can be evaluated under the required leakage, stress cracking or unscrewing-related conditions.

This product should not be treated as a general dimensional gauge only. It is part of a functional connector test setup where the mating condition, sealing performance and controlled disconnection behavior may affect the final evaluation result. The correct test fixture and connection method should therefore be confirmed before quotation.

KINGPO supplies the Figure C.3 reference connector as a precision-machined stainless steel component for ISO 18250-3 related connector testing. Depending on the selected test item, it may be used together with leakage test equipment, stress cracking test preparation accessories or unscrewing-related fixtures.

What This ISO 18250-3 Figure C.3 Connector Is Used For

The Figure C.3 reference connector is mainly used for test setups where a cross-port reservoir connector needs to be evaluated under leakage or unscrewing-related performance requirements. It provides a defined reference interface for checking whether the sample connector can maintain the required connection performance during laboratory verification.

Typical applications include:

• Cross-port reservoir connector verification
• Positive pressure liquid leakage test setup
• Subatmospheric pressure air leakage test setup
• Stress cracking related test preparation
• Resistance to separation from unscrewing
• Disconnection by unscrewing test setup
• Enteral reservoir connector product validation
• Laboratory quality control and pre-compliance checking

The exact test method, medium, pressure condition, unscrewing direction and fixture arrangement should be confirmed according to the applicable ISO 18250-3 test requirement.

Leakage and Unscrewing Test Setup Notes

Figure C.3 is normally used as part of a connector performance test setup rather than as a standalone test instrument. For leakage-related testing, the pressure source, test medium, sealing condition and connection method should be reviewed together with the sample structure.

For unscrewing-related tests, the fixture arrangement is important because the result may be affected by mating alignment, applied rotation, holding method and connector condition before testing. If the project involves both leakage and disconnection evaluation, the customer should confirm whether one reference connector is sufficient or whether additional accessories are required for different test steps.

Before quotation, it is helpful to confirm:

• Required ISO 18250-3 figure number
• Sample connector structure
• Intended test item
• Leakage medium and pressure condition, if applicable
• Unscrewing or disconnection test requirement
• Whether only the reference connector is needed
• Whether matching leakage or fixture equipment is required
• Documentation requirements for inspection or material information

Configuration and Documentation Notes

The Figure C.3 reference connector is made from stainless steel and intended for repeated laboratory handling when properly used, cleaned and stored. Because ISO 18250-3 connector testing may involve different leakage, stress cracking and unscrewing-related methods, the connector should be selected together with the required test item and sample structure.

Documentation requirements can be discussed before order. Depending on the project scope, dimensional inspection records, material information or other supporting documents may be prepared according to the agreed supply requirements.
