The Ruhr Cone Joint Performance Comprehensive Tester is a high-precision equipment designed specifically for testing the performance of small aperture connectors in medical devices (such as infusion sets, blood transfusion sets, infusion needles, catheters, etc.) and other industrial fields. Its comprehensive performance testing covers multiple key items to ensure the safety, reliability, and stability of connectors in practical use. The following are the key points for comprehensive performance testing of the tester:
1、 Testing items
Sealing performance test
Leakage test: Check the liquid sealing performance of the connection under pressurized conditions to ensure no leakage. The testing conditions are usually to apply a pressure of 300kPa-330kPa for 30-35 seconds, and there should be no liquid leakage marks on the joint, and no water droplets should form.
Leakage test: Evaluate the gas sealing performance of the connector under pressurized conditions. The testing conditions may include applying a pressure of 800kPa-880kPa for 15-20 seconds, with a leakage rate not exceeding 0.005Pam ³/s.
Mechanical performance testing
Separation force test: Evaluate the connection stability and ease of disassembly of the connector under external force. The testing conditions may include applying specific axial forces (such as sliding joint 23N-25N, screw joint 32N-35N) for 10-15 seconds, and the joint should not separate from the reference joint.
Unscrew torque test: Measure the torque required to unscrew the connector to ensure ease of operation and that it is not too tight or too loose. The testing conditions may include applying a torque of 0.198Nm-0.200N · m for 10-15 seconds, and the joint should remain connected and not loosen.
Anti slip wire test: Verify whether the connector experiences slippage after multiple uses to ensure long-term reliability.
Overload resistance test: Evaluate the overload resistance of connectors by applying overload torque. The testing conditions may include applying a torque of 15N · m-17N · m, and the joint should not exceed the thread or lug of the standard joint for 5-10 seconds.
Durability testing
Stress cracking test: By simulating long-term use, detect whether there will be stress cracking problems in the connectors. The testing conditions may include applying the stress specified in Appendix E of ISO80369-20:2015 and meeting the requirements of 6.1.6 of the standard.
Pressure attenuation leakage test: Under specific pressure, observe the pressure attenuation of the connecting piece and evaluate its sealing durability. The testing conditions may include applying a pressure of 300kPa-330kPa for 15-20 seconds and observing the pressure decay.
Usability testing
Easy assembly test: to examine whether the connectors are easy to assemble, reducing operational difficulty and errors.
2、 Testing principle
The testing principle of the Ruhr cone joint performance comprehensive tester is mainly based on the principles of mechanics and fluid mechanics. During the testing process, the tester applies physical quantities such as axial force, torque, and internal water pressure to the connecting components through the control system, simulating actual operating conditions. At the same time, the tester is equipped with high-precision sensors to monitor and record changes in various parameters in real time, such as pressure values, torque values, separation forces, etc. By comparing and analyzing these data, evaluate whether the performance of the connectors meets the standard requirements.
3、 Testing standards
These standards for the Ruhr cone joint performance comprehensive tester specify the dimensions, requirements, and testing methods of the connectors to ensure the accuracy and reliability of the test results.
4、 Technical characteristics of the tester
Integration of multiple testing functions: One device can perform all performance tests on Ruhr connectors, including liquid leakage, sub atmospheric air leakage, stress cracking, axial separation resistance, anti twist separation, overload resistance, etc.
Real time data display: The device is equipped with a colorful LCD touch screen, which displays test data in real time, and the testing process is transparent and intuitive.
Automatic judgment function: The test results can automatically determine whether they meet the standard requirements, reduce human operation errors, and improve testing efficiency.
Wide applicability: Suitable for performance testing of various Ruhr connector models and materials, meeting multiple standard requirements.
