Product Information:
This product is suitable for testing the performance of breathing tubing used in anesthesia machines and ventilators,primarily referencing standard ISO 5367-2023. YY0461 Appendix E, Test for Increased Airflow Resistance in Bending. It is suitable for use by quality inspection agencies, medical device testing institutes, research institutions,medical device manufacturers, and other organizations.
Test Principle
Bending airflow resistance: Based on the completed airflow resistance test, suspend the tubing for the bending test on a small-diameter metal column. Tie a weight to the end of the tubing to ensure the breathing tubing is in contact with half the circumference of the metal column. Introduce air into the tubing at the manufacturer's rated flow rate and record the pressure increment.
