Low temperature flexural testing of rubber and plastic hoses

Rubber and plastic hose breathability test evaluates whether rubber or plastic hoses can maintain sufficient flexibility at temperatures below ambient.
Zhongke Testing Reliability Experiment Center has the capability to test the reliability performance of various rubber and plastic hoses, and provides professional low-temperature flexural testing services for rubber and plastic hoses.

According to the purpose, it is mainly divided into: threading hose, drainage hose, ventilation hose, shower hose, and wiring harness tube.
According to the material, it is mainly divided into: corrugated hose, rubber hose, and plastic hose.

Method A applies to non-collapsible hoses with a nominal inner diameter up to and including 25 mm. It is a measure of the increase in stiffness compared to flexure at standard laboratory temperatures.
Method B is a simpler qualitative method suitable for controlled testing and is suitable for hoses with a nominal inner diameter up to and including 100 mm.
