DIN | 2021-10 | 16 |
This International Standard specifies two methods for measuring the stiffness and one method for determination of the flexibility of rubber or plastic hoses or tubing when they are bent to a specific radius at sub-ambient temperatures. Method A is suitable for non-collapsible hose with a nominal bore up to and including 25 mm. The method provides a means of measuring the stiffness of the hose when the temperature is reduced from a standard laboratory temperature. Method B is suitable for hoses and tubing up to 100 mm and provides a means of assessing the flexibility of the hose when bent around a mandrel at a specified sub-ambient temperature. It may also be used as a routine quality control test Method C is suitable for hose of 100 mm and above. The method provides a means of measuring the stiffness of the hose at sub ambient temperatures. This method is only suitable for hoses that have a helical wire.
