A so-called rolling test of PTFE hoses in U shape can be carried out on it, whereby they must withstand approx. 100,000 test cycles in continuous operation under operating pressure. This is a requirement for obtaining the hose standard DIN EN 16643.
By implementing type testing, Markert is living up to its responsibility as a manufacturer, and ensuring the qualitative and quantitative suitability of a hose before it is incorporated into the company’s range of products. Furthermore, the “Rolling U” test is repeated regularly to ensure that the high standards are met on a permanent basis.
