Flex/impulse and impulse, so-called service life test
These tests are performed in one of HDTC's large rigs where up to twelve hoses can be tested simultaneously. These tests simulate an accelerated service life of a hose assembly. We perform tests in accordance with ISO 6803 (impulse test) and ISO 8032 (flex/impulse test) or according to the customer's unique requirements.
A standard test includes between 150,000 and 1,000,000 impulse cycles with a pressure up to 730 bar and an oil temperature up to 150 °C.The test procedure is the toughest possible, designed to simulate way more than just normal operation.
Individual hose and pipe assemblies that require a certificate, are test pressured to a maximum of twice the working pressure for up to 60 seconds before delivered to the customer. This is a smart way to test, as the service life is not affected and even the slightest error or defect can be detected immediately. The same equipment is also used to validate the specified burst pressure for our hoses.
Leakage and bursting test
A leakage and bursting test is performed to ensure that the connection on a hose with mounted coupling and sleeve holds tight and that the connection remains at at least the specified bursting pressure. The test equipment can also be used to measure change in length of hose under pressure.
Hydroscand can perform tests up to 4,000 bar and complies with standard EN ISO 1402.
