The performance requirements apply to couplings made from carbon steel. The use of any combination of other materials and the related performance requirements shall be agreed between the customer and the manufacturer.
The maximum working pressure shall be verified by a pressure impulse test conducted in accordance with ISO 7241-2 for 200 000 cycles in the uncoupled condition and 500 000 cycles in the coupled condition. The type, size, and tolerance class of the thread used on the counterpart of the coupling should be recorded in the test report.
The minimum burst pressure shall be verified in the coupled and uncoupled conditions by testingin accordance with ISO 7241-2.
The pressure drop at rated flow rate, fluid loss, and surge flow rate capability shall be verified by testing in accordance with ISO 7241-2.
Couplings shall be designed to be connected at 33 % of the maximum working pressure, which is considered to be the residual working pressure in one coupling half. Couplings shall pass the endurance test specified in ISO 7241-2 by connecting 100 times with an internal pressure of 33 % of the maximum working pressure without any damage to the coupling’ s functionality.
During coupling and uncoupling, torsion of hydraulic hoses shall be avoided. The use of a suitable tool is recommended to provide proper assembly; for example, a wrench or grip can be used to fix one half of the coupling during coupling and uncoupling.BS ISO 14541 pdf download.
