NOTE Hose with a lower maximum change in length may be agreed between the purchaser and manufacturer. 6.1.2 Deformation under proof pressure A proof pressure hold test shall be carried out on three hose lengths each of 1 m in accordance with EN ISO 1402. The proof pressure shall be as given in table 2 and on examination during the test, the test pieces shall not show any evidence of leakage, cracking, abrupt distortion or other signs of failure. 6.1.3 Minimum burst pressure !A burst pressure test shall be carried out in accordance with EN ISO 1402 on the three test pieces used for the deformation under proof pressure test. NOTE It is not necessary to increase the pressure above the minimum burst value to burst the hose. It is sufficient to increase the pressure to the required minimum burst pressure stated in Table 2 in order to pass this test requirement.
This should be stated in the Test Report."
Each of the test pieces shall not burst at a pressure less than that given in Table 2. 6.1.4 Kink pressure When tested in accordance with annex A, the test piece shall neither burst nor show any visible signs of defect before or after pressurizing at 1,5 MPa for category I hoses and at 4,0 MPa for category II hoses. 6.2 Adhesion When tested in accordance with EN 28033 the adhesion between all components shall be not less than 1,5 kN/m for type A hoses, 1,0 kN/m for type B hoses and 2,0 kN/m for type C. Dependent on the construction of the hose, the test piece in all cases shall be decided by the test laboratory in accordance with EN 28033. 6.3 Accelerated ageing When tested in accordance with annex B, the three test pieces subjected to the burst pressure test shall conform to the requirements of 6.1.3.
The mean of the burst pressure test results shall not decrease by more than 25 % from the initial mean burst value determined from the results obtained in 6.1.3. The resultant adhesion of the fourth test piece shall be in accordance with the requirements of 6.2. NOTE There is no limitation on the increase in the values of these properties.
EN 1947:2002+A1:2007 (E) 11
6.4 Abrasion resistance NOTE Abrasion tests are specific to different hose constructions and/or materials.
Two procedures with different values are therefore specified here to avoid unfair discrimination.
In addition, it is important to note that the requirements, revolutions as given in table 5 and double strokes as given in Table 6, cannot be correlated. 6.4.1 Abrasion resistance of class 5 and class 6 hoses When tested in accordance with annex C and using the number of revolutions given in Table 5, at least four of the five test pieces shall not burst on being subjected to the normal working pressure given in Table 2.
