After assembly verify that the pipe does not touch metal bodies: the vibrations caused by the running vehicle could damage the pipe. The pipe must be protected with guards at specially high temperature points. It must be provided that the pipe does not touch guards at assembly. Check that pipes are not stretched between one clamping point and another; they must slightly slackened to make up for the greater changes in lengths in comparison with steel pipes, due to changes in tem-perature. Any crossing of metal walls must be protected with non –abrasive material bushings.5REQUIREMENTS FOR PRODUCT QUALIFICATIONSubmit the components to the tests required in the relevant “T echnical Sheet ” as reported in point 6 or in additional information for each “T echnical Sheet ”.Limits of acceptability are reported on the respective “Technical Sheet ” for each specific type.6TEST PROCEDURES 6.1MaterialVerify that the material complies with requirements and shows all its properties in conformance with the information given in the IVECO STD. relating to these materials.6.2Bursting testFasten the part, previously filled with suitable fluid, to the testing machine by means of its own fittings or the fastening clamps shown in IVECO STD. 11–4543.If a heat bursting test is required, after having assembled the part, condition it for 2 hours at the temperature shown on the “T echnical Sheet ” before carrying out the test.Increase pressure until bursting is acheived, at a rate according to the following ratio:Pressure increment +P (burst pressure )3(bar ńmin )If the bursting test is to be performed after ageing, the tested parts will have to be completely filled with the test fluid.18–0400Page 7/11Date05.09.2005IVECO S tanda rdPUBLISHED BY SATIZ - NORMAZIONE6.2.1Minimum reference values for this test must be those specified in SAE Standard J517 – June 1994– i.e.: 4 times max. operating pressure (unless otherwise specified on drawing or on special product Technical Sheet).6.3Expansion of diameterPrepare the part and attach it to the special equipment at the temperature shown on the “T echnical Sheet ” for at least 60 min. Measure the outside diameter.Increase internal pressure up to the test level according to ratio in point 6.2. Measure the outside diameter and calculate the percentage variation.6.4Declining clamping torque (sleeves)Fasten the sleeve onto a metal spindle whose dimensions are according to drawing by means of the same type of clamps used on the motor –vehicle.Close the clamp, applying the clamping torque shown on drawing.Condition the assembly in an oven at the temperature indicated in the “T echnical Sheet ” for 70 hours.Remove from oven and after 60 minutes of conditioning at ambient temperature restore the original torque. Calculate the percentage decline.6.5Adhesion rubber / textile reinforcementObtain from the testbed part some specimens at least 10 mm wide and 80 mm long.Start to detach the reinforcement from the rubber for the complete width of the specimen, to allow attachment to the heads of the tensile stress machine.Submit the specimen to tensile stress at a speed of 450 mm/min. Record the load variation.The adhesion value is given by the average loads shown between the 11th and 20th peak of the recording. No value must range below 50% of the average calculated.6.6Pulsating pressure fatigue testAssemble the pipe, as it usually would be on the motor –vehicle, by means of the connectors or fas-tening clamps normally used, on special equipment with a thermal conditioning chamber.Let the fluid in use run into the pipe or sleeves setting the initial temperature in the chamber in accor-dance with the information on the “Technical Sheet ”.The pressure of the fluid must vary sinusoidally within the values reported on the said “T echnical Sheet ” at a frequency between 0.1 – 0.5 Hz.When the test is over check if leaks or cracks have occurred.6.7Pipe fitting withdrawing load (pipes)Fasten the parts by means of their own pipe fittings to the heads of a dynamometer. Subject the parts to tensile stress at a speed of 50 mm/min. The actual breaking load of the parts or the withdraw-ing load of pipe fittings is calculated using the following ratio:T w KP Awhere:–T = tensile stress of pipe fittings (daN);–K = factor of safety = 3;–P = working pressure of pipe (daN/cm 2);–A = surface of internal section of pipe (cm 2).18–0400Page 8/11Date05.09.2005IVECO S tanda rdPUBLISHED BY SATIZ - NORMAZIONE6.8Axial and side stiffness (straight sleeves and sleeves with bellows outline)6.8.1Measuring axial load –deformation curveFasten the sleeve by means of the proper clamps specified in IVECO STD. 11–4543, on unions complying with IVECO STD. 10–4302 and then extend/compress by means of a dynamometer and with 20 mm/min load application speed.Measure load –deformation curve and check that it falls within the limits specified on drawing.6.8.2Measuring side load –deformation curveFasten sleeve by means of the proper clamps specified in IVECO STD. 11–4543 and union comply-ing with IVECO STD. 10–4302, then position it on the square device allowing load application on one end.On the other end apply load by means of dynamometer with 20 mm/min application speed.Measure load –deformation curve and check that it falls within the limits specified on drawing.6.9Axial jolting fatigue test (straight sleeves and sleeves with bellows outline)Fasten the sleeve, by means of the clamps indicated in IVECO STD. 11–4543, to a support integral with the mounting face of equipment suitable for imposing strain fatigue tests.
