18 Drop Test
18.1 An emergency breakaway fitting of the reconnectable type shall conform to the requirements of the Electrical•Continuity Test, Section 12, the External Leakage Test. Section 13. the Seat Leakage Test.
Section 14, and the Pull Test, Section 20, before and after having been subjected to the COnCliOning specified in 18.2 and 18,3.
18.2 Two samples 01 an as-received breakaway fittings are to be tested. The fittings are to be separated and the outlet ends are to be attached to a 10 foot (3.1 m) length of 314 inch (19.1 mm) hose. A vapor recovery fitting is to be attached to a 10 foot (3.1 m) length of vapor recovery hose. Connections are to be made using the torque values Indicated in Table 7.2.
18.3 The assembly is then pressurized to the maximum design pressure for each drop, but not less than 50 psi (340 kPa). For vapor recovery products, only the liquid path is to be pressurized. The fitting is to be dropped a total often times from a height of 8 feet (2.4 m) onto a concrete floor in a manner that tends to cause the fitting ends to strike the floor first. Following the ten drops, the tests in Sections 12, 13, 14.
and 20 are to be repeated.
Exception No. 1: An emergency breakaway fitttrrg for use between the hose nozzle valve and hose assembly only, shall have both ends dropped from 4 feet (1.22 m) onto a concrete floor in a manner that tends to cause the fitting ends 10 strike the floor frrst. The emergency breakaway tilting shall also be marked in accordance with 25.5.
Exception No. 2: An emergency breakaway fitting for connection to the dispenser outlet only or for connection to a whip hose ,nstalled to the dispenser outlet only. shall have the outlet end only dropped from 8 feet (3.1 m) onto a concrete floor in a manner that tends to cause the fiffing ends to strike the floor first. The emergency breakaway fitting shall also be marked with the flow direction and in accordance with 25.5.
19 Hydrostatic Strength Test
19.1 A device subjected to the Long Term Exposure Test, Section II shall withstand, without rupture or permanent distortion, a hydrostatic pressure of five times its maximum design pressure, but not less than 250 psi (1.72 MPa). Vapor confining components are subjected to a liquid or aerostatic pressure of 2.5 psig (17.2 kPa). External leakage is acceptable during this test provided the device complies with the requirements for leakage specified in the External Leakage Test, Section 13, following this test.
19.2 For non-reconnectable emergency breakaway fittings both halves of the fitting are to be tested separately after the pull test in accordance with the test sequence shown in 10.5.
19.3 Each test sample is to be connected to a source of hydrostatic pressure. A positive shutoff valve and a pressure indicating device, as described in 3.7, is to be installed in the pressure supply piping. The pressure gauge is to be installed between the shutoff valve and the sample under test.
19.4 The test pressure is to be slowty raised to the requwed test pressure and held for at least one minute.
20.1.2 A sample of the pipe-connecting fining subjected to the Long Term Exposure Test. Section 11, is to be subjected to this test. The sample is to be made up with pipe as described in 11.2,4.
20.1.3 The test sample is to be placed in a tensile testing machine and both ends are to be connected in such manner that the fitting or connector can be subjected to a direct longitudinal pull. The pull force is to be applied at a rate not in excess of 600 pounds (2700 N) per minute, and is to be increased until a pipe or tube pulls out of a pipe•connecting fitting.
20.2 Emergency breakaway fitting
20.2.1 An emergency breakaway filling, when tested in accordance with 20.2.2 — 20.2.5, shall separate upon application of a pull force not greater than the maximum rated separation force and not less than 100 pounds (445 N).
