14.6 For vapor recovery fittings, the inner liquid line 0 rings in me female connection end shall be subjected to 100,000 cycles of operation using the test method described in 14,2. A vapor recovery hose assembly is to be connected to the female connection end, During the cycling, the fitting is fixed and the inner liquid line of the hose assembly is to be rotated through an arc of 180 + 10 degrees and back to the initial position for each cycle of operation.
15 Endurance Test
15.1 An emergency breakaway titling of the reconnectable type shall be capable of conforming to the requirements of the Electrical-Continuity Test. Section 11, the External Leakage Test, Section 12, the Seat
Leakage Test, Section 13, and the Pull Test, 19.2.1 — 19.2.5. before and after having been sublected to 100 cycles of operation as described below.
15.2 The breakaway fitting shall be connected to a source of liquid or aerostatic pressure (as specified by the manufacturer) and pressurized to 50 psig (340 kPa) for couplings intended to handle petroleum products and 350 psig (2414 kPa) for fittings intended to hance anhydrous ammonia or LP-Gas. For vapor recovery products, only the liquid path is to be pressurized. One end of the sample is to be subjected to a pull force with enough energy to separate the sample. The pressure is to be reduced to zero and the two halves are then reassembled and the sample pressurized. This is determined to be 1 cycle of operation.
16 Abuse Test
16.1 A hose swivel or emergency breakaway fitting shall not crack, rupture, or show other evidence of failure, and shall comply with the requirements of the Electrical-Continuity Test, Section 11. and the External Leakage Test, Section 12, before and after the Abuse Test specified in 16.2 and 16.3.
16.2 The remaining two samples of the hose swivel or two samples of the emergency breakaway fittings subjected to the Electrical-Continuity Test. Section 11 and to the External Leakage Test. Section 12, are to be tested. Each hose swivel or emergency breakaway fining is to be attached to a 10-foot (3.0-rn) length of 3/4 inch (19.1 mm) hose. A service station-type hose nozzle valve or fuel transfer valve, as appropriate, is to be attached to each hose swivel or emergency breakaway fitting. A vapor recovery-type hose swivel or emergency breakaway fitting is to be attached to a 10-foot length of appropriate vapor recovery hose and to a representative vapor recovery hose nozzle valve. Connections are to be made using the torque values indicated In Table 8.2. The weight of the nozzle is to be as indicated in Table 16.1.
19.2.2 Three samples of emergency breakaway fittings are to be subjected to this test. The inlet and outlet of the emergency breakaway titling are to be attached to a hose, a hose and a swivel connector. or other fitting that is equivalent to these without hoses attached. The inlet fitting shall be held stationary and the longitudinal pull force is to be applied to the outlet fitting. The force required to separate the sample is to be measured. The samples are to be retested while pressurized to the maximum design pressure. For vapor recovery products, only the liquid path is to be pressurized.
19.2.3 If the breakaway mechanism uses nonmetallic parts, three additionaJ samples are to be tested following 24 hour conditioning at both minus 40°C (minus 40°F) and plus 52°C (plus 126°F).
19.2.4 It shall be determined that emergency breakaway fittings will separate upon applicahon of the rated pull force when the device is installed as intended In service and the pull force on the hose assembly is applied with the device in all operating positions.
19.2.5 In order to comply with the requirements in 19.2.4, all necessary pull tests are to be conducted on additional samples with the pull force on the outlet fitting applied from various directions likely to be encountered dunng use of the device.
20 Tests of Synthetic Rubber Parts
20.1 General
20.1.1 A synthetic rubber part in contact with one of the fluids indicated in Table 20.1 shall not show excessive volume change or loss of weight, when considered on the basis of its intended tunction, following immersion for 70 hours at a temperature of 23 ±2°C (73.4 ±3.6°F) in the specified test liquid. The weight loss test is not conducted with IRM 903 oil or with ASTM Reference Fuel A. See the Change-in-Volume Test. 20.2.1 and 20.2.2, and the Weight-Loss Test, 20.3.1 and 20.3.2.
