11.4.3 For casting impregnation materials, the sample shall not show evidence of porosity leakage during or after the Iluid exposure duration.
11.4.4 For internal nonmetallic parts. there shall be no visible evidence of this material in the drained test
12 Electrical-Continuity Test
12.1 General
12.1.1 Breakaway devices and swivel connectors shall be tested using the test method as indicated in 12.2 or the alternate test method in 12.3.
12.1.2 For assemblies with more than one swivel connector, continuity shall be measured across the entire assembly while rotating each swivel connector independently.
12.2 Electrical continuity measurement
12.2.1 The electrical resistance across a device shall not exceed 0.5 megohms.
12,2.2 The electncal continuity determination is to be made using a resistance indicating instrument. When a swivel is being tested, the swivel shall be rotated 360 degrees with the leads of the instrument are attached, and the highest reading obtained is to be considered the resistance of the swivel connector.
12.3 Electrical continuity alternate method
12.3.1 Breakaway couplings and swivel connectors shall not have an electrical resistance greater than 5800 ohms per inch (2280 ohms per centimeter) when tested in accordance with 12.3.2.
12.3.2 The electrical resistance is to be measured by means of an appropriate ohmmeter. When a swivel is being tested, the swivel shall be rotated 360 degrees while the leads of the ohmmeter are attached, and the highest reading obtained is to be considered the resistance of the swivel connector.
13 External Leakage Test
13.1 A device shall not leak when subjected to a hydrostatic source of pressure of 1-1/2 times its maximum design pressure, but not less than 75 psig (518 kPa), when tested as described below. Vapor confining components are subjected to a pressure of 314 psig.
13.2 The test sample is to be connected to a source of liquid or aerostatic pressure, and the opposite end is to be closed. A positive shutoff valve, and a pressure indicating device, as described in 3.8, is to be installed in the pressure supply piping. The pressure indicating device is to be installed between the shutoff valve and the test sample.
13.3 The sample pipe.connecting fining made up with piping or tubing in accordance with 11.2.4 is to be placed on honzontal supports 30 inches (760 mm) apart. The sample is then to be tested for leakage in this position. While the test sample is under the pressure of the test liquid, sufficient load is to be placed on the fitting to cause maximum deflection of the connected pipe as permitted by the fitting design. While in the deflected position, the fitting Is to be observed for leakage as described In 13.2.
14 Seat Leakage Test
14.1 An emergency breakaway fitting shall not leak past the seats when subecled to a hydrostatic or aerostatic test pressure starting at zero and increasing to 1.1)2 times its maximum design pressure, but not less than 75 psig (518 kPa), when tested as described below. This test is only conducted on the liquid path for vapor recovery products.
14.2 Both halves of an uncoupled sample of the emergency breakaway fitting are to be connected to a hydrostatic or aerostatic source of pressure. A positive shutoff valve, and a pressure indicating devce, as described in 3.7, is to be installed in the pressure supply piping. The pressure indicating device is to be installed between the shutoff valve and the test sample. The pressure is to be increased gradually from zero and then maintained at 1-1/2 times the maximum design pressure. but not less than 75 psg (518 kPa). The test is then to be repeated at a pressure of 1/4 psi (1.7 kPa).
15 Operation Test
15.1 A swivel connector or emergency breakaway fitting which incorporates a swivel mechanism subected to the Long Term Exposure Test, Section 11, shall be subjected to 100,000 cycles of operation as described in 15.2 — 15.4.
15.2 Pnor to the test, the fluid confining portion of the sample is to be filled with kerosene or Soltrol 170. For the duration of the test, the liquid is to be under a pressure of 50 psig (340 kPa).
15.3 The operating mechanism Is to be arranged so that, during each cycle of operation, each swivel joint is rotated through an arc of 180 + 10 degrees at a rate not in excess of 30 cycles per minute. If the connector is constructed with more than one swivel joint, and it is not feasible to operate all joints simultaneously, then it is possible for any one joint to be operated separately. Rotation of the joint 180 +10 degrees and men back to the initial position is considered 1 cycle of operation.
