18、Attatchmcnt i C*rn.3 4- scale Figure 1. Flow test set up 4.3.1 Flow rate test. Cold soak a GFA and full five gallon can (NSN 7240-01-337-5269) with JP-8 fuel (NSN 9130-01-031-5816) in an ambient temperature of -40F (+/- 2F) for a period no less than 4 hours. While maintaining a temperature of -40F (
19、+/- 2“F), put the GFA on the can and invert on a stand. Connect a 3/8 inch LD. fuel line to the GFA which shall empty into a collection bin. The outlet of the fuel line and height of the can shall be as shown in figure 1. The collection bin shall be placed on a digital scale (minimm resolution 0.05
20、kg) which shall be kept in surrounding temperatures within manufacturers recommendation for scale operation. Record the increase in the collection bin weight every 2 minutes until flow has stopped and record final weight of the fuel can. Compare the final weight of can to the weight of an empty can
21、and verify no more than 325 cc of fuel remain in the can. Verify the average flow rate from the can does not drop below 200 cc/min. 4.3.2 Sealing inspection. During test of 4.3.1, measure the torque required to provide a positive seal between the fuel can and GFA. At the end of the test measure the
22、torque required to remove the GFA. Torque shall be measured from the center of the GFA using an appropriate fixture and a calibrated torque wrench which measures in inch pounds. The torque wrench shall be kept at room temperature until immediately before measurements are taken. At no time shall the
23、torque exceed 120 in-lbs. Observe GFNcan assembly during flow test of 4.3.1. At no time shall there be any fuel leaks from the GFNfuel can assembly. With a GFA attached to a full 5- gallon fuel can, tip assembly on its side and verify there is no fuel leakage. t 4 Provided by IHSNot for ResaleNo rep
