2-21. 2-22. 2-23. 2-24. Fuel sample containers used for sediment and water tests must be made of what construction? 1. Glass with a metal top 2. A nonmetallic material with glass linings 3. Glass with a nonmetallic top 4. Metal with glass linings Which of the following is NOT a requirement for the identification of a sample? 1. The location and name of the activity submitting the sample 2. The location of the point where the sample was taken 3. The sample classification 4. Test results A representative sampling of a large stock of packaged fuel revealed contamination sufficient to make the entire supply suspect. Further samples are taken, labeled, and sent to be tested. What were the first and subsequent samples taken? 1. A composite sample, and the others were routine samples 2. A routine sample, and the others were special samples 3. A routine sample, and the others were composite samples 4. A special sample, and the others were routine samples When visually inspecting a fuel sample, What should be the first thing you check? 1. The color of the fuel sample 2. The aroma of the fuel sample 3. The presence of water 4. The presence of sediment 2-25. How should you visually check a fuel sample for sediment? 1. Shake it vigorously to break loose any previously undetected emulsion 2. Whirl it rapidly so the fine particles will be thrown to the outside of the sample container 3. Place the sample container on a level surface and allow the sediment to collect on the sides of the container 4. Swirl it to form a vortex that will draw the sediment to the center-bottom of the container 2-26. If contamination is found in a fuel sample, another sample should be drawn in a new, clean container and the visual inspection repeated. 1. True 2. False 2-27. The contaminated fuel detector (CFD/CCFD) employs which of the following principles? 1. 2. 3. 4. Trapped solid contaminants increase the amount of light passing through the millipore filters Trapped solid contaminants decrease the amount of light passing through the millipore filters Solid contaminants increase the weight of the top millipore filter more than the color variation increases the weight of the bottom one The weight of the solid contaminants trapped between the millipore filters is equal to the amount of solid contaminants in the sample 10
