45、95 percent hydrogen B = Grade B - 99.99 percent hydrogen C = Grade C - 99.999 percent hydrogen Federal specification number 1The volume of the cylinder may be modified for ease of procurement and is not otherwise limited. The volume codes listed above are not all inclusive and are provided only for
46、example. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-BB-H-886E 7 6.4 Basis of purchase. The basis of purchase should be the cubic foot, based upon normal atmospheric conditions. Hydrogen is commercially available in cylinders of various rated cap
47、acities, with capacities of approximately 200 and 300 cubic feet being common. The quantity in cubic feet for each cylinder size is provided in the characteristics data of the applicable stock number. Normally, hydrogen cylinders will be filled to the following standard conditions: 1800, 2000, 2265,
48、 or 2400 pounds per square inch gauge (psig) at 70 F (21.1 C). In cases where the only cylinder available is rated for a higher pressure than requested, Department of Transportation regulations allow for cylinders to be filled to less than the marked service pressure. Also, cylinders specially quali
49、fied under 49 CFR to bear the plus (+) mark, have been approved for special filling limits up to 10 percent above the marked service pressure. 6.5 Subject term (key word) listing.
