16、ember 19871. GENERAL AND SCOPE1.1 General. The procedures established by MIL-STD-2189 are applicable.This section and the basic standard are to be considered as an integral singledocument.1.2 Scope. This standard establishes the method of calculating storeroomdata and provides the format for documen

17、ting the storeroom capacity table.2. REFERENCED DOCUMENTS2.1 Government documents.2.1.1 Standard. Unless otherwise specified, the following standard ofthe issue listed in that issue of the Department of Defense Index ofSpecifications and Standards (DoDISS) specified in the solicitation forms apart o

19、ficer.)2.2 Order of precedence. In the event of a conflict between the text ofthis standard and the references cited herein, the text of this standard shalltake precedence,3. DEFINITIONS3.1 Deck area. Deck area is the area in square meters or square feet ofthe storeroom compartment within the bounda

20、ries of the bulkheads and bottom ofshell plating. The area includes floor plates when these are installed.3.2 Packing factor. Packing factor is the ratio of the net stowagecapacity to the gross stowage capacity expressed as a percentage for theparticular stowage aid. This is a standard percentage ba

21、sed on studies andanalyses of past stowage aid utilization and is not to be modified or derivedduring the current calculations.3.3 Percent of storeroom utilization. Percent of storeroom utilizationis the ratio of the storeroom net volume to the storeroom gross volumeexpressed as a percentage.1Provid

22、ed by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-MIL-STD-2189(SH)SECTION 672-124 December 19873.4 Storeroom gross volume. Storeroom gross volume is the volume of thecompartment within the boundaries of the bulkheads and shell plating from thedeck or deck grat

23、ing to the stowage height. For refrigerated spaces it is thevolume within the boundaries of the bulkhead insulation and sheathing from thetop of the deck grating to the stowage height.3.5 Storeroom net volume. Storeroom net volume is the volume of thecompartment available for the material to be stow

24、ed. It equals the sum of thenet stowage capacity of each stowage aid within the space, including bulkstowage.3.6 Stowage aid. Stowage aid is any piece of equipment or fitting usedfor stowage, including bins, drawer shelf units, lockers, modular drawerstowage (MDS) cabinets, reels, shelving clips, ja

25、ckrods, battens or gratings.3.7 Gross stowage capacity. Gross stowage capacity is the total stowagevolume provided by the individual stowage aids.3.8 Net stowage capacity. Net stowage capacity is the usable stowagevolume provided by individual stowage aids.3.9 Stowage height. Stowage height is the c

26、lear height to which storesare to be stacked. For ship storerooms, it is defined as 6 feet 6 inches abovethe deck or deck gratings when provided. For refrigerated storerooms, it isdefined as 6 feet above the deck gratings. However, a minimum of 6 inches ofclear space is required above the bulk stowa

27、ge material. Hence, the stowageheight shall be reduced where necessary to meet the required clear space.4. GENERAL REQUIREMENTS4.1 Information factors. The following information shall be calculatedand provided for each storeroom:(a) Deck area.(b) Storeroom gross volume.(c) Net stowage capacity and n

28、umber of each type of stowage aidin the storeroom.(d) Storeroom net volume.(e) Percent of storeroom utilization.4.2 Computations. Computations shall be as follows:(a) Deck area. To find the deck area, multiply length times widthof deck within the boundaries of the storeroom bulkheads or thebottom of

29、 the shell plating. Measurements shall be as shown onfigure 1.(b) Storeroom gross volume. To find the storeroom gross volume,multiply the deck area times the stowage height of 6 feet forrefrigerated storerooms or 6 feet 6 inches for all otherstorerooms.2Provided by IHSNot for ResaleNo reproduction o

Net stowagecapacity for each type of stowage aid shall be calculated as follows:(a) Calculate the area of each unit of stowage.(1) Drawer, bin, shelf

31、 or rack. Multiply the clear widthtimes the clear depth. Measurements shall be as shown onfigure 2. Ignore partitions or dividers within drawerssince these are covered by the packing factor.(2) Bulk. Multiply the clear width within the boundaries ofbulkheads or battens times the clear depth. Bulk s

32、pacesshall be serviced by aisles according to the followingguidelines:a. Aisles shall have a clear width of 510 millimeters (mm)(24 inches). This requires an aisle width of 740 mm(29 inches) for telescopic tube battens, and 760 mm(30 inches) for portable battens.b. The aisle shall extend from the do

33、or to within 915 mm(36 inches) of the bulkhead opposite the door.c. No portion of the storeroom shall be more than 1.5meters (5 feet) from an aisle.d. Access shall be provided to all valves, damage controlfittings, operating gear, and manholes.(b) Calculate the gross stowage capacity of each unit of

34、 stowage bymultiplying the area determined above by the clear height.Height measurements shall be as shown on figure 3. Subtractany interferences such as pipes, vents, fans, light fixtures,and so forth which fall within the boundaries of the width,depth, or height measurements.(c) Determine the tota

35、l gross stowage capacity for each type ofstowage aid by adding the gross stowage capacity for each unitof the stowage aid within the storeroom.(d) Calculate the net stowage capacity of each type of stowage aidby multiplying the gross stowage capacity for each type ofstowage aid times the packing fac
