3、0, 1995 COMMERCIAL ITEM DESCRIPTION BATTERBOARD, SYNTHETIC The General Services Administration has authorized the use of this commercial item description, for all federal agencies. 1. SCOPE. This Commercial Item Description (CID) describes the requirements of synthetic batterboard panels including p

4、lanks made from Ultra High Molecular Weight Polyethylene (UHMWPE) which is partially backed up with an elastomeric material for improved impact resistance. 1.2 Intended use. The batterboard, a protective panel, is required in the well decks of U.S. Navy ships that carry boats, landing craft, and oth

5、er equipment. Adverse sea conditions and the ability to control boats and landing craft within the well area, when open to the sea, require the use of batterboards to provide some form of protection to both the ship and the service craft. 2. CLASSIFICATION. Synthetic batterboards shall conform to th

6、e following types, sizes, and weight ranges: 2.1 Types. Unless otherwise specified (see 7.1 and 7.2.1), synthetic batterboards shall be provided in either standard type 3.5-inch thick panels (preferred 2-ply for new ship construction and replacement of 3-ply construction or 3-ply construction for li

7、ke replacements) or lightweight type 2.5-inch thick (for areas of well deck experiencing low impact forces) and in types and sizes as specified on installation drawings. Figures 1, 2, and 3 show the 2- and 3-ply configurations. FIGURE 1. Two-ply panel configuration including planks. Provided by IHSN

NOTES:

29、1. Plank weights shown in tables are estimated. Actual panel weights may vary. 3. SALIENT CHARACTERISTICS. 3.1 Material. Synthetic batterboard panels shall consist of UHMWPE facing the well deck and shall be backed up by an energy absorbing elastomer material. The UHMWPE material shall use a base vi

30、rgin resin made in accordance with ASTM D4020 and have a nominal molecular weight of 3.1 by 106 or greater. The UHMWPE and elastomer materials shall be modified using additives and fillers as necessary to achieve the required properties specified herein. 3.2 Material properties. The synthetic batter

31、board material(s) shall meet all of the requirements specified herein when tested over a normal operating temperature range of -20 to +125 F (-28.9 to +51.7 C). The UHMWPE surface facing into the well deck shall also be capable of withstanding brief excursions, not to exceed 2.0 minutes, at a surfac

32、e temperature of 220 F (104.4 C). Where applicable, test specimens shall be the full panel thickness. 3.2.1 Flame spread. The test specimens shall be prepared and tested in accordance with ASTM E162 and shall not exceed a 25 ls (flame spread index) value. The test specimens shall be placed in the te

33、st fixture so that the impact surface faces the flame source. The test specimen shall exhibit no dripping or puddling during the test and shall be self-extinguishing after the flame source has been removed. Surface coatings or supplementary materials such as long strand fiberglass shall not be used

34、to retard burning of the synthetic batterboard panel. 3.2.2 Smoke density. The test specimen shall be evaluated to determine the relative amount of smoke produced by burning or decomposition in accordance with ASTM E662. The test specimens shall be placed in the test fixture so that the impact surfa

35、ce faces the flame source. The smoke generated during the flaming and nonflaming modes shall not exceed 450 Dm (maximum specific optical density). 3.2.3 Impact resistance. UHMWPE test specimens shall be prepared and tested as described in ASTM D256, Method A (except that the Izod specimens shall be

36、unnotched). These unnotched test specimens shall be capable of absorbing an Izod condition of 45 inch-pounds/inch (202 Joules/meter). No breakage or cracking of the test specimen is permitted under any circumstances. 3.2.4 Coefficient of friction. The test specimen shall be prepared and tested in ac

37、cordance with ASTM D1894. The dynamic coefficient of friction of the UHMWPE surface facing into the well deck shall not exceed a 0.2 value against steel (dry). 3.2.5 Resilience. The test specimen shall be prepared and tested in accordance with ASTM D2632. The energy absorbing elastomer shall be form

38、ulated so that the resilience does not exceed a 25 percent rebound value. 3.2.6 Paintability. The low-coefficient of friction slippery surface facing into the well deck of the batterboard panels or planks shall be capable of being painted for marking and coding. Paints meeting the requirements of th

39、e Master Painters Institute, MPI #9, Alkyd, Exterior, (MPI Gloss Level 6) and MPI # 94, Alkyd, Exterior, Semi-Gloss, (MPI Gloss Level 5) shall be used to ensure compliance. 3.2.7 Color. The color of the UHWMPE material shall be black unless otherwise specified (see 7.1). Provided by IHSNot for Resal

40、eNo reproduction or networking permitted without license from IHS-,-,-A-A-59001A(SH) 7 3.3 Test requirements. The synthetic batterboard panels shall meet all of the requirements specified herein when tested in accordance with the standard tests identified in 3.2. The test specimens for 3.2 shall be

41、sized to consist of the complete panel thickness (e.g., 2-ply, 3-ply, or lightweight construction panels or 2-ply batterboard planks). 3.4 Construction. The synthetic batterboard panel shall consist of a sandwich-type construction, whereby layers of UHMWPE and energy absorbing elastomer materials ar

42、e combined together into a single panel, whether it is the 2-ply, 3-ply, or lightweight design. For direct attachment to the bulkhead steel installations, at least 50 percent of the backside of the UHMWPE layer shall be backed by an elastomer which is 1 inches (38.1 millimeters) thick for 2-ply, 1 i

43、nch (25.4 millimeters) thick for 3-ply, and 0.5 inch (12.7 millimeters) thick for lightweight designs, or as shown on the applicable ship class installation drawings. The panel shall include approximately a 6- by 6-inch (152.4- by 152.4-millimeter) square of elastomer material centered at each faste

44、ner location and a minimum 3-inch (76.2-millimeter) to a maximum of 6-inch (152.4-millimeter) wide strips of elastomer material around the complete panel perimeter. The remainder of the 50 percent elastomer material shall be uniformly distributed over the remaining panel area using a strip pattern w

45、ith the strips not less than 3 inches (76.2 millimeters) or more than 6inches (152.4 millimeters) in width unless otherwise specified on installation drawings. The strips are to be attached by the manufacturer using corrosion-resistant steel, Grades 304 or 316, fastener hardware so that strips can b

46、e repositioned in field if necessary. Refer to 611-6917107 for further guidance on the construction of the various batterboard panels. 3.5 Frame mounting. For installations where batterboard panels are mounted to frames, and including plank-type construction panels, the complete surface of the panel

47、 that comes into contact with the frame shall have a layer of energy absorbing elastomer material as part of its overall thickness. This shall supersede meeting the 50 percent requirement. In this case, the details on the ship class drawings need to be followed in manufacturing the batterboard panel

48、s. 3.6 Panel size and weight. The synthetic batterboard panels shall be of the required type (see 7.1) with the weights and dimensions as specified (see 2.1 through 2.3) or planks as specified (see 2.4). Production tolerances on the actual overall length and width of the synthetic batterboard panel or planks shall be not greater than 0.125 inch (3.2 millimeters). Production tolerance of the batterboard panel or plank thickness shall not be greater than 0.125 inch (3.2 millimeters). 3.7 Installat
