3、EDING A-A-52163A May 29, 1996 COMMERCIAL ITEM DESCRIPTION LADDERS, VEHICLE-BOARDING The General Services Administration has authorized the use of this Commercial Item Description (CID) for all federal agencies. 1. SCOPE. This CID covers nine different types of portable, metal, step-ladders (hereinaf
4、ter referred to as ladders) for use by personnel in boarding vehicles. 2. SALIENT CHARACTERISTICS 2.1 Materials. The materials used for the ladders shall be either aluminum or steel as specified. However, the specific material compositions of the aluminum and steel shall be in accordance with the ac
5、ceptable commercial material specifications for metal ladders. Component corrosion protection shall be equal to or exceed that provided by hot dip galvanized 1020 steel with coating thickness in accordance with ASTM A123/A123M. 2.2 Design and construction. The ladders shall conform to the physical a
6、nd dimensional requirements specified in figures 1 thru 9. The ladders shall also conform to the applicable requirements of ANSI A14.2 for portable metal ladders. When applicable, drawings and dimensions of ladder components that are needed, but not shown in figures 1 thru 9, shall be provided by th
7、e procuring activity (see 6.2). The ladders shall conform to the applicable requirements of ANSI A14.2. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-A-A-52163B 2 2.2.2 Dimensional tolerances. Unless otherwise specified, the dimensions specified in
8、 figures 1 thru 9 shall have the following tolerances: a. For dimensions less than or equal to 10 mm, tolerances shall be 0.4 mm and 1 degree (). b. For dimensions greater than 10 mm and less than or equal to 100 mm, tolerances shall be 0.8 mm and 1. c. For dimensions greater than 100 mm, tolerances
9、 shall be 2 mm and 1. 2.3 Weight. The total weight of any ladder shall not exceed 18 kilograms (kg) 40 pounds (lb). 2.4 Load. Each step of every ladder shall be capable of withstanding a 360 kg (800 lb) load without damage or permanent set to any of the ladder parts. 2.5 Welding. Welding procedures
10、shall be performed in accordance with the manufacturers standards for welds. In no event shall processes such as peening and plugging be used for reclaiming any part of the ladder without authorization from the procuring activity. Warpage shall be limited to 6.4 millimeters (mm) 0.25 inches (in) out
11、 of plane. There shall be no lack of fusion which causes failure. 2.5.1 Welded surfaces. All welded parts shall be clean and free of dirt, sand, scale, and other extraneous materials. The welded surfaces shall be free of burrs, cracks, and inclusions. All sharp corners shall be rounded or beveled, e
12、xcept for those on the non-skid step surfaces. 2.6 Non-skid surfaces. All steps shall be constructed of material which has been formed in a manner to provide for a permanent non-skid surface. 2.7 Coatings. The ladders shall be cleaned, pretreated, primed, and painted in accordance with the accepted
13、commercial standard practice. Unless otherwise specified (see 6.2), the base topcoat color shall be green 383, chip number 34094 of FED-STD-595. If CARC paint or camouflage patterns are required, it will be specified in the contract or order (see 6.2). 2.8 Warning labels. Ladders shall have warning
14、labels that contain “Danger” markings in accordance with appendix A of ANSI 14.2, warning personnel that the ladder will conduct electricity. The label design and color shall conform to this standard. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-A
