2.2.2 Feed wheel. The feed wheel shall be fabricated of free machining steel and shall be case hardened to a depth of 0.008 inches with a Rockwell 15-N hardness of 89.2 to 90.2. The feed wheel shall have sharp teeth equally spaced around the wheel circumference and shall be permanently attached to the wing type handle by a metal shaft passing through the opener body. Testing shall be as specified in 4.3 and 4.4.
2.2.3 Cutting wheel. The cutting wheel shall be fabricated of free machining steel. The cutting wheel shall be chamfered to a sharp cutting edge and mounted on a plier or cam type pressure device which is engaged when pressure is applied by squeezing the handles. The cutting wheel shall be at an angle of 20 to 30 degrees with the surface of the feed wheel. The edge of the cutting wheel shall not come in contact with the feed wheel edge. The cutting wheel shall be case hardened to a depth of 0.006 inches. Using the Knoop microhardness test at a 400 gram load, the following hardness ranges shall be required: 0.002 inches = 600 - 700; 0.004 inches =
550 - 700; 0.006 inches = 500 - 700. Testing shall be as specified in 4.3 and 4.4.
2.3 Lubrication. All points of the can opener requiring lubrication shall be lubricated with the manufacturer's recommended food service equipment grade lubricant.
2.4 Standard compliance. Fabrication of the hand held can opener shall comply with the requirements of NSF International Standard No. 2 as specified in 4.2.
2.5 Metric products. Products manufactured to metric dimensions will be considered on an equal basis with those manufactured using inch-pound units, provided they fall within the tolerances specified using conversion tables contained in the latest revision of IEEE/ASTM SI
10, and all other requirements of this CID are met. If a product is manufactured to metric dimensions and those dimensions exceed the tolerances specified in the inch-pound units, a request should be made to the contracting officer to determine if the product is acceptable. The contracting officer has the option of accepting or rejecting the product.
2.6 Workmanship. The finished hand held can opener shall be clean and free of rust, slivers, burrs, deep scratches, pits, and tool marks. Surfaces shall be free of loose or flaked plating. All sharp edges and corners shall be removed. The can opener shall not be bent, damaged, or distorted. There shall be no defects which impair the durability, appearance, or serviceability of the item.
