Ribbon flagging TY i CL 3 GR m white & yellow stripe awarded IAW p/n 5001-y/wand GSA advantage price following the IPD, incorporated and made part of this order L7 ribbon, flagging, surveyor s: shall be in accordance with the following characteristics: color white and yellow stripe. Length per roll 100 yards. Maximum age on delivery two (2) months from date of manufacture. Unit of issue BX (twelve (12) rolls per box). Scope this description covers striped, plain colored, plastic ribbon designed for use as a flagging marker in field survey work and for otherwise designating or identifying specific outdoor objects and locations. Description - the plastic flagging ribbon shall be fabricated from flexible vinyl plastic film. Plasticizers used shall be appropriate for the ribbons to remain supple at minus 20 degrees f, when tested in as specified below. Dimensions the plastic film shall have a measured thickness of 0.0018 inch minimum and a width of 1-3/16 inches + 1/32 inch. Each roll shall contain a minimum of 100 yards of plastic ribbon. Weight the 100 yard roll, less core, shall weigh a minimum of 5.85 ounces. Weight per roll shall be determined by using specific gravity as determined in accordance with astm d 792 and the following formula: yards/LB. = .77 (SG x width x thickness). Colorfastness the color of the flagging ribbon shall show no change in basic color, when examined visually, after 276 hours in a xenon ARC fade-o-meter/weather-o-meter, when tested as specified below (the basic color may be faded or a lighter shade, but the original color is still identifiable and recognizable). Tensile strength 5.0 LB, minimum. Elongation 150 percent minimum. Specific gravity 1.34 to 1.44 GR/CC. 100% modulus 1,600 PSI minimum. Workmanship the ribbon shall be free of holes, dirt, ragged edges, discoloration, and be suitable for the purpose intended. No defects that affect appearance or serviceability shall be permitted. Testing. Weight the weight per roll without core shall be determined by using a balance readable to 0.1 gram or less. Thickness the gage used for the measurement of thickness shall be a dead weight type equipped with a dial graduated to read directly to 0.0001 inch. The presser foot shall be circular with a diameter of 0.25 inch + 0.01 inch. The presser foot and moving parts connected therewith shall be weighted so as to apply a total load of 3 ounces + 0.1 ounce to the specimen. The presser foot and anvil surface shall be plane to within 0.0001 inch and parallel to each other within 0.0001 inch. Low temperature resistance three eight-inch lengths of the finished ribbon from each sample unit shall be exposed in cold chamber to a temperature of minus 20 degrees f + 4 degrees f for a period of 1 one hour. Without being removed from the cold chamber, the specimen shall be creased 180 degrees in the center by folding slightly while lying on a flat smooth surface running the center of a steel roller over the fold a single time. The steel roller shall be approximately 5.5 inches in diameter, approximately 2 inches wide, with a suitable handle guide and shall weigh 10 pounds + 0.5 pounds. The temperature of the roller shall be the same as that of the specimen. The specimen shall be handled with gloves and care taken that IT s temperature remains uniform trough the test. After folding, the specimen shall be visually examined. Any indication of cracking or flaking of any specimen shall be cause for rejection. Colorfastness the finished ribbon shall be exposed for the specified number of hours in accordance with astm g 155-00AE1 (use corresponding cycles equivalent to astm g 26, methods a or c) and examine for compliance with colorfastness requirements above. Tensile strength and elongation shall be determined in accordance with astm D638. 100% modulus shall be determined in accordance with astm D882. Specific gravity shall be determined in accordance with astm D792. Product conformance: the pro
