COMMERCIAL ITEM DESCRIPTION
CORRECTION FLUID, DUPLICATING MACHINE STENCIL
The General Services Administration has authorized the use of this
Commercial Item Description in lieu of Federal Specification TT-C-621.
This commercial item description covers one type of stencil correction fluid for use on dry-process stencil paper.
Salient characteristics:
Correction fluid shall be a low viscosity fluid consisting of resins dissolved in a volatile solvent.
Fluid shall be furnished packaged in 1-oz glass or plastic bullets with an integral application brush.
Correction fluid shall have a flash point under 100oF which shall be determined according to ASTM D 1310.
Bottle and individual packages shall be clearly labeled “Flammable”.
Viscosity shall be not more than A at 25oC (77oF) and shall be not less than tube A-3 at 25oC (77oF) when tests are performed with procedures specified in ASTM D 1545. Standard viscosity reference tubes marked A to A-3 should be used.
Fluid shall be capable of drying without tackiness or chalking and have good flexing properties. The fluid shall dry within 45 seconds under conditions of 20o to 25o C and relative humidity of 50 to 65 percent.
Fluid shall be capable of being thinned. The fluid shall be capable of being spread easily by brush in one application over a typewritten letter on dry process stencil paper so as to permit easy correction.
Labeling. Each glass or plastic bottle container shall be labeled in accordance with the appropriate Federal states and regulations. In addition, the following information shall appear on the label in clearly discernible an legible letters:
“Correction Fluid for Dry Duplicating Stencils”
Danger-Extremely flammable
Keep away from heat, sparks or flame
Keep out of reach of children
The name of the manufacturer and the quality of fluid contained in the bottles shall also appear on the label. The date of manufacture shall appear on the label or be prominently marked elsewhere on the cap or paperboard box.
Spreading qualities. Over a single letter of a typewritten work in stencil paper, spread the correction fluid with the brush that is provided. The fluid shall spread easily and sufficiently in one application. Allow to dry for 30 seconds. Type onto the treated space the desired letter. Examine: The typed letter shall appear satisfactory, with the letters adjacent to the corrected spaces unaffected.
Working qualities. Use dry stencil paper and prepare as follows: Type two lines of capital “B” using single spacing between lines, and type three lines of the word “stencil” using a single space between words and single spacing between lines. Draw 10 parallel horizontal lines 4 inches long spaced 1/4 inch apart. Draw over the horizontal lines at an angle of 60o with the horizontal lines spaced 1/8 inch apart (lines shall be drawn with a medium loop stylus). Treat one-fourth of the typewritten and drawn lines with the correction fluid portioning out the test area over the entire stencil. Retype, substituting “J” for “B” and “uniform” for “stencil”., Remove the cushion sheet (the cushion sheet shall be capable of being suitably separated from the stencil). Place the stencil in a duplicating machine and prepare 5,000 copies. Examine several of the final copies. The corrected areas shall be equal in clarity and legibility to the remainder of the typewritten and drawn matter. Remove stencil from the duplicating machine and replace the stencil on the machine after 10 minutes. Prepare 25 copies. Examine the last copy. The corrected areas shall be equal in clarity and legibility to the typewritten and drawn matter.
The issue of ASRM test method in effect on the date of the solicitation shall be used to determine with stated requirements.
