    A tolerance of 0.008 mm (0.0003 inch) shall be allowed 
  on the 45 g/m\2\ and 0.013 mm (0.0005 inch) on the 60, 75, 
  90, and 
  105 g/m\2\ paper. Paper shall be uniform and shall not vary more than 
  0.011 mm (0.0004 inch) from one edge to the other.
General appearance: Paper shall conform to the standard sample(s) 
  adopted by the Government.
  Color: The paper in the order (or publication) shall be uniform with a 
  target brightness of 79 pct for the white paper. The color variation 
  shall not exceed DE(CIELAB)=1.0. For cream white, the color 
  coordinates are included in Part 3.
  Finish and formation: Shall be uniform.
  Cleanliness: The dirt count for each side of the paper shall not 
  exceed 250 specks per square meter. No sample sheet (600 to 650 cm\2\ 
  in size) shall contain more than one defect with an equivalent area of 
  0.25 mm\2\ or greater.
Sampling and testing: Shall be conducted in accordance with standards in 
  Part 2, Government Paper Specification Standards. The precision 
  requirements of the acceptance criteria (Part 4) shall apply for all 
  properties except for stock, acidity, filler content, folding 
  endurance, and brightness. Any deviation in the ``excepted'' 
  properties is a critical defect and shall be sufficient cause for 
  rejection of the paper. Prior-to-production testing of paper is 
  required. Conformance to these requirements will permit the printing 
  of the infinity symbol () in the document or publication. 
  (Reference: ANSI/NISO standard Z39.48-1992.)

  printing or duplicating is to be accomplished on commercial contract
Sizing: Paper shall be surface- and internal-sized suitable for 
  satisfactory printing on both sides of the paper on high-speed offset 
  presses equipped with continuous flow or brush dampening systems.
Pick resistance: Average, each side, not less than 13-A Dennison wax 
    No individual specimen shall average less than 11-A Dennison wax 
Color: Shall match the Government's standard sample for color. A 
  deviation of DE(CIELAB)=3.0 from the color standard is allowed.
Curl: Paper shall lie flat with either no tendency to curl or with a 
  curl which can be overcome under reasonable working conditions.
Surface: Shall be free from lint, fuzz, or any particles which will 
  pick, lift, fluff, or pile on the blanket under normal press 
Size and trim: Sheets: Paper shall be furnished in the size(s) ordered 
  and shall be flat, trimmed square on four sides with clean smooth 
  edges, and evenly jogged. A tolerance of 2 mm (\1/16\ 
  inch) shall be allowed except for sheets 216 by 356 mm (8\1/2\ by 14 
  inches) or less; then a tolerance of 1 mm (\1/32\ inch) 
  shall be allowed. Successive sheets within any package shall not 
  differ from each other by more than 0.5 mm (\1/64\ inch). Paper with 
  the long dimension 813 mm (32 inches) or less shall be considered 
  square if the variation does not exceed 1 mm (\1/32\ inch); over 
  813 mm (32 inches), 2 mm (\1/16\ inch).

fiber content. If a postconsumer fiber content is desired in the paper, 
that number will be stated in the procurement document.
