Writing quality: Characters written with ball point and felt tip pens 
  shall be clear cut and free from excessive feathering.
Erasing quality: Paper shall retain good ruling, writing, and typing 
  quality, texture, and surface appearance, without ink spreading after 
  repeated erasures. After erasures and burnishing, texture shall permit 
  redrawing of sharp lines in ink.
Blocking: Sheets shall not stick together after being wet with water and 
  then allowed to dry in contact with other sheets of the same paper.
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 
  brightness not less than 81 pct. The color variation shall not exceed 
  Formation: Shall be uniform.
  Cleanliness: The dirt count for each side of the paper shall not 
  exceed 100 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.


 Unless otherwise specified, the following is automatically waived when 
  printing or duplicating is to be accomplished on commercial contract
Equilibrium relative humidity: Shall be 45 pct 5 pct at 23  
  deg.C 2  deg.C. Paper shall be uniform and shall not vary 
  more than 5 percentage points in relative humidity from one edge to 
  the other.\2\

    Variations in excess of 5 percentage points shall be sufficient 
  cause for rejection of the paper.

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.

Color: Shall match the Government's standard sample for color. A 
  deviation of DE(CIELAB)=3.0 from the color standard is allowed.

    For information only, the CIELAB values (Ill D65, 10 deg. observer) 
  of the color standard are


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).
Grain: Direction of the grain on flat paper shall be as ordered.

Mill inspection: Uniformity of color, thickness, and equilibrium 
  relative humidity; freedom from foreign matter, either loose or 
  attached to the paper; and absence of mechanical defects such as 
  wrinkles, cuts, slime holes, partial sheets, and dogears; are all very 
  important. Manufacturers are required to make such inspections and 
  tests as will assure freedom from defects in these characteristics.


    \1\ This requirement may be waived by the ordering agency when 
purchasing less than a mill run quantity and so stated in the 
procurement document.
    \2\ This requirement may be waived in whole or part when so stated 
in the procurement document. If waived, the following is applicable:
    Pressroom conditions: The bulk of this paper will be used in air-
conditioned pressrooms maintained at 24  deg.C 2  deg.C and 
45 pct 
8 pct relative humidity.
