    Note: Not less than 20 pct postconsumer fiber. Any percent over 20 
  percentage points, is encouraged, provided that the requirements of 
  this Standard are met.

Acidity: pH value shall average not less than 6.5 for white paper and 
  5.0 for colored paper.

  A tolerance of 10 pct shall be allowed.

Bursting strength: Average,
  not less than (kPa)...............      270      340      410      520
  Equivalent (lb/in \2\)............       40       50       60       76

  Equivalent (inch).................   0.0075   0.0091   0.0114   0.0138

    A tolerance of 0.013 mm (0.0005 inch) shall be allowed 
  on the 165, 200, and 255 g/m\2\ paper and 0.020 mm (0.0008 
  inch) on the 305 g/m\2\. Paper shall be uniform and shall not vary 
  more than 0.011 mm (0.0004 inch) from one edge to the other.

Ruling and writing qualities: Lines ruled and characters written with 
  pen and ink 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. Samples from the delivery shall show no greater 
  resistance than the standard sample to removal by abrasion of 
  typewritten characters.

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 
  the brightness of the white paper not less than 81 pct. The color 
  variation shall not exceed DE(CIELAB)=1.0.
    For colored stock, paper shall match one of the established 
  standards. Standards are blue, buff, pink, salmon, or yellow. Colors 
  shall not fade and shall appear even and uniform on the surface of the 
  sheet. Stock shall not be 2-sided. Color coordinates for selected 
  standards are included in Part 3.
  Finish and formation: Shall be uniform.
  Cleanliness: The dirt count for each side of the paper shall not 
  exceed 650 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.

 Option A: Alkaline paper. This option is for products requiring above 
                            average permanence.
  The following requirements replace the same in the `basic' 
specification or added to the specification.
Stock: 100 pct bleached chemical woodpulp.

    Note: Postconsumer fiber, in any percentage, is encouraged, provided 
  that the requirements of this Standard are met.
Acidity: pH value, by cold extraction of the white stock shall be not 
  less than 7.0. The paper shall contain not less than 2 pct calcium 
    Any deviation in this requirement shall be sufficient cause for 
  rejection of the paper.


 Unless otherwise specified, the following is automatically waived when 
  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.
Color: Shall match the Government's standard sample for color. A 
  deviation of DE(CIELAB)=3.0 from the color standard for white and 2.0 
  for colored stocks is allowed. A color difference between felt and 
  wire sides is permitted.
    For information only, the CIELAB values (Ill D65, 10 deg. observer) 
  of the white 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 dimensions 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).

    Rolls: Roll width and diameter shall be as ordered. A tolerance of 
  2 mm (\1/16\ inch) shall be allowed for width and 
  26 mm (1 inch) for diameter.

Roll winding: Roll paper shall be tightly wound at even tension and 
  shall not contain more than the specified maximum number of splices 
  per roll. The number of splices permitted per roll is determined by 
  the roll diameter as ordered. On rolls 1,016 mm (40 inches) or less, a 
  maximum of three splices per roll shall be allowed. On rolls over 
  1,016 mm (40 inches), a maximum of four splices per roll shall be 
  allowed. Splices shall be neatly and securely overlap-pasted and made 
  with repulpable adhesive which will not permit the splice to separate. 
  The adhesive may be applied from a tape form backing, provided the 
  backing is removed, leaving only the adhesive component on the splice. 
  The adhesive shall not cause the splice to adheare to adjacent laps. 
  The tails of the splices shall be neatly and evenly removed without 
  damage to adjacent laps. Splices shall be flagged at both ends with 
  projecting colored markers, not pasted to the splice, or otherwise 
  clearly marked.

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

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.
