Use information: This paragraph is informational only and is not 
    exclusively definitive of the end use.
  For high quality offset printing of announcements, certificates, 
citations, enrolled bills, etc., requiring processing through high speed 
copier or laser printer (90 g/m\2\ stock only); execution with pen and 
ink; erasing quality; and highest degree of permanence (archival 
quality) when specified. Printed matter may include text and line 
illustrations; suitable for embossing.

Unless the option below is specified, the following `basic' 
    specification applies.
Stock: 100 pct bleached chemical woodpulp.

    Note: \1\ Postconsumer fiber, in any percentage, is encouraged, 
  provided that the requirements of this Standard are met.

Grammage (g/m2).......................................       90      177
  Basis weight: 17 by 22 inches, 500 sheets (pounds)..       24       47
  A tolerance of 5 pct shall be allowed.

Folding endurance: Average, each direction, not less than--
  M.I.T. (double folds)...............................       30       30
Ruling and writing qualities: Lines ruled or characters written with pen 
  and ink shall be clear 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.

Watermark: Paper shall not be watermarked.
Curl: Paper shall lie flat before and after processing through a copier 
  or laser printer with either no tendency to curl or with a curl which 
  can be overcome under reasonable working conditions.

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 the white paper not less than 79 pct. The color 
  variation shall not exceed DE(CIELAB)=1.0.

    For colored stock, paper shall match one of the established 
  standards or as specified. 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 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.

    Option A: Alkaline paper. This option is for products requiring 
                      permanence (archival quality).
  The following requirements replace the same in the `basic' 
specification and are added to the specification.

Acidity: pH value by cold extraction shall be not less than 7.5. The 
  paper shall contain not less than 2 pct calcium carbonate.

    Any deviation in this requirement shall be sufficient cause for 
  rejection of the paper.
Tearing strength: Average, each direction not
  less than (mN)........................................     500     990

  Equivalent (grams)....................................      51     101

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, and folding 
  endurance. 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.)


 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 sheet 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 1.0 DE unit between 
  felt and wire sides is permitted.

Surface: Shall be free from lint, fuzz, or any particles which will 
  pick, lift, fluff, or pile on the blanket under normal press 
  conditions. Paper shall lie flat with either no tendency to curl or 
  with a curl which can be overcome under reasonable working conditions.
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 x 356 mm (8\1/2\ x 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.
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.


    \1\ This grade is typically a low Government usage paper and 
currently not readily and/or economically available with postconsumer 
fiber content. If a postconsumer fiber content is desired in the paper, 
that number will be stated in the procurement document.
