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.

number.
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
