Mimeograph quality: See No. 9 Government Paper Specification Standards
for details of this test.
Minimum content standards: The minimum percentage of recovered fiber
recommended by the Environmental Protection Agency (EPA) for Federal
procurement of paper and paper products and stated in the paper
specification standard. This percentage is based on fiber weight.

Oil holdout (of coating): Use method T-462, except the end point shall
be evaluated at 200 seconds. When viewing from the underside of the
paper in the mirror, record the time it takes the oil to penetrate the
coating or at 200 seconds: ``did the oil penetrate the coating of the
paper?'' The report shall be the number of seconds it took the oil to
penetrate the coating or ``>200 s'' if the oil does not penetrate the
coating at 200 seconds. (Note: The endpoint for this test is not the
same as the endpoint for oil penetration T-462.)
Oil penetration: Use method T-462.
Opacity: Use method T-425.
Optical brightener: Use method T-452, appendix C.
