Metric Conversion Act: The P.L. 100-418 (The Omnibus Trade and 
  Competitive Act of 1988) section 5164 designates the Metric system of 
  measurement as the preferred system of weights and measures for the 
  United States trade and commerce.

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.
