tolerable levels of potential decision errors that will be used as the
basis for establishing the quality and quantity of data needed to support
decisions. |

details the method for an operation, analysis, or action with thoroughly
prescribed techniques and steps, and that is officially approved as the
method for performing certain routine or repetitive tasks. |
|

|
Surrogates = |
Surrogate compounds are substances normally not found in
nature that are intentionally added at a known concentration to a sample
