  for determination of compliance during a single work shift and are of the same item description,
  weight range, date of acceptance, etc. For the purpose of these provisions the size of a lot shall be

  A process of selecting a sample from a lot whereby each unit in the lot has an equal chance of selection.
• Rejection Number (Re)
  The number in a sampling plan that indicates the minimum number of defects in a sample that will
  cause a lot to fail a specific AQL.
• Sample

• Sample unit
  An individual item (roast, chop, steak, etc.) or designated quantity of product to be part of a sample.
• Slight amount of lean removed

  usability of that item.
• Small amount of lean removed
  Amount of lean removed from the major muscles of an item that, regardless of the location, materially
  affects the usability of that item.
• Stationary Lot Sampling plan
  A plan stating the number of sample units to be included in the sample as well as the corresponding
  acceptance and rejection criteria. The decision to accept or reject a lot with respect to a specified AQL
  is made after the inspection of a sample or when the number of defects exceeds the acceptance number.
  100-Percent. A method of examination in which all items within a lot are examined. Items not fully
