A tolerance expressed as a Delta E value defines

  • A.the instrument precision that is required for the measurement
  • B.the lighting in which the finished batch will be seen
  • C.a region around the standard within which a batch is accepted
  • D.the exact colour that every batch must reproduce

Answer: C

The shape of that region depends on the formula chosen. Delta E ab gives a sphere while the weighted formulae give an ellipsoid oriented to the space. Shape follows directly from the weighting used. Equal weights give a sphere in the space.
