These categorizations don't have any hierarchical importance. Attainment with the chemical indicator’s finish level shouldn't be considered to be a sign of attainment of an appropriate sterility assurance amount, but rather a single of many aspects which must be taken into account when judging the acceptability of a sterilization method.
Acid-foundation indicators should be chemically pure and never react with other substances in get more info the solution at a typical state.
