The accuracy of such mechanical volumetric dispensing devices already must be checked on a quarterly use basis as required by section 5.
PT sample stability assessments shall be based on analytical data comparing the mean of a series of random samples analytically tested before the start of a study to the mean of a series of random samples analytically tested after the study close date. Specification concerning assigned values, data evaluation and acceptance limit calculations have been added for the inclusion of Protozoan PT programs. standare
