§3.2Summary by disposition

Table 2. Counts by disposition, with the meaning of each.

DispositionCountMeaning
Accepted2The submission is accepted and the draft is amended as proposed. The amendment is recorded in the amendment log of the document it changed and is traceable to the numbered submission.
Accepted in part1Part of the submission is accepted and part is not. The secretariat response states which part is which and on what ground the remainder was declined.
Noted, no amendment0The submission raises a point the Institute accepts but that does not require a change to the draft, most often because the draft already states it elsewhere. The location is given in the response.
Not accepted1The submission is not accepted. The secretariat response gives the reason. A submission that is not accepted remains published in full; the Institute does not remove a submission because it disagrees with it.

§3.3Resulting amendments

  1. Nothing requires a laboratory to demonstrate ongoing performance — arising from DRAFT-PHOTOSTABILI/001. The standard now requires that system suitability results be trended across runs and that a determination report whether the trend was within the laboratory's stated limits, which places the demonstration inside the document the Institute can read.
  2. A determination does not record the version of the standard it was made under — arising from DRAFT-PHOTOSTABILI/004. Every determination reported under this standard now carries the standard identifier and version on its face, and a claim of conformance that does not identify the version is recorded by the Institute as not conformant.
  3. The scope does not say which materials the standard excludes — arising from DRAFT-PHOTOSTABILI/003. The scope now states both what the standard applies to and what it does not, with the excluded classes named and, where another standard covers them, cross-referenced.
