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

§3.3Resulting amendments

1. A determination does not record the version of the standard it was made under — arising from DRAFT-AGGREGATES-S/002. 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.
2. The matrix interferes with the determination and no control is required — arising from DRAFT-AGGREGATES-S/003. An inhibition and enhancement control is now required for every determination under this standard, with stated recovery limits, and a determination reported without it is recorded as not conformant rather than as a low result.
3. The standard assumes a reference standard of known assigned content — arising from DRAFT-AGGREGATES-S/004. The standard now states which determinations remain available without a reference standard of assigned content, requires that such determinations be labelled as relative rather than absolute, and requires the assumption used in place of an assigned content to…
4. Point estimates are given without an interval — arising from DRAFT-AGGREGATES-S/005. Every estimate now carries its interval where the source reported one, and where it did not, the estimate is annotated as reported without an interval rather than left to appear as a precise figure.
5. The additional determinations required would materially increase release testing cost — arising from DRAFT-AGGREGATES-S/006. One of the two determinations is now required only where the stated risk factor is present, with the factor defined in the scope, and the other is retained as a universal requirement with the reasoning stated. The submission is identified as an industry…
6. The standard does not state that a determination on one unit says nothing about the batch — arising from DRAFT-AGGREGATES-S/007. Every determination made under this standard now carries a sampling statement recording how many units were sampled, from what population and by what plan, and the standard states that a determination on a single unit supports no inference about any other…
7. Nothing in the standard addresses transfer of the method between laboratories — arising from DRAFT-AGGREGATES-S/008. The standard now states the maximum difference between laboratories analysing the same sample at which results are treated as agreeing, and requires that a comparison across laboratories state whether that criterion was met.
8. Rounding conventions are not stated and change the reported result — arising from DRAFT-AGGREGATES-S/009. The standard now requires that no rounding be applied before the reporting step, states the reporting precision for each quantity, and states the rounding convention used at that step.
9. Nothing requires a laboratory to demonstrate ongoing performance — arising from DRAFT-AGGREGATES-S/010. 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.
10. Absence of evidence is presented in a form a reader will take as negative evidence — arising from DRAFT-AGGREGATES-S/011. A standing formulation has been adopted and is applied wherever an evidence gap is recorded, distinguishing an outcome assessed and not demonstrated from an outcome not assessed. The formulation is identical at every occurrence so that it can be recognised at…
11. Nothing addresses the container the material was held in — arising from DRAFT-AGGREGATES-S/012. Container type and headspace atmosphere are now reported where known, and recorded as not held where they are not, rather than omitted.
