–ConformityNot assessable
every reported unit passed on all 6 test rows · QA approval corroborates: Vanguard Laboratory, Tori Johnson, Operations Manager, 2025-12-30 · QA approval corroborates: Eagle Analytical Services Inc., Alison Eng, Quality Control Manager, 2025-12-23 · house check · agreement across all tests, unit to unit; QA approval corroborates
A chapter number names the method or limit a result follows; it does not describe the product. Chapters below 1000 are procedures or limits; 1000-series chapters are informational. USP <905> is the compendial test for between-unit uniformity: it assays 10 units, so a 3-unit certificate cannot yield its acceptance value — the content row is a house check with <905> named as the reference only.
