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.
