Covers
Every lot tested; release decision
Provisions
Each compound has a written specification, agreed before any batch is analysed against it
Every batch is sampled and analysed on arrival; verification is per batch, never inherited from a previous lot
Release requires every determination inside specification, with no exceptions granted at the bench
Independent third-party confirmation is obtained before release, and published alongside our own result
The release decision and the analyst who made it are recorded against the lot

an external body. A superseded revision is archived rather than destroyed, so what was
in force on any given date can be established.
