What the certificate looks like
Four documents off one set of results. A variant chooses what to print, never what was measured.
| Document | Accounts | Also prints | Because |
|---|---|---|---|
| General certificate COA-GENERAL | 26 | The release tests only | What most accounts receive. Release tests, result against specification, and the batch it came from. |
| Pipe extrusion variant COA-PIPE | 5 | Black specks, Pour density | Pipe extruders read speck count off the plaque because it shows on the finished pipe. Reported, not released on. |
| Food contact variant COA-FOOD | 5 | Loss on drying, Vegetable origin | Food and personal care accounts. Adds the origin declaration and loss on drying. |
| Export and intercompany variant COA-EXPORT | 12 | Loss on drying | Adds country of origin, which customs at the far end asks for. |
