Acceptance Test Specifier
An acceptance test with no numbers in it has no pass mark. Enter the output you are buying, how long you want the test to run and the container you sell in, and this returns the three figures to write into the purchase order, plus the named tests to ask for by name rather than by the words factory acceptance.
This converts your own inputs into contract figures. It invents nothing about the equipment. The 24 hour dry cycle is a commonly specified minimum rather than a SINOFUDE commitment, and the three consecutive runs come from the qualification guidance the page cites, which treats reproducibility as demonstrated over a justified number of consecutive routine runs, generally at least three. What you settle on belongs in the contract before the order is placed, because after commissioning the only leverage left is goodwill.
Turn an output target into contract figures
Why each figure belongs in writing
| Figure | What it fixes |
|---|---|
| Dry cycle hours | How long the machine runs with no product before product is introduced |
| Units the test must produce | Turns a rate into a countable quantity nobody can argue about afterwards |
| Rate the test must hold | Separates an accepted output from a nameplate rating |
| Consecutive runs | One good batch is not acceptance; reproducibility is shown across runs |
| Named tests | IEC 62381:2024 defines four; asking for one of them specifies a quarter of the job |
