How to Prepare a Flash Memory Product Acceptance Agreement
An acceptance agreement converts informal expectations into test criteria that both buyer and supplier agree to before production. It fixes the sampling plan, the test method, the pass/fail thresholds and what happens to a non-conforming unit — and it should be reached up front, not argued over after the goods land. Agree it alongside the sample approval so the batch you receive is judged by the same rules the sample passed.
What an acceptance agreement should contain
| Element | What it fixes |
|---|---|
| Sampling plan | Method and size, agreed — not assumed |
| Test method | Capacity write-and-read-back, sustained write, compatibility |
| Pass / fail thresholds | Numbers with limits, not vibes |
| Non-conforming handling | Rework, replace or reject — decided upfront |
| Retained sample | A tested unit kept for dispute comparison |
Sampling is a choice, not a fixed law
There is no single sampling percentage or AQL that every flash product must obey. The proportion and level are agreed between the parties based on product risk, order value and what is practical to test. The discipline is that it is written and repeated, not that it matches a number found online.
Tests to specify
- Full capacity write-and-read-back (proves capacity, not speed)
- Sustained write on the actual target device where the workload is continuous
- Host compatibility on your own hardware
- Appearance, logo and packaging against the approved sample

When should the agreement be signed?
Before production begins, ideally together with sample approval. Reaching it after delivery turns every finding into a negotiation.
Does a capacity test cover everything?
No. It proves the card holds its claimed capacity. Speed, endurance and real-device behaviour need their own specified tests.
What if a batch fails the agreed criteria?
That is why the handling is agreed in advance — rework, replacement or rejection should be written, not improvised. See what happens if a batch fails inspection.
