Requirements for submission
General instructions when submitting samples:
- Pack the material in plastic.
- Dispatch the sample in a sturdy box. Attach the submission form to the outside of the box.
- Seed samples submitted for moisture content determination should be submitted in moisture-tight packaging.
- If your test sample is labelled URGENT, it will be treated as such and tested as quickly as possible. A special rate for urgent testing will be charged (see list of fees).
As well as the general instructions, other instructions may apply depending on the nature of the material submitted.
- For Naktuinbouw attests always send in at least twice the required amount of seed. This will avoid delays if a repeat rest has to be carried out.
