1. In accordance with the following table, samples of approximately equal size shall be extracted evenly from the whole of the rendered material. These samples shall then be divided into groups of approximately equal numbers, the number of groups being the number of aggregate samples specified in the table. The samples in each group shall then be mixed together to form aggregate samples.
| Total quantity of rendered material consigned from the premises | Number of samples extracted | Number of aggregate samples obtained by mixing the relevant number of samples |
|---|---|---|
| Loose animal protein | ||
| up to 1 tonne | 7 | 1 |
| 1–2.5 tonnes | 7 | 2 |
| 2.5–10 tonnes | √20 × weight of sampled portion in tonnes | 2 |
| 10–40 tonnes | √20 × weight of sampled portion in tonnes | 3 |
| over 40 tonnes | √20 × weight of sampled portion in tonnes | 4 |
| (maximum – 40 incremental samples) | ||
| Bagged animal protein | ||
| 1–16 bags | 4 | 1 |
| 17–200 bags | √No. of bags of sampled portion | 2 |
| 201–800 bags | √No. of bags of sampled portion | 3 |
| over 800 bags | √No. of bags of sampled portion | 4 |
| (maximum – 40 incremental samples) | ||
2. Each aggregate sample shall be placed into a separate sterile receptacle and each shall be thoroughly mixed by stirring or shaking.
3. Approximately equal amounts shall be taken from each aggregate sample and mixed so as to provide a single final sample of approximately 500 grammes. This final sample shall be transferred into a suitable sterile screw top container which shall then be sealed and marked to indicate its identity.

| 1–5 consignments | 1 per consignment | 1 |

For the purpose of this method “consignment” means the total quantity of rendered material loaded onto a single vehicle or trailer.
