Division 2 Number of incremental samples
United Kingdom
The aggregate sample uniting all incremental samples shall be at least 1 kg (see point II.5).
The minimum number of incremental samples to be taken from the lot or sublot shall be as given in Tables 3 and 4.
In the case of bulk liquid products, the lot or sublot shall be thoroughly mixed insofar as possible and insofar as it does not affect the quality of the product by either manual or mechanical means immediately prior to sampling. In that case, a homogeneous distribution of contaminants is assumed within a given lot or sublot. It is therefore sufficient to take three incremental samples from a lot or sublot to form the aggregate sample.
The incremental samples shall be of similar weight. The weight of an incremental sample shall be at least 100 grams.
Departure from this procedure must be recorded in the record provided for under point II.8 of this Annex. In accordance with the provisions of Commission Decision 97/747/ECf1, the aggregate sample size for hens' eggs is at least 12 eggs (for bulk lots as well as for lots consisting of individual packages, Tables 3 and 4 shall apply).
Table 3
Minimum number of incremental samples to be taken from the lot or sublot
| Weight or volume of lot/sublot (in kg or litre) | Minimum number of incremental samples to be taken |
|---|---|
| < 50 | 3 |
| 50 to 500 | 5 |
| > 500 | 10 |
If the lot or sublot consists of individual packages or units, then the number of packages or units which shall be taken to form the aggregate sample is given in Table 4.
Table 4
Number of packages or units (incremental samples) which shall be taken to form the aggregate sample if the lot or sublot consists of individual packages or units
| Number of packages or units in the lot/sublot | Number of packages or units to be taken |
|---|---|
| 1 to 25 | at least 1 package or unit |
| 26 to 100 | about 5 %, at least 2 packages or units |
| > 100 | about 5 %, at maximum 10 packages or units |
