Determining the Physical-Sample Sizes
This example shows how the system calculates the number of physical samples and the quantity of each sample based on the information in the inspection plan and the sample-drawing procedure.
How does the system calculate this information based on the above data?

One pooled sample equals the sum of the partial samples defined in the inspection plan |
= |
450 ml |
||
2 |
The size of one pooled sample for one inspection |
= |
450 ml x 1 |
= |
450 ml |
3 |
The size of one primary sample for one inspection |
= |
450 ml / 5 x 1 |
= |
90 ml |
4 |
The size of all primary samples for one inspection |
= |
90 ml x 5 |
= |
450 ml |
In the above example, the quantities of physical samples are only enough for a single inspection. If you want the system to calculate additional quantities of physical samples that will be sufficient for more than one inspection, increase the size factors in the sample-drawing procedure accordingly.
How are the contents of a pooled sample distributed among the laboratories?
