3 Terms and definitions

The following terms and definitions apply to this document.

3.1

Batch batch

The number of products from which the test sample is taken to determine its quality.

Note. The same batch of product characteristics should include the same grade, composition, grade, and the same production conditions.

3.2

Delivery batch consignment

The quantity of material delivered once.

Note. A delivery lot can consist of one or more lots, or part of multiple lots.

3.3

Packaging unit unitpackage

A certain amount of material formed by packaging the smallest package. Can be a container bag, it can also be woven bags, paper bags, cans or cans.

Note. Simple temporary packaging is not a packaging unit.

3.4

Sample increment

The amount of material removed from a large batch of material at a time.

3.4.1

Elementary composition

The amount of material extracted once from the packaging unit.
