Batch / Batch number

All articles coming out of the whole of one production line (production, assembly, filling, packaging, etc.) belong to one so-called batch. They are provided with a number code, the so-called batch number, for identification. Due to manifold causes, (the slightest) differences may occur in every new production line. Example - the purchase and/or later purchase of paints: The batch number guarantees that each single container originates from the same batch to avoid e.g. different colour shades. In case of defects (e.g. impurities in food, vehicle quality defects, etc.), all articles of the respective batch can be recalled.
