A quantity of material which is known or assumed to be produced under uniform conditions. Some vocabularies assume '
lot' and '
batch' to be synonymous. The distinction made here with respect to knowledge of production history permits a lot to consist of one or more batches and is useful in interpreting the results of analysis.
