ASTM International Standard Practice for Sampling a Stream of Product by Attributes Indexed by AQL ASTM E2234-09(2018)

This practice establishes lot or batch sampling plans and procedures for inspection by attributes using MIL-STD-105E as a basis for sampling a steady stream of lots indexed by acceptance quality limit (AQL). It provides the sampling plans of MIL-STD-105E in ASTM format for use by ASTM committees and others and recognizes the continuing usage of MIL-STD-105E in industries supported by ASTM. This practice also establishes lot or batch sampling plans and procedures for inspection by attributes. The sampling plans described in this standard are applicable to AQL's of 0.01% or higher and are therefore not suitable for applications where quality levels in the range of parts per million levels can be realized. Sampling plans designated in this practice are applicable, but not limited, to inspection of the end items, components and raw materials, operations or services, materials in process, supplies in storage, maintenance operations, data or records, and administrative procedures.
