e12-09 The practice treats the common situation where the sampling units can be considered to exhibit a single overall source of variability; it does not treat multi-level sources of variability. We have no amendments or corrections for this standard.
The standard also provides guidance on the selection of the appropriate inspection system for use in a particular situation. The practice applies awtm quality is expressed as either the lot average for a given property, or as the lot fraction not conforming to prescribed standards.

This practice will clearly indicate the sample size required to estimate the average value of some property or the fraction of nonconforming items produced by a production process during the time interval covered by the random sample.
The practice treats the common situation where the sampling units can be considered to exhibit a single overall source of variability; it does not treat multi-level sources of variability.

ISOSampling procedures for inspection by attributes — Part This practice is intended for use in determining the sample size required to estimate, with specified precision, such a measure of the quality of a lot or process either as an average value or as a fraction not conforming to a specified value.
Introduction to the ISO series of standards for sampling for inspection by attributes, is a good starting point for the ISO set. The standard may be applied to a very wide range of materials, including liquids, powders and solid objects, manufactured or naturally occurring.
General statistical terms and terms used in probability. Already Subscribed to this document. As the voice of the U. It provides a general introduction to acceptance sampling by attributes and provides a brief summary of the attribute sampling schemes and plans used in Parts 1 through 5.
