It provides a general introduction to acceptance sampling by attributes and provides ast, brief summary of the attribute sampling schemes and plans used in Parts 1 through 5. 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.

The standard may be applied to a very wide range of materials, including liquids, powders ast solid objects, manufactured or naturally occurring. It can also be used to establish practical estimations of the various measures by experiment. Please first log in with a verified email before subscribing to alerts. General principles and definitions, is an introduction to the ISO series. If the process is not in a state of statistical control, the result will not have predictive value for immediate future production.
If so, an estimate of the average value of that characteristic or of the fraction of the observed values that do not conform to a specification for that characteristic becomes a measure of quality with respect to that characteristic.
