We have no amendments or corrections for this standard. ISOPart 1: Historical Version s – view previous versions of standard. The practice applies when 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 standard also provides guidance on the selection of the appropriate inspection system for use in a particular situation.
Applied statistics ISOPart 3: Already Subscribed e12-09 this document. 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. During the last few years, the ISO standards on this topic have seen greater usage as well. 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.
The level of a characteristic may often be taken as an indication of the quality of a material. Subscription pricing is determined by: General statistical terms and terms used in probability.

It can also be used to establish practical estimations of the various measures by experiment.
General principles and definitions, is an introduction to the ISO series. 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.
