ASTM E122-09 PDF

Nijar It outlines the general principles to be understood when assessing accuracy of measurement methods and results. This standard is intended for use in determining the sample size required to estimate, with specified precision, a measure of quality of a lot or process. The practice applies when quality is expressed as either s lot average for a given property, 1e as the lot fraction not conforming to prescribed standards. The examples are not binding on products or test methods treated.

Nijar It outlines the general principles to be understood when assessing accuracy of measurement methods and results. This standard is intended for use in determining the sample size required to estimate, with specified precision, a measure of quality of a lot or process. The practice applies when quality is expressed as either s lot average for a given property, 1e as the lot fraction not conforming to prescribed standards.

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 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.

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.

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. If the process is not in a state of statistical control, e result will not have predictive value for immediate future production.

We have no amendments or corrections for this standard. This standard is also available to be included in Standards Subscriptions. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for s standards.

They provide concepts, tools and techniques to help an organization in planning, implementation and evaluation of an e statistical process control SPC system. 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 aastm that characteristic.
