Ee122 first verify your email before subscribing to alerts. The level of a characteristic may often be taken as an indication of the quality of a material.

This standard is not included in any packages. 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. Dimensional quantities in the standard are presented only as illustrations of calculation methods.

We have no amendments or corrections for this standard. Proceed to Checkout Continue Shopping. The examples are not binding on products or test methods treated.

If the process is not in a state of statistical control, the result will not have predictive value for immediate future production. Dimensional quantities in the standard are presented only as illustrations of calculation methods.

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.

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 e1222 as an average value or as a fraction not conforming to a specified value. If the process is not in a state of statistical control, the result will not have predictive value for immediate future production.

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 asttm 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 standard is also s122 to be included in Standards Subscriptions. Already Subscribed to this document.

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. Dimensional quantities in the standard are presented only as illustrations of calculation methods.
