18、r 0.6750.67A negative value for CPK indicates that the mean is outside the specification limits. A CPK of zero indicates that the meanis equal to one of the specification limits. A CPK between 0 and 1.0 means that part of the 6 sigma limits falls outside thespecification limits. A CPK of 1.0 means t

19、hat one end of the 6 sigma limits falls on a specification limit. A CPK larger than1.0 means that the 6 sigma limits fall completely within the specification limits. See Explanatory Note 1 for an example inter-pretation of CPK values and actions to follow.Capability indices are useful tools in the a

20、nalysis of capability data. The most useful index is CPK, since it formulates capa-bility in a manner that relates to shifts in the mean of the distribution away from the midpoint.3.1.4 lota group of production units of one type and size of wire, which were produced during the same time period under

21、similar production conditions, and are presented for acceptance at the same time.

Original inspection is the first inspection ofa particular quantity of product as distinguished from the inspection of product that has been resubmitted after prior rejection.When double or multiple sampling is used, only the first sample
