ISOSampling procedures for inspection by attributes — Part Introduction to the ISO series of standards for sampling for inspection by attributes, is a good starting point for the ISO set. It provides a general introduction to acceptance sampling by ast, and provides a brief summary of the attribute sampling schemes and plans used in Parts 1 through 5. The standard also provides guidance e122–09 the selection of the appropriate inspection system for use in a particular situation.
Catalog of Tools and Techniques, are two additional useful standards. They provide concepts, tools and techniques to help an organization in planning, implementation and evaluation of an effective statistical process control SPC system.

It can also be used to establish practical estimations of the various measures by experiment. The standard may be applied to e122-90 very wide range of materials, including liquids, powders and solid objects, manufactured or naturally occurring.
ISOPart 1: General statistical terms and terms used in probability. ISOPart 2: ISOPart 3: We often sell the following:.
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 the lot average for a given property, or as the lot fraction not conforming to prescribed standards.
