3.5.2 inspection level

In the ISO 29/1 procedures, increased sample siz, cotre onds to a greater protection for the consumer. In this oart of ISO 28O,

consumer protection is held approximately constant and the effect of increasing sample oz is to permit the

supplier greater latitude in me perimtted process averages. I? the consumer Is satisfied by the protection provided dcjdlrlst an

occasional poor lot by the nominal limiting quality, then the in spection level is pnmary of intei-e,t to the upplir, especially if the costs of the sampling Inspection are borne by him. A process average well below the limiting quality (better quality) would

allow the use of smaller sample sizes, Conversely, if the consumer is concerned with actual rather than limitng quality. Ui if he

pays to. the costs, then yledle. inspection levels are not necessary advantageous. For this reason, inspectmn level has not been incor. porated In this part of ISO 2859 to limiting qualIties greeter than 5 %. When

sample sizes have to be kept small and other considerations ste secondary, specifying level S-2 has the effect of providing a fixed sample size for all lot sizes, the sample size depending only on the limiting quality.
