This part ofISO3951is primarily designed for use under the following conditions:a)where the inspection procedure is to be applied to a continuing series of lots of discrete products all supplied by one producer using one production process;b)where only a single quality characteristic,x, of these products is taken into consideration, which must be measurable on a continuous scale;c)where production is stable (under statistical control) and the quality characteristic,x, is distributed according to a normal distribution or a close approximation to the normal distribution;d)where a contract or standard defines a lower specification limit,L, an upper specification limit,U, or both; an item is qualified as conforming if and only if its measured quality characteristic,x,satisfies the appropriate one of the following inequalities:1)x≥L(i.e. the lower specification limit is not violated);2)x≤U(i.e. the upper specification limit is not violated);3)x≥Landx≤U(i.e. neither the lower nor the upper specification limit is violated).
