Scope

What is BS ISO 3951-1:2022 Sampling procedures for inspection by variables about? This document is the first in a multi-part series that applies statistical methods to sampling in order to control the acceptance of quality products.   ISO 3951-1:2022 details sampling plans indexed by acceptance quality limit with inspection for a single quality characteristic. Who is ISO 3951-1:2022 Sampling procedures for inspection by variables for? Any organization purchasing or selling items where there is a need to stay within specification limits What does ISO 3951-1:2022 Sampling procedures for inspection by variables cover? ISO 3951-1 specifies single sampling plans for lot-by-lot inspection under the following conditions: Where the inspection procedure is applied to a continuing series of lots of discrete products all supplied by one producer using one production process Where only a single quality characteristic, x, of these products is taken into consideration, which must be measurable on a continuous scale 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 Where a contract or standard defines an upper specification limit U, a lower specification limit L, 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: x ≥ L (i.e., the lower specification limit is not violated) x ≤ U (i.e., the upper specification limit is not violated) x ≥ L and x ≤ U (i.e. neither the lower nor the up...
