MODUK - DEF STAN 05-71: PART 1
Acceptance Sampling Procedures for Proof with respect to Rectangular Reference Targets Part 1 Consistency Proof – Single Sampling Plans for Independent Disturbances in Azimuth and Elevation
|Publication Date:||31 May 2006|
This Part of Def Stan 05-71 establishes single sampling plans and procedures for inspection by variables of the inherent ballistic dispersion of projectiles, when disturbances in azimuth and elevation are independent, or approximately so. The plans in this part of Defence Standard 05-71 are not suitable for acceptance inspection for accuracy, for they take no account of the deviation of the sample mean point of impact from the point of aim. (Sampling procedures for accuracy proof are given in Def Stan 05-71 Part 2).
The objective of the methods laid down in this Defence Standard is to ensure that lots of an acceptable quality have a high probability of acceptance and that lots of inferior quality have as low a probability of acceptance as possible.
The fraction of nonconforming projectiles in a lot is used to define the quality of the lot and reflects the capability of the production process that generated it.
