The MAR serves as a guide for the maximum allowable magnitude of the average range of thesample when using plans for the double speci cation limit case, based on the average range. The matching is sufficient to allow inspection under either standard for stated AQLs and inspection levels with reasonably equivalent protection.

It is organized into five parts and is designed to help leaders and organization architects understand: The MSD serves as a guidefor the maximum allowable magnitude of the estimate of lot standard deviation when using plans for the double speci ca-tion limit case, based on the standard deviation.

All AQL values are in percent nonconforming. Also available in soft cover.
