SAE EIA585

Conventional attribute sampling based upon acceptance numbers that permit acceptance of a lot when some allowable number of nonconformances are encountered during inspection are no longer desirable. In addition, emphasis to the Lot Tolerance Percent Defective (LTPD) value or the Limiting Quality Portection of MIL-STD-105. Measuring quality levels in percent nonconforming. although not incorrect, has been replaced with quality levels measures in part per million (PPM). As a result, this standard addresses the need for sampling plans that can augment MIL-STD-105 are based upon a zero acceptance number, and address quality (nonconformance levels in the parts per million range. This document does not address minor nonconformances, which are defines as nonconformances that are not likely to reduce materially the usability of the unit of product for its intended purpose.
