基于验收编号的常规属性抽样不再可取，当检验过程中遇到一些允许数量的不合格时，允许验收批次。此外，强调批次公差缺陷百分比（LTPD）值或MIL-STD-105的限制质量部分。以不合格百分比衡量质量水平。虽然并非不正确，但已被百万分之一（PPM）的质量水平测量所取代。因此，本标准解决了可以增加MIL-STD-105的抽样计划的需要，并解决质量（百万分之几范围内的不合格水平）。本文件未解决轻微不合格，这些不合格被定义为不可能实质性降低产品单元用于预期用途的可用性的不合格。

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.
