本SAE航空航天推荐实践(ARP)的目的是确保批次中验证的每个产品特性的一致性，而无需维护以前批次的信息。ARP9013/1规定了分离批次的产品验收系统。例如，隔离批次采样避免了跟踪以前在MIL-STD-105中使用和目前在ANSI/ASQC Z1.4中使用的正常、严格和降低的采样水平。由于这些切换规则为产品质量提供了重要的长期保护，因此这些隔离的批次表以其他方式取代了这种保护。

The purpose of this SAE Aerospace Recommended Practice (ARP) is to ensure conformance for each product characteristic being verified in a lot, without maintaining information from previous lots. ARP9013/1 specifies a product acceptance system for isolated lots. For example, isolated lot sampling avoids keeping track of the normal, tightened, and reduced levels of sampling formerly used in MIL-STD-105 and currently used in ANSI/ASQC Z1.4. Because those switching rules provided significant long-term protection for product quality, these isolated lot tables replace that protection in other ways.
