标准范围

ISO 14560:2004规定，对于以百万分之不合格项表示的质量水平，评估单个实体（如一批）质量水平的程序，以及当生产过程处于统计控制中时，根据多个样本的证据评估过程质量水平的程序。还规定了在选择合适的抽样计划时使用该信息的程序，以验证给定批次的质量水平不超过规定的极限质量水平（LQL）。对于之前没有可用样本数据的情况，给出了在选择计划时假定过程质量水平的指南。

ISO 14560:2004 specifies, for quality levels expressed as nonconforming items per million items, procedures for estimating the quality level of a single entity (e.g. a lot) and, when the production process is in statistical control, for estimating the process quality level based on evidence from several samples. Procedures are also specified for using this information when selecting a suitable sampling plan so as to verify that the quality level of a given lot does not exceed a stated limiting quality level (LQL). For the case where no prior sample data is available, guidance is given for presuming a process quality level in selecting a plan.
