标准范围

ISO 24153:2009定义了随机抽样和随机化程序。提供了几种方法，包括基于机械设备的方法、随机数表和便携式计算机算法。当法规、合同或其他标准要求使用随机抽样或随机化时，ISO 24153:2009适用。这些方法适用于以下情况:a） 分批提交检验的离散单元的验收抽样，b） 为调查目的进行抽样，c） 质量管理体系结果的审核，以及d） 选择实验单元，为其分配治疗，并在进行设计实验时确定评估顺序。在质量管理人员或监管机构要求的情况下，还包括有助于对随机抽样或随机化结果进行审计或其他外部审查的信息。ISO 24153:2009未就任何特定实验情况下使用的适当随机抽样或随机化程序提供指导，也未就可能的抽样策略选择或样本量确定提供指导。应参考其他ISO国际标准（如ISO 2859、ISO 3951、ISO 8422、ISO 8423、ISO 13448、ISO 14560、ISO 18414、ISO 21247和ISO 11648）或权威参考文献，以获取此类领域的指导。

ISO 24153:2009 defines procedures for random sampling and randomization. Several methods are provided, including approaches based on mechanical devices, tables of random numbers, and portable computer algorithms.ISO 24153:2009 is applicable whenever a regulation, contract, or other standard requires random sampling or randomization to be used. The methods are applicable to such situations asa) acceptance sampling of discrete units presented for inspection in lots,b) sampling for survey purposes,c) auditing of quality management system results, andd) selecting experimental units, allocating treatments to them, and determining evaluation order in the conduct of designed experiments.Information is also included to facilitate auditing or other external review of random sampling or randomization results where this is required by quality management personnel or regulatory bodies.ISO 24153:2009 does not provide guidance as to the appropriate random sampling or randomization procedures to be used for any particular experimental situation or give guidance with respect to possible sampling strategy selection or sample size determination. Other ISO International Standards (such as ISO 2859, ISO 3951, ISO 8422, ISO 8423, ISO 13448, ISO 14560, ISO 18414, ISO 21247 and ISO 11648) or authoritative references should be consulted for guidance in such areas.
