ISO 11648-1:2002确立了散装材料取样应用和统计处理的一般原则。它还为在调查质量特征的平均值时估计必要的方差、检查精度和偏差提供了一般指导和示例。此外,ISO 11648-1:2002的本部分通过使用变异函数和相关图给出了与序列数据统计分析有关的信息。
ISO 11648-1:2002还定义了散装材料取样的基本术语和定义。这些术语对于更好地理解取样技术以及更容易满足要求是必要的。
ISO 11648-1:2002 establishes the general principles for the application and statistical treatment of the sampling of bulk materials. It also provides general guidance and examples for estimating necessary variances and checking precision and bias when the average value of a quality characteristic is investigated. Furthermore, this part of ISO 11648-1:2002 gives information relating to the statistical analyses of serial data, by the use of variograms and correlograms.
ISO 11648-1:2002 also defines the basic terms with definitions for the sampling of bulk materials. These terms are necessary for providing a better understanding of sampling techniques as well as making it easier to fulfil requirements.
