标准摘要
[中文适用范围]： ISO 11648 的这一部分规定了散装材料采样的应用和统计处理的一般原则。 它还提供了在调查质量特性平均值时估计必要方差以及检查精度和偏差的一般指导和示例。 此外，ISO 11648 的这一部分通过使用变差图和相关图提供了与串行数据统计分析相关的信息。 ISO 11648 的这一部分还定义了散装材料采样的基本术语和定义。 这些术语对于更好地理解采样技术以及更容易满足要求是必要的。 注：ISO 11648 第 2 部分适用于散装颗粒材料。 [外文原描述]： 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.
