本文件规定了一种通过参考标准测量仪器来确保体积密度（称为“每百升质量”）可追溯性的测试方法。每百升的质量对谷物具有商业重要性。有几种不同性能的仪器用于测量它。 本文件还规定了实验室或收集或储存筒仓中使用的国家标准仪器、二级标准仪器和测量仪器的性能要求。

This document specifies a test method for ensuring the traceability of bulk density, called "mass per hectolitre", measuring instruments through reference to standard measurement instruments. The mass per hectolitre is of commercial importance for grain cereals. Several types of instruments with varying performances exist for measuring it. This document also specifies the performances required of national standards instruments, secondary standards instruments, and measuring instruments used in laboratories or in collection or storage silos.
