标准范围
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.
