GB/T 10322.1-2023 Active

This document specifies the methods of mechanical sampling, manual sampling, and sample preparation during the transfer of a delivery batch to determine the chemical composition, moisture content, particle size distribution, and other physical and metallurgical properties (except for the determination of bulk density using ISO 3852 Method 2). It includes:
a) Basic theory;
b) Basic principles of sampling and sample preparation;
c) Basic requirements for the design, installation, and operation of sampling systems.
The methods specified in this document are applicable to the sampling of delivery batches during the loading and unloading processes of belt conveyors and other ore transport equipment. Belt conveyors and other ore transport equipment can be equipped with mechanical samplers, and manual sampling can also be safely conducted on these devices.
These methods are suitable for all iron ores, whether natural or processed (such as fine-powdered ores and artificial lump ores like pellet ores or sintered ores).
