This document was prepared by Technical Committee ISO/TC 102, Iron ore and direct reduced iron, Subcommittee SC 1, Sampling. This fifth edition cancels and replaces the fourth edition ( ISO 3082:2009 ), which has been technically revised.

The methods specified in this document are applicable to both the loading and discharging of a lot by means of belt conveyors and other ore-handling equipment to which a mechanical sampler can be installed or where manual sampling can safely be conducted.

The methods specified in this ISO 3082:2009 are applicable to both the loading and discharging of a lot by means of belt conveyors and other ore-handling equipment to which a mechanical sampler may be installed or where manual sampling may safely be conducted.

This document specifies the methods to be employed for determination of size distributions by sieving of iron ore and direct reduced iron (excluding briquetted iron), utilizing sieves having aperture sizes of 36 µm or larger.

ISO 7764:2006 specifies a method for the preparation of predried test samples of natural iron ores, and iron ore concentrates and agglomerates, including sinter products, which are to be used for the determination of analytical values of constituents on a dry basis.

This document specifies a method for the determination of the moisture content of a lot of iron ore. This method is applicable to all iron ores, whether natural or processed.

Specifies two methods for the determination of 0,05 % (m/m) to 6 % (m/m) of hygroscopic moisture content in test samples.
