Iron ores-Sampling and sample preparation procedures
 N JIS M 8702

Annotation

This Standard gives

a) the underlying theory

b) the basic principles for sampling and preparation of samples, and

c) the basic requirements for the design, installation and operation of sampling systems

for mechanical sampling, manual sampling and preparation of samples taken from a lot under transfer, to determine the chemical composition, moisture content, size distribution and other physical and metallurgical properties of the lot, except bulk density obtained using Method 2 of ISO 3852.

The methods specified in this Standard 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.

The methods are applicable to all iron ores, whether natural or processed (e.g. concentrates and agglomerates, such as pellets or sinters).

NOTE: The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows:

ISO/FDIS 3082: 2009 Iron ores-Sampling and sample preparation procedures (MOD)

The symbols which denote the degree of correspondence in the contents between JIS and the corresponding International Standard are IDT (identical), MOD (modified) and NEQ (not equivalent) according to ISO/lEC Guide 21-1.
