Scope: When sampling in accordance with the method specified in ISO 3082:2002, the experimental method specified in this section is based on the stop-band sampling method of ISO 3082:2002 as a standard method to check the sampling deviation of iron ore. A check of the mechanical sampling system is recommended prior to deviation testing. For a sampling system that does not fully comply with ISO 3082:2002, deviations are generally undesirable. Therefore, when there is any objection to the main impact that does not meet the conditions of ISO 3082:2002, a deviation checking experiment can be done. If one party believes that under some specific conditions, the deviation may be large, then when using these conditions, the deviation test should usually be done. This section applies to the experimental method for checking the sampling deviation of iron ore.
