Iron ore Health and Safety Inspection Technical Specifications
Part 1. Sampling manual method
1 Scope
This section provides the iron ore manual sampling methods.
This section applies to natural iron ore and iron ore processing to obtain particle size distribution, moisture content, chemical composition and physical properties measurement
sample.
These methods apply from the conveyor belt, railway wagons, containers (including trucks), to take the ship and stockpile ore samples.

3 Terms and Definitions
GB/T 20565 and GB/T 2007.1 ~ 2007.7 establishes the terms and definitions apply to this section.
4 sampling scheme
Sampling program are as follows.
a) verify that the sampling consignment or part consignment;
b) determine the maximum size of the consignment;
c) determining the amount of increment to the maximum size;
d) determining the type of consignment of quality fluctuations;
e) use of systematic sampling and stratified sampling when determining the minimum number of samples from parts of the consignment to be taken; when two samples used, starting with all the cross
Batch selected goods prescribed truck or container, and then choose from a number of these wagons take point increments;
f) the system sampling and stratified sampling or measurement method selected interval truck or container, it is determined to take part sample interval;
g) to determine the sampling points and take parts of such methods;
h) during the whole process of handling the consignment, take sample parts have almost the same quality.
