Scope
This standard specifies the method of taking chromite ore samples at the delivery and reception locations. This method is applicable to the sampling of all natural chromite ores or processed chromite ores by manual and mechanical methods. Appendix A stipulates the procedure for taking samples of block-shaped chromite ores with a particle size of >100 mm by hammer and shovel sampling methods.
