Is applicable to the mechanical sampling of coke from moving streams for physical testing, general analysis and the determination of total moisture in the coke. Methods for the preparation of these samples are also described. Apart from the taking of primary increments and primary increment division, describes the on-line single stage crushing and division of the moisture sample. Methods for checking overall precision of sampling, testing for bias and general statistical methods are included in annexes A, B and C respectively.
