SECTION 5 Methods of sampling and analysis

Sampling plans for raw materials and finished products International methods of sampling should be used to ensure that valid sampling procedures are applied when feed is being tested for compliance to a particular standard or objective. The Codex General Guidelines on Sampling – CAC/GL 50-2004 (FAO/WHO, 2004) provides information to facili- tate the implementation of these goals (Box 21 ...

The raw coal primary sampler took periodic cross-stream cuts of the 4-in.* x 0 feed material, reduced it to 28 mesh x 0 in a hammermill crusher, and split it again through the secondary sampler. The sample collection vessel was left in place for 8 production hours to collect composites; the vessel was removed every 30 minutes during intensive study periods. The clean coal sampling system was ...

Standard Practice for Mechanical Sampling of Coal

1.2.1 Part A describes mechanical sampling procedures for coals (1) by size and condition of preparation (for example, mechanically cleaned coal or raw coal), and (2) by sampling characteristics. 1.2.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard.

Coal sampling - ScienceDirect

Raw coals have higher K s values and therefore more mass is required to achieve the same variance value for sampling clean coal. • For sampling around separators in a coal preparation plant, such as a dense medium cyclone to measure the efficiency of separation, the sample of feed will need to have a higher mass than the samples of product and reject streams. The precision of the efficiency ...
