This Internation

23、 brief guide to the layout of this document. The general theoretical basis on which coke sampling is based is to a large extent similar to that for coal. This subject is extensively discussed in IS0 1988 and the relevant sections are therefore not reproduced. Reference should also be made to IS0 198
24、8 for details of the methods for checking : a) the precision of sampling by means of replicate sampling; b) the error of sample preparation; c) the presence of bias. As automatic sampling apparatus will, so far as is known, be common to both coal and coke, reference should also be made to IS0 1988 f
