This Standard's is necessary for height quality coal production from Ukrainian and for it taking place in the markets of the International and Europe. National Standard Technical Plan (NSTP) ISO 13909-1:2001 "Hard coal and coke – Mechanical sampling – Part 1 : General introduction" In this Standard taking part: - determinate total terms in the sphere sampling coal, antrazit and coke; - sampling and information for the text report about sampling; This Standard don’t take for determination lignites, brown coal, briquette from coal, manual sampling and sampling from mining. NSTP ISO 13909-2:2001 "Hard coal and coke – Mechanical sampling – Part 2: Coal – Sampling from moving steams" is determination procedure of the mechanical sampling and sampling from moving steams. This Standard don't take for sampling from heaps. NSTP ISO 13909-3:2001 "Hard coal and coke – Mechanical sampling – Part 3: Coal – Sampling from stationary lots" is determination procedure sampling from stationary lots, design of the sampling by analytic test, determination moisture, physics and chemical analysis. NSTP ISO 13909-4:2001 "Hard coal and coke – Mechanical sampling – Part 4: Preparation of test samples" is determination the continuous sampling, every sub-lot is sampled and the same sampling interval applies to all sub-lots. NSTP ISO 13909-7:2001 "Hard coal and coke – Mechanical sampling – Part 7: Methods for determining the precision of sampling, sample preparation and testing" is in all methods of sampling, sample preparation and analysis, error are incurred and the experimental results obtained from such methods for any given parameter will deviate from the true value of the parameter. Devise sampling scheme, assumption have to be made about the variability for a particular lot5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
