Доопрацювання проектів стандартів з урахуванням зауважень погоджувальних організацій, погодження проектів і подання їх на експертизу Head Skliar, Registration Date 10-12-2008 Organization Ukraine Technical Committee for Standardization TC 92 "Coal and products of its processing" popup.description2 National standard DSTU ISO 13909-8 “Bituminous coal, hard coal and coke. Mechanized sampling” has been developed. Part 8. Methods of systematic error determination are inalienable part of DSTU ISO 13909 standard series and describe systematic error determination methods of mechanized sampling. Standard introduction will allow to promote accuracy of the mechanized fuel sampling, settle the relations between a supplier and consumer, evaluate quality of fuel maximally objectively National standard DSTU ISO 8858-2 “Bituminous coal and hard coal. Method of froth flotation test” has been developed. Part 2 – A successive test describes the procedure for more complete determination of coal floatation descriptions by the equipment and basic procedures which are resulted in DSTU ISO 8858-1:2004. The purpose of this extended procedure is to get data similar to the curve of sediment/emerging on which the division of density is founded. Received data is expresses as dependence of output on an ash-content. This information is used for limit determinations during while improving coal by froth flotation. Standard introduction will allow setting technological mode of flotation on coal-concentrating plants and estimating the work of floatation divisions. National standard DSTU ISO 8858-3 “Bituminous coal and hard coal. Method of froth flotation test has been developed. Part 3. A test with restrictions-remove can be applied for coal of different coal rank and gives the coal conduct behavior method during floatation and also facilitates an information exchange on the process features. It describes methods of different terms of test application for proper coal conduct determination in the process of floatation. The use of this method provides comparison method of floatation characteristics. Due to high producibility of results, tests give the reliable method of floatation characteristics comparison of different coal tests. This method gives basis of test parameters varying for the research of any special floatation characteristics5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
