Foreword
GB/T 14984 "Ferroalloy term" is divided into three parts.
--- Part 1. Materials;
--- Part 2. Sampling and sample preparation;
--- Part 3. Screening.
This is Part 2.
The partial modification of the use of ISO 8954-2.1990 "Ferroalloys - Vocabulary - Part 2. Sampling and sample preparation" (in English).
This section according to ISO 8954-2.1990 redrafted. This section lists the control provisions of international standards and a clause in Appendix A
Lanbiao relevant technical differences have been incorporated into the text, and they are involved in terms of the margin of a single vertical line identified in Appendix B
It gives a list of the technical differences and the reasons for the reference.
This part of the international standard and also made the following editorial changes.
--- "This International Standard" be replaced by "this section";
"." --- With a decimal point instead of a comma as the decimal point, "";
--- Introduction of international standards and delete references.
This Part replaces GB /"Ferroalloy term" corresponding section T 14984-1994.
This section compared with the GB/T 14984-1994, mainly revised in the following areas.
--- Remove the general terms and ferroalloy product nomenclature;
--- Deleted the term ferroalloy screening;
--- Increasing the reduction of sub-term.
This section in Appendix A and Appendix B is an informative annex.
This part is proposed by the China Iron and Steel Association.
This part of pig iron and ferroalloy by the National Standardization Technical Committee.
