Preface
Goals, basic principles and main procedure of works on interstate standardization have been established in GOST 1.0−92 «interstate standardization system. Basic provisions» and GOST 1.2−2009 «interstate standardization system. Interstate standards, rules and recommendations on interstate standardization. Rules of development, adoption, application, renewal and cancellation"
Data on standard
1 DEVELOPED by the Technical Committee for standardization TC 368 «Copper"
2 recorded by the Interstate technical Committee for standardization MTK 503 «Copper"
3 ACCEPTED by the Interstate Council for standardization, Metrology and certification (minutes of 25 June 2014 No. 45−2014)
The adoption voted:
4 by Order of the Federal Agency for technical regulation and Metrology from August 1, 2014 No. 865-St inter-state standard GOST 859−2014 introduced as a national standard of the Russian Federation from July 1, 2015.
5 REPLACE GOST 859−2001
Information about the changes to this standard is published in the annual reference index «National standards», and the text changes and amendments — in monthly information index «National standards». In case of revision (replacement) or cancellation of this standard a notification will be published in the monthly information index «National standards». Relevant information, notification and lyrics are also posted in the information system of General use — on the official website of the Federal Agency for technical regulation and Metrology on the Internet
1 Scope
This standard applies to copper, made in the form of cathodes, as well as cast and deformed semi-finished products.
2 Normative references
This standard uses the regulatory references to the following international standards:
GOST 9717.2−82 Copper. Method of spectral analysis on a metal standard samples with photographic registration of spectrum
GOST 9717.3−82 Copper. Method of spectral analysis of oxide standard specimens
GOST 13938.11−78 Copper. Method for the determination of arsenic
GOST 13938.13−93 Copper. Methods for determination of oxygen
GOST 27981.1−88 Copper of high purity. Methods of atomic-spectral analysis
GOST 27981.2−88 Copper of high purity. Method of chemical-atomic-emission analysis
GOST 27981.5−88 Copper of high purity. Photometric methods of analysis
GOST 27981.6−88 Copper of high purity. Polarographic methods of analysis
GOST 31382−2009 Copper. Methods of analysis
ST SEV 543−77 Number. Record rules and rounding
Note — When using this standard appropriate to test the effect of reference standards for the sign «National standards» drawn up as of January 1 of the current year and related information signs, published in the current year. If the reference standard is replaced (changed), when using this standard should be guided by replacing (amended) standard. If the reference standard is cancelled without replacement, then the situation in which the given link applies to the extent that does not affect this link.
3 Technical requirements
3.1 Chemical composition of copper shall be those specified in tables 1 and 2. In accounting and documentation it is allowed to specify the mass fraction of impurities in copper of all grades in grams per tonne (parts per million, ppm). The consistent copper grades according to this standard and standards [1] and [2] are given in Appendix A.
3.2 Mass fraction of chemical elements not listed in tables 1 and 2, it is determined by agreement of the parties in accordance with the contract.
3.3 Requirements for the physical properties of copper, electrical resistivity, spiral elongation (ability to recrystallization with preset parameters of heat treatment) and mechanical properties set in the standards for specific types of products and/or by agreement of the parties in the contract.
3.4 Chemical composition of copper depending on brands determine
13938.11 GOST, GOST 13938.13, 9717.2 GOST, GOST 9717.3, GOST 27981.1,
27981.2 GOST, GOST 27981.5, 27981.6 GOST, GOST 31382.
The use of other methods of analysis, accuracy is not inferior to the above.
Arbitration methods of analysis point in the standards for specific types of products.
3.5 the results of the analysis of each element are rounded according to the rounding rules established ST SEV 543, to the number of digits set in tables 1 and 2.
