BRIEF HISTORY
The IS0 Recommendation R 197, CZass$cation of Coppers, was drawn up by Technical
Committee ISO/TC 26, Copper and Copper Alloys, the Secretariat of which was held by
the American Standards Association, Inc. (ASA) until June 1960 and, since this date, by
the Deutscher Normenausschuss (DNA).
In preparation for the first meeting of ISO/TC 26, held in Stockholm, in June 1955,
the Secretariat presented a draft proposal concerning the subject of this IS0 Recommenda-
tion. This document was examined during the meeting and then turned over to a Working
Group for thorough study; the latter proposed a number of changes. The document
.
was revised accordingly, and was approved by the Technical Committee, in plenary
session, as a Draft IS0 proposal. In November 1957, this draft proposal was circulated
for vote by letter ballot to the members of the Technical Committee.
During its second meeting, held in Harrogate, in June 1958, the Technical Committee
examined the results of the vote and the comments received, and prepared a revised draft
proposal taking into account the amendments presented by various Member Bodies. On
this basis, after full discussion, the draft proposal revised in this way was approved as a
Draft IS0 Recommendation.
On 26 June 1959, the Draft IS0 Recommendation (No. 312) was distributed to all
the IS0 Member Bodies and was approved by the following Member Bodies:
Australia Ireland Portugal
Belgium Israel Romania
Burma Italy Spain
Canada Japan Sweden
Chile Mexico Switzerland
*-
Finland Netherlands Turkey
Germany New Zealand United Kingdom
Greece Norway U.S.A.
India Poland Yugoslavia
One Member Body opposed the approval of the Draft : France.
The Draft IS0 Recommendation was then submitted by correspondence to the IS0
Council, which decided, in May 1961, to accept it as an IS0 RECOMMENDATION.

IS0 Recommendation R 197 May 1961
CLASSIFICATION OF COPPERS
1. SCOPE
This IS0 Recommendation contains a classification of the various types of coppers currently
available in cast refinery shapes and wrought products in commercial quantities. It is not a
specification for the various types.
2. BASIS OF CLASSIFICATION
The table shows the refinery shapes currently produced. In each type the specific coppers
2.1
are not necessarily available in a complete range of sizes in the form shown, nor from any
one supplier in all forms.
2.2 The specifications indicated for cast refinery shapes and for wrought copper products
may cover more than one of the types given in the table or may include only part of the
range covered by one of the types shown in the classification.
3. DEFINITIONS
The definitions which appear in Appendix 1 to this classification cover the terms used in designating
the various types of coppers, but do not include definitions of the types of coppers as such.
The definitions which appear in Appendix 2 are also given for the various forms of refinery
shapes.
