BRIEF HISTORY
The IS0 Recommendation R 18 1 1, Chemical arialysis of copper arrd copper alloys - Sampling of copper
refinery shapes, was drawn up by Technical Committee ISO/TC 26, Copper and copper alloys, the Secretariat of
which is held by the Detuscher Normenausschuss (DNA).
Work on this question led to the adoption of Draft IS0 Recommendation No. 181 1, which was circulated
to all the IS0 Member Bodies for enquiry in March 1969. It was approved, subject to a few modifications of an
editorial nature, by the following Member Bodies :
South Africa, Rep. of
Australia India
Iran Spain
Belgium
Brazil Israel Sweden
Italy Switzerland
Canada
Chile Korea, Rep. of Turkey
Czechoslovakia Netherlands U.A.R.
France New Zealand United Kingdom
Germany Norway U.S.A.
Greece Peru Yugoslavia
Hungary Poland
The following Member Body opposed the approval of the Draft
Finland
This Draft IS0 Recommendation was then submitted by correspondence to the IS0 Council, which decided
to accept it as an IS0 RECOMMENDATION.

IS0 Recommendation R 1811 August 197 1
CHEMICAL ANALYSIS OF COPPER AND COPPER ALLOYS
SAMPLING OF COPPER REFINERY SHAPES
1. SCOPE
This IS0 Recommendation relates to the preparation of samples of copper refinery shapes to determine whether
the chemical composition of the latter complies with requirements as laid down in corresponding IS0 Recom-
mendations.
The refinery shapes covered in this IS0 Recommendation are : cathodes, wire bars, cakes, slabs, billets, ingots
and ingot bars.
2. CONSIGNMENTS AND LOTS
For the determination of the copper content, consignments up to a total mass of about 300 tons should be
considered as a single lot, provided that the whole of the consignment is of the same charge and consists of
uniform shapes. Consignments exceeding 300 tons in total mass should be divided into lots of approximately
equal size.
If a consignment consists of several charges and/or different shapes, the consignment should be divided into
lots according to charges and shapes.
The size of the lots depends on the charges and shapes forming the consignment concerned and/or on the
arrangements made between the interested parties.
3. PROCEDURE
3. i Conventional procedure
For sampling, take three pieces as gross samples from each of the lots (charges, shapes) according to
section 2 unless otherwise agreed between the interested parties.
Remove surface contamination, if any, from the three pieces, and also remove any surface oxide layer from
those areas where samples are to be taken. Drill holes completely through each piece, or, if the pieces are
too t
