BRIEF HISTORY
The IS0 Recommendation R 115, Classification and composition of remelt ingots and pigs of unalloyed
aluminium, was drawn up by Technical Committee ISO/TC 79, ,L&ht metals and their alloys, the Secretariat of
which is held by the Association Franc&e de Normalisation (AFNOR).
Work on this question by the Technical Committee began in 1955 and led, in 1957, to the adoption of a
Draft IS0 Recommendation.
In January 1958, this Draft IS0 Recommendation (No. 202) was circulated to all the IS0 Member Bodies
for enquiry. It was approved by 25 Member Bodies and disapproved by 2 Member Bodies.
The Draft IS0 Recommendation was then submitted by correspondence to the IS0 Council which decided,
in July 1959, to accept it as an IS0 RECOMMENDATION.
BRIEF HISTORY CONCERNING THE 2nd EDITION
Working Group ISO/TC 79/WG 2 was entrusted, in 1964, by the Secretariat of Technical
Committee ISO/TC 79, Light metals and their alloys, with the study of the revision of IS0 Recom-
mendation R 115-1959. This work led, in 1966, to the adoption of a Draft Revision.
In August 1966, this Draft Revision (No. 1065) was circulated to all the IS0 Member Bodies
for enquiry. It was approved, subject to a few modifications of an editorial nature, by the following
Member Bodies :
Australia India
Switzerland
Austria Japan
Thailand
Belgium Korea, Rep. of
Turkey
Brazil Netherlands U.A.R.
. Canada Norway United Kingdom
Chile Poland U.S.A.
Czechoslovakia South Africa, U.S.S.R.
France Rep. of Yugoslavia
Germany
Spain
Hungary
Sweden
One Member Body opposed the approval of the Draft :
Italy
The new title, Classification and composition of unalloyed aluminium ingots for remelting,
supersedes the title of the first edition : Classification and composition of remelt ingots and pigs of
unalloyed aluminium; some amendments were made to the text.
The Draft Revision of IS0 Recommendation R 115-1959 was then submitted by correspon-
dence to the IS0 Council which decided, in March 1968, to accept it.
The present edition (2nd edition) supersedes the first edition of IS0 Recommendation R 115-

IS0 Recommendation
CLASSIFICATION AND COMPOSITION
OF UNALLOYED ALUMINIUM INGOTS FOR REMELTING
1. SCOPE
This IS0 Recommendation relates to the classification and composition of ingots for remelting of
primary and secondary unalloyed aluminium, excluding refined aluminium.
Ingots for remelting are classified according to their type (primary or secondary aluminium) and
graded according to their composition.
2. REQUIREMENTS
In all cases the type and grade should be agreed between the purchaser and the vendor and stated on
delivery.
3. CLASSIFICATION
The type is designated by the terms primary, secondary and refined aluminium which are defined
hereafter.
3.1 The term primaly applies to metal extracted by reduction from or by decomposition of an
aluminium compound and which has not been subjected to a
