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

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-

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
