BRIEF HISTORY
The IS0 Recommendation R 758, Method for the determination of density of liquids at
20 OC, was drawn up by Technical Committee ISO/TC 47, Chemistry, the Secretariat of which is
held by the Ente Nazionale Italian0 di Unificazione (UNI).
Work on this question by the Technical Committee began in 1956 and led, in 1962, to the
adoption of a Draft IS0 Recommendation.
In November 1963, this Draft IS0 Recommendation (No. 657) was circulated to all the IS0
Member Bodies for enquiry. It was approved, subject to a few modifications of an editorial nature, by
v
the following Member Bodies :
Australia HvwY Portugal
Austria India Romania
Belgium Israel Spain
Italy U.A.R.
Chile
Colombia Japan United Kingdom
Czechoslovakia Korea, Rep. of U.S.S.R.
France Netherlands Yugoslavia
Germany Poland
Two Member Bodies opposed the approval of the Draft :

The Draft IS0 Recommendation was then submitted by correspondence to the IS0 Council,
which decided, in June 1968, to accept it as an IS0 RECOMMENDATION.

IS0 Recommendation R 758 June 1968
METHOD FOR THE DETERMINATION OF DENSITY
OF LIQUIDS AT 20 "C
I. SCOPE
This IS0 Recommendation describes a reference method for the determination of the density of
liquids at 20 OC.
2. DEFINITION
The density at 20 "C of a material is the mass of unit volume of the material at a temperature of
20 OC. It is expressed in grammes per millilitre.
NOTE. - The millilitre (ml) is commonly used as a special name for the cubic centimetre (cm3). However, for
measurements of high accuracy* only the cub
