Es cuestión de saber un poquito de la historia de los standares, en España tenemos la UNE, que a fin y a cuentas aplica ISOs y al principio adaptaba DINs y british (no me acuerdo del acrónimo).
Por cierto ISO es International Organization for Standardization www.iso.org
donde podrás leer este artículo http://www.iso.org/iso/en/commcentre/isocafe/link/papersizes.html donde te he puesto en negrita y subrayado lo que concierne a este punto.
Tracing the history of paper sizes
The development of ISO paper formats now used in most parts of the world is a very interesting example of one man being able to set the foundation for an International Standard.Dr. Walter Porstmann, a Berlin engineer, suggested a mathematical basis of the format series - 1 to the square root of 2 as the relationship between the width and the length. The idea of a mathematical basis for paper sizes, however, was not new. In addition to having been previously recommended by George Lichtenberg at the end of the 18th century, sizes corresponding to a number of the A-formats were also used, though briefly, during the French revolutionary period.
Another attempt to take up this idea of a mathematic basis was made at the end of the 19th century by the chemist and philosopher (and unwilling mentor to Porstmann), Wilhelm Ostwald, who suggested the "World Format". His size series proceeded from the smallest size of 1 cm: 1,41 cm and increased by successive doubling (1,41 x 2, 2 x 2,83, 2,83 x 4 etc.). The "World Format" did not get off the ground.
According to Porstmann, this linear connection to the metric system was not satisfactory - any line of a surface could be taken as the point of reference. Porstmann's notion was that the reference point should be one of area, and after some experimenting with 1 cm² as the basis of the format series, he finally hit on the square metre as the starting point - A0, the remaining formats being obtained by halving. This work - and work on standardizing the formats of technical drawings - was conducted by the Standards Committee of German Industry (as DIN was then called) and published in August 1922 as DIN 476.
The use of the formats (A, B, C, D) was supported by a number of large corporations as well as by government agencies and local authorities. By the end of the 1920s, for example, their use was widespread in Germany. Whereas abroad, Belgium was the first country to adopt the formats in 1924, followed by the Netherlands a year later. The Scandinavian countries followed suit (by 1930). The Soviet Union adopted them in 1934, Italy in 1939, a number of South American countries in the early 1940s, Austria in 1947, Japan in 1951, India in 1957, the UK in 1959, Mexico in 1965, France in 1967, Greece in 1970, Australia in 1974 and Kuwait in 1975 .and the list goes on.
In 1961, ISO published the recommendation ISO/R 216, Trimmed sizes of writing paper and certain classes of printed matter, thereby adopting the DIN A-format This recommendation was then superseded in 1975 with the publication of an International Standard ISO 216, Writing paper and certain classes of printed matter - Trimmed sizes - A and B series, which as the title suggests, incorporates the format series A and B, but not C. (differences only in the permissible deviations, which were slightly larger in the ISO standard). By 1977 it was established that the ISO formats were being used in 88 of the 148 countries investigated.
Note: Most of this information comes from a booklet published by DIN, Deutsches Institut für Normung, ISO member body for Germany, entitled DIN-Format A4 - A successful system endangered (available in German).
