BRIEF HISTORY
The IS0 Recommendation R 62, Plastics - Determination of Water
Absorption, was prepared by Technical Committee ISO/TC 61, Plastics, the
Secretariat of which is held by the American Standards Association, Incor-
porated (ASA).
This question was among the first subjects to be considered by the Technical
Committee, which decided, at its first meeting, held in New York, in September
1951, to assign the development thereof to its Working Group No. 5, Physical
Chemical Properlies, under the leadership of the United Kingdom.
\
At the second meeting of ISO/TC 61, held in Turin, in October 1952, the
Working Group reached tentative agreement on all the points involved and a
draft was worked out, which was distributed by the Secretariat, in June 1953,
to the members of the Technical Committee, as a first draft proposal of an IS0
Recommendation.
Having taken into account the observations made, the Secretariat prepared
a second draft proposal, which was adopted as a Draft IS0 Recommendation,
subject to some amendments, at the fourth meeting of the Technical Committee,
held at Brighton, in October 1954.
On 31 December 1955, the Draft IS0 Recommendation was circulated to
all IS0 Member Bodies and, some amendments having been taken into con-
sideration, it was approved by the following 27 Member Bodies (out of a total
of 37):
Australia India Portugal
Belgium Ireland Spain
Sweden
Bulgaria Israel
Chile Italy Turkey
Czechoslovakia Mexico Union of South Africa
Netherlands United Kingdom
"Denmark
Finland New Zealand U.S.A.
Germany Pakistan U.S.S.H.
Poland Yugoslavia
*Greece
No Member Body opposed approval of the Draft.
The Draft IS0 Recommendation was then submitted, by correspondence,
1958, to accept it as an IS0
-to the IS0 Council, which decided, in April
RECOMMENDATION.
* These Member Bodies stated that they had no objection to the Draft being approved.

AMENDMENT 1 -JUNE 1965
TO IS0 RECOMMENDATION R 62 1958
Amendment 1
to IS0 Recommendation R 62-1958
PLASTICS
DETERMINATION OF WATER ABSORPTION
(1) paragraph 1.1 is replaced by the following new paragraphs 1.1, 1.2 and 1.3:
1.1 This method of test describes the conventional procedure for determining the weight of
water absorbed by a moulded test specimen or one machined to shape from sheet, rod or
tube, as a result of immersion in water for a specified time and at a specified temperature.
1.2 The water absorption values of different plastics materials may give an indication of their
comparative behaviours in moist conditions but do not represent the maximum amounts
of water that can be absorbed. The absorption of water can affect the dimensions and the
electrical and the mechanical properties of materials.
1.3 The presence in a material of water-soluble matter will, if no allowance is made, give rise
to an incorrect value of water absorption and hence may give a misleading indication of
the behaviour of the material under moist conditions. For this reason a modified method
B) is included describing the procedure to be adopted when a significant amount
(Procedure
of water-soluble matter is known to be present.
(2) paragraph 1.2 becomes paragraph 1.4.
BRIEF HISTORY
At the plenary meeting held by Technical Committee ISO/TC 61 in Turin in 1961, Working
Group WG 5 suggested the modification of Section 1-Purpose, of IS0 Recommendation R 62
along lines indicated in the above Amendment. Although this is purely and simply an editorial
modification, it was felt best that it should be made, in order to explain more fully the limi-
tations of the test if no consideration is given to the presence of water-soluble matter in a
material, as well as to provide a fuller explanation of the reasons why Procedure B should
be used where significant amounts of water-soluble matter are known to be present. The
Members of the Technical Committee unanimously adopted these editorial modificati

HISTORIQUE
La Recommandation ISO/R 64, Tubes en acier - Diamdtres extérieurs,
a été élaborée par le Comité Technique ISO/TC 5, Tuyauteries et raccords,
dont le Secrétariat est assumé par l’Association Suisse de Normalisation (SNV).
Au cours de sa première réunion, tenue Q Zurich, en mai 1951, le Comité
Technique décida de normaliser les diamètres extérieurs des tubes en acier
sur la base des travaux de l’ancienne Fédération Internationale des Associations
Nationales de Normalisation (ISA) et des normes existantes, tant du point
de vue de la situation actuelle que du développement à prévoir dans la fabrica-
tion des tubes en acier. Les travaux furent confiés au Sous-Comité ISO/TC 5/SC 1,
Tubes de la série gaz et aufres tubes en acier.
Le Sous-Comité 1 se réunit A Zurich, en octobre 1951 et en mai 1952,
et établit une liste de diamètres basée sur les tubes pouvant être filetés, jusqu’au
diamètre extérieur de 139,7 mm (ou de 5 1/2 in), selon la Recommandation
ISO/R 7, et au-dessus de cette dimension, selon les normes américaines
ASA B2.1-1945, API 5A et API 5L.
Le Sous-Comité poursuivit ses études A Zurich, en novembre 1953, à
Düsseldorf, en juin 1954, A Paris, en novembre 1954, et, en groupe de travail,
A Londres, en février 1955, et prépara un premier avant-projet. Après plusieurs
mises au point, un nouveau document fut adopt6 par le Sous-Comité Q sa réunion
de Rigi-Kaltbad, en juillet 1956, et par le Comité Technique, comme Projet
de Recommandation ISO.
En date du 10 avril 1957, le Projet de Recommandation IS0 fut soumis
à tous les Comités Membres de I’ISO et approuvé par 23 Comités Membres sur
un total de 38:
Allemagne Espagne *Irlande Royaume-Uni
*Australie Finlande Israel Suède
Autriche France Italie Suisse
Belgique *Grèce Nouvelle-Zélande Tchécoslovaquie
