La CEI 60068-2-55:2013 fournit une procédure normalisée permettant de déterminer l'aptitude d'un spécimen à résister à des sévérités spécifiées de rebondissement, lorsqu'il est transporté par exemple sans arrimage sur des véhicules à roues. Cette deuxième édition annule et remplace la première édition, publiée en 1987. Elle constitue une révision technique. Les modifications principales par rapport à l'édition précédente sont les suivantes: Cette nouvelle édition prévoit des essais de chargement sans arrimage dans un sens plus général. L'essai n'est plus conduit à l'aide d'un appareil spécial d'essai mais permet d'utiliser tout matériel approprié tel que les tables vibrantes électrodynamiques ou servo-hydrauliques. De plus, les vibrations sinusoïdales et aléatoires peuvent être utilisées. Les mouvements antérieurs de la table de rotation sont inclus dans l'Annexe A à titre de méthodes historiques.
Cette publication doit être lue conjointement avec la CEI 60068-1:1988.

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work of
preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for which
a technical committee has been established has the right to be represented
on that committee. International organizations, governmental and non-
governmental, in liaison with ISO, also take part in the work. IS0 collab-
orates closely with the International Electrotechnical Commission (IEC) on
all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard IS0 10283 was prepared by Technical Committee

Introduction
It is well-known fact that, due to the production methods used, all the commercial isocyanate resins
named in this standard contain a certain amount of volatile monomeric isocyanates. This amount is
generally less than 0,5 % relative to the resin as supplied. In view of the regulations relating to the
handling of hazardous substances, it has become a matter of special concern that a generally accepted
and applicable method of determination should be available. This standard is not intended to present a
method suitable for the analytical determination of volatile isocyanates in any form and in any quantity.
The standard specifies a method confined to determining the amounts of volatile isocyanates which
occur in practice in isocyanate resins, namely about 0,l % to 0,4 %. A further objective of the standard
was to develop a method for determining with adequate accuracy as many as possible of the monomeric
isocyanates which occur in isocyanate resins. It detects the principle isocyanates, namely toluene
diisocyanate (TDI), hexamethylene diisocyanate (HDI), diphenylmethane diisocyanate (MDI) and
isophorone diisocyanate (IPDI), and is a method considered by industry, authorities and institutes alike
to be the state of the art.

4 Principle
The content of monomeric diisocyanate in isocyanate resins is determined by gas chromatography,
using tetradecane or, in the case of diisocyanates of low volatility, anthracene as the internal standard.
5 Reagents
During the analysis, use only reagents of recognized analytical grade.
5.1 Ethyl acetate, anhydrous (dried with 0,5 nm molecular sieve) and ethanol-free (ethanol content
< 200 ppm).
5.2 Tetradecane or anthracene
5.3 Toluene diisocyanate (isomeric mixture)
5.4 Hexamethylene diisocyanate
5.5 lsophorone diisocyanate (isomeric mixture)
5.6 Diphenylmethane diisocyanate
5.7 Solution of internal standard
Weigh approximately 1,4 g of tetradecane or anthracene to the nearest 0,l mg into a 1000 ml volumetric
flask and make up to the mark with ethyl acetate (5.1).
