Gaz de pétrole liquéfiés - Détermination des résidus huileux - Méthode à haute température (ISO 13757:1996)
La présente Norme internationale prescrit une procédure pour la détermination des résidus pouvant être contenus dans les gaz de pétrole liquéfiés (GPL), subsistant après évaporation à 105 °C. Ces résidus, dénommés «résidus huileux», correspondent à tous les produits piégés dans les systèmes de vaporisation qui sont susceptibles d'être soumis à un apport calorifique externe supérieur à l'évaporation ambiante.

Foreword
ISO (the International Organization for Standardization) is a worldwide
federation of national Standards bodies (ISO member bodies). The work
of preparing International Standards is normally carried out through ISO
technical committees. Esch 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. ISO
collaborates closely with the International Electrotechnical Commission
(1 EC) 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 ISO 13757 was prepared by Technical Committee
ISO/TC 28, Petroleum products and lubrkan ts.
Annex A of this International Standard is for information only.
