Petroleum products - Determination of carbon residue - Micro method (ISO 10370:1993)
The principle of the method specified is placing a weighed aliquot of the oil sample in a glas vial, heating it to 500 °C under an inert (nitrogen) gas stream in a controlled manner for a specific time, sweeping away the volatiles formed during the reactions by the inert gas, weighing the carbonaceous residue remaining. The method may be used to determine amounts of carbon residues in the range of 0,10 % (m/m) to 30,0 % (m/m), left after evaporation and pyrolysis. On materials, which may yield a carbon residue below 0,10 % (m/m), a 10 % (V/V) distillation residue is prepared by the procedure described in ISO 3405 before analysis.

La CEI 61000-4-3:2006+A1:2007+A2:2010 traite de l'immunité des matériels électriques et électroniques à l'énergie électromagnétique rayonnée. Elle définit les niveaux d'essai et les procédures d'essai nécessaires. Cette norme a pour objet d'établir une référence commune d'évaluation des performances des matériels électriques et électroniques soumis à des champs électromagnétiques aux fréquences radioélectriques. La méthode d'essai documentée dans cette partie de la CEI 61000 décrit une méthode cohérente afin d'évaluer l'immunité d'un équipement ou d'un système vis-à-vis d'un phénomène défini. La présente partie traite des essais d'immunité relatifs à la protection contre les champs électromagnétiques RF de quelque source qu'ils soient. Des considérations particulières sont consacrées à la protection contre les émissions aux fréquences radioélectriques des radiotéléphones numériques et d'autres dispositifs d'émission RF.

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
(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 ISO 10370 was prepared by Technical Committee
lSO/TC 28, Petroleum products and lubricants.
Annexes A and B of this International Standard are for information only.
