Kunststoffe - Flüssige Phenolharze - Konventionsverfahren zur Bestimmung der nichtflüchtigen Anteile (ISO 8618:1995)

Diese Internationale Norm legt ein Verfahren zur konventionellen Bestimmung der nichtflüchtigen Anteile von flüssigen Phenolharzen (Resolen, Novolak-Lösungen usw.) fest. Sie kann für die käuflichen Marktprodukte oder die Harze während der verschiedenen Stadien ihrer Verarbeitung verwendet werden. ANMERKUNG 1: Der Begriff "nichtflüchtige Anteile" bezieht sich bei Phenolharzen auf bestimmte definierte Versuchsbedingungen (siehe 4.2, Anmerkung 1). Die nach diesem Verfahren erzielten Ergebnisse können von denen bei der industriellen Anwendung der Harze abweichen.

Foreword
ISO (the International Organization for Standardization) is a worldwide
federation of national Standards bodies (ISO member bedies). 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 8618 was prepared by Technical Committee
lSO/TC 61, Plastics, Subcommittee SC 12, Thermosetting materjak.
This second edition cancels and replaces the first edition (ISO 8618:1987)
which has been revised to include an air circulation oven as an alternative
to the static convection oven.
Annex A forms an integral part of this International Standard.
