Kunststoffe - Bestimmung der Viskosität von Polymeren in verdünnter Lösung unter Verwendung von Kapillarviskosimetern - Teil 2: Vinylchlorid-Polymere (ISO 1628-2:1998)

Dieser Teil von ISO 1628 definiert Bedingungen zur Bestimmung der reduzierten Viskosität (auch bekannt unter dem Begriff Viskositätszahl) und des K-Wertes von VC-Polymeren. Er findet Anwendung für Polymere in pulvriger Form, die aus Homopolymeren des Monomers Vinylchlorid und Co- oder Terpolymeren etc. von Vinylchlorid mit einem oder mehreren anderen Monomeren bestehen, wobei aber Vinylchlorid den Hauptbestandteil darstellt. Die Polymere können kleine Mengen nicht polymerisierter Substanzen (z.B. Emulgatoren oder Suspensionshilfsmittel, Katalysatorreste etc.) sowie anderer Substanzen enthalten.

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. 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. 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 1628-2 was prepared by Technical Committee
ISO/TC 61, Plastics, Subcommittee 9, Thermoplastic materials.
This second edition cancels and replaces the first edition
(ISO 1628-2:1988) which has been modified to include:
— the determination of the K-value;
— a limit on the volatile-matter content of resins that can be tested using
this part of ISO 1628;
— revised viscometer specifications;
— a reference viscometer;
— a precision statement.
ISO 1628 consists of the following parts, under the general title Plastics —
Determination of the viscosity of polymers in dilute solution using capillary
viscometers:

Determination of the viscosity of polymers in dilute solution using
capillary viscometers —
Part 2:
Poly(vinyl chloride) resins
1  Scope
This part of ISO 1628 specifies conditions for the determination of the reduced viscosity (also known as viscosity
number) and K-value of PVC resins. It is applicable to resins in powder form which consist of homopolymers of the
monomer vinyl chloride and copolymers, terpolymers, etc., of vinyl chloride with one or more other monomers, but
where vinyl chloride is the main constituent. The resins may contain small amounts of unpolymerized substances (e.g.
emulsifying or suspending agents, catalyst residues, etc.) and other substances added during the course of the
polymerization. This part of ISO 1628 is not applicable, however, to resins having a volatile-matter content in excess of
0,5 % – 0,1 %, when determined in accordance
