EN ISO 182-3:2000

Plastics - Determination of the tendency of compounds and products based on vinyl chloride homopolymers and copolymers to evolve hydrogen chloride and any other acidic products at elevated temperatures - Part 3: Conductometric method (ISO 182-3:1993)

The principle of the method is maintaining a test portion of the PVC at an agreed temperature in a nitrogen gas stream, absorbing the hydrogen chloride evolved in a given amount of demineralized water, and potentiometrically determining the amount of hydrogen chloride evolved in relation to the recorded change in conductivity of the water. The method is recommended for compounded PVC materials and products only, although it can be used for polymers in powder form under appropriate conditions.

Kunststoffe - Bestimmung der Neigung von Formmassen und Erzeugnissen auf der Basis von Vinyl-chlorid-Homopolymeren und -Copolymeren, bei erhöhten Temperaturen Chlorwasserstoff und andere saure Produkte abzugeben - Teil 3: Leitfähigkeitsverfahren (ISO 182-3:1993)

Dieser Teil von ISO 182 legt ein Verfahren zur Bestimmung der thermischen Stabilität bei erhöhter Temperatur von Formmassen und Erzeugnissen fest, die auf der Grundlage von Vinylchlorid-Homopolymeren und -Copolymeren (im folgenden Text abgekürzt als PVC) hergestellt sind und die zum Chlorwasserstoffverlust neigen (Entwicklung von Chlorwasserstoff). Das Verfahren kann zur Qualitätskontrolle während der Herstellung und Umwandlung von PVC-Formmassen angewendet werden.

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
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 IS0 182-3 was prepared by Technical Committee
lSO/TC 61, Plastics, Sub-Committee SC 6, Ageing, chemical and environ-
mental resistance.
Together with the three other parts of IS0 182, it cancels and replaces IS0
Recommendation R 182:1970, of which the four parts of IS0 182 consti-
tute a technical revision.
IS0 182 consists of the following parts, under the general title
Plastics - Determination of the tendency of compounds and products
based on vinyl chloride homopolymers and copolymers to evolve hydrogen
chloride and any other acidic products at elevated temperatures:
- Part 1: Congo red method
- Part 2: pH method
- Part 3: Conductometric method
- Part 4: Po tentiometric method
Annexes A, B and C of this part of IS0 182 are for information only.
