ISO 9944-1990 – Determination of the electrical conductivity of resin extracts from plastic phenolic resins

introduction
ISO (International Organization for Standardization) is a global alliance of national standards bodies (ISO member bodies). The development of international standards is usually carried out through ISO technical committees. Each member institution interested in a subject on which a technical committee has been established has the right to be represented on that committee. International governmental and non-governmental organizations liaising with ISO are also involved in this work. ISO works closely with the International Electrotechnical Commission (IEC) on all matters of electrical standardization.

The draft international standard adopted by the Technical Committee will be circulated to the member bodies for voting. Publication as an international standard requires approval by at least 75% of member institutions.

The international standard ISO 9944 was developed by the Technical Committee ISO/TC 61, Plastics.

ISO 9944-1990 – Determination of the electrical conductivity of resin extracts from plastic phenolic resins

1 Range
This standard specifies a method for determining the electrical conductivity of phenolic resin extracts at 23°C±2°C.

This method is important for applications where such resins are used as impregnating materials.
