This European Standard specifies six methods which, experience has shown, are suitable for measuring the viscosity of a wide range of adhesives:
- rotational viscometer method;
- cone and plate viscometer method;
- falling ball viscometer method;
- glass capillary viscometer method;
- flow cup method;
- pressurised extrusion method.
This standard does not intend to describe equipment, which is unique to one manufacturer, rather it describes generic types of viscometer. The instruments described operate on very different principles making it inadvisable to compare results from one type of viscometer with those from another. However, results from different instruments
of the same type should be comparable.
