1.1 These test methods are intended for determining the softening point of hydrocarbon resins, rosin based resins and similar materials by means of an automated ring-and-ball apparatus. Portions are similar in technical content to the automated-apparatus versions of Test Methods D36, E28, and ISO 4625.
1.1.1 The ring-and-ball softening point of a hydrocarbon resin and rosin based resins may also be determined with lower precision using the manual ring-and-ball softening point procedure in Test Methods E28.
