Ring and Ball Apparatus
EN 1427 | ASTM D36 | AASHTO T53
The Automatic Ring and Ball Tester allows fully automatic performance of softening point determination of binders conforming to most common international Standards.
Two binder specimens, cast in shouldered brass rings, are heated at a controlled temperature rate in a water or glycerol bath while each supports a steel ball. The softening point corresponds to the average temperature at which the two specimens soften enough to allow each ball, enveloped in binder, to fall 25mm, automatically detected by a calibrated light barrier.
