1 Subject content and applicable scope

This standard specifies the test apparatus, sample preparation and test procedures for the determination of the softening point of hot-melt adhesives by ball and ring method.

This standard is applicable to the determination of softening point of solid hot-melt adhesives.

2 Principle

The steel ball with a certain mass is placed on the metal ring filled with the sample. Under the specified temperature rise condition, the steel ball enters the sample and falls from a certain height. When the steel ball contacts the bottom metal baffle, the temperature at this time is regarded as the softening point.
