GB/T 15332-1994 "Determination of Softening Point of Hot-Melt Adhesives—Ring-and-Ball Method" applies to the determination of the softening point of hot-melt adhesives using the ring-and-ball method. It specifies the required instruments and equipment, sample preparation, test conditions, and operational procedures. The softening point is determined by measuring the temperature at which the hot-melt adhesive softens and drips under heating in a standardized ring-and-ball apparatus. This standard provides a key technical indicator basis for evaluating the performance, quality control, and application suitability of hot-melt adhesives, and is applicable to production inspection and selection for various types of hot-melt adhesives.
