I. Summary
    This instrument is designed and made as per Chinese GB/T ***7 Standard Test Method for Softening Point of Bitumenand Chinese industrial standard T********1 Test Method for Softening Point of Bitumen(ring and ball method) in JTG E******1 Standard Teste Methods of Bitumen and Bituminous Mixtures for Highway Engineering. It is suitable to test make determination for softening point of petroleum asphalt for road, coal pitch and liquid petroleum asphalt. It can also make determination for softening point of resin, oil fats and other relevant materials. It is the best choice for bitumen manufacturer, colleges, research institute and relevant industries.
