"ASTM D56-2005 (2010) Standard Test Method for Determination of Flash Point by Tiger Closed Flash Point Tester" is an international standard for the determination of flash point of liquid samples. This method is suitable for testing volatile liquids with flash point in the range of 0 ° C to 110 ° C. It uses Tiger Closed Flash Point Tester and has high safety and measurement accuracy. The standard content includes equipment requirements, test procedures, sample preparation, test conditions, and data recording and reporting formats. This method can effectively evaluate the flammability characteristics of liquid samples and provide key safety parameters for the storage, transportation and use of chemical products. This standard is widely used in the chemical, petroleum, and related industries to help meet product safety and regulatory requirements.
