GB/T 27848-2011 《Liquid asphalt and derivatives - Determination of flash point - Abel closed tester》 Related products

GB/T 27848-2011 For liquid asphalt and dilute asphalt, it is stipulated to use the Abel closed cup method to measure the flash point. The principle is to heat up the sample in the closed cup and detect the flash point by timing ignition. The standard specifies the specifications of the Abel closed cup tester, such as the cup structure and ignition device requirements. Detail the sample preparation, covering the collection and temperature pretreatment of liquid asphalt and dilute asphalt. Standardize the heating rate, ignition interval and other operations, so that the detection can be carried out in an orderly manner. According to this standard, the flash point of such asphalt can be accurately determined, providing key data support for fire safety in its production, storage and transportation.
