JJF 1464-2014 "Specification for calibrating interfacial tension meters" applies to the calibrating of interfacial tension meters for measurement by platinum ring method or platinum plate method. This specification refers to several relevant standards, such as GB/T 5549-2010, GB/T 6541-1986, GB/T 8170-2008, etc. The interfacial tension meter is used for the measurement of tension at the liquid-liquid or liquid-gas interface through the measurement of surface tension at the liquid interface. The instrument structure includes tension measurement device, test bench, controllable mobile device and platinum ring, stirrup ring or platinum plate. According to the structure and principle, the interfacial tension instrument is divided into mechanical and electronic types, which can be measured by platinum ring method or platinum plate method.
