Scope
This part of GB/T 26930 specifies the Mettler method for the determination of the softening point of coal tar pitch, the measurement range: 50 ℃ ~ 180 ℃. This section applies to the determination of coal tar pitch with a Mettler softening point of 50 °C to 180 °C. It is also suitable for the determination of other organic materials used as adhesives or sizing agents with a Mettler softening point of 50 ℃ ~ 150 ℃.
