Foreword

The standard reference ASTMD2639.2004 "Determination of coal plasticity constant torque Gibbs plastic instrument Laws". This standard ASTM D2639 main differences are as follows. --- Modified ASTMD2639 of "plastic range" is defined; --- The ASTMD2639 provisions "about 4kg of particle size less than 4.75mm coal laboratory coal" to "size of less than 4kg 6mm laboratory coal "; --- Increasing the torque meter and sensor measurements in plastic instrument calibration torque. The standard proposed by China Coal Industry Association. This standard coal by the National Standardization Technical Committee (SAC/TC42) centralized. This standard was drafted. CCRI coal analysis laboratory. The main drafters of this standard. Wang Lihua, Ling slope. This standard was first formulated. Coal - Determination of plasticity constant torque Gibbs plastic instrument law

1 Scope
