Analysis Method GB/T 212 coal GB 474 coal sample preparation GB/T 483 coal analysis test methods - General provisions GB/T 1598 platinum and rhodium 10 - platinum thermocouple wire, platinum and rhodium 13 - platinum thermocouple wire, platinum and rhodium 30 - 6 platinum and rhodium thermocouple wires3 Terms and DefinitionsGB/T 483 as defined in the following terms and definitions apply to this document. 3.1 Ash viscosity ashviscosity Ash in the molten state a measure of the flow resistance. [GB/T 483-2007, the definition 3.3.33] 3.2 Dynamic viscosity dynamicviscosity Each area of \u200b\u200b1m2 and two fluid 1m apart, the internal friction at a speed 1m/s of the relative movement generated. 3.3 Critical Viscosity criticalviscosity Ash viscosity - temperature curve in the intersection of two tangents temperature corresponding to the critical temperature viscosity, viscosity at this temperature is the critical viscosity.4 Method summaryThe ash made appropriately sized pellets, one by one into a high temperature furnace has been heated to a temperature of crucible melting, the wire torque formula The viscometer spindle is inserted and allowed to melt at a constant speed. Use cool determination, beginning from the highest temperature every 20 ℃ ~ A temperature measuring point 50 ℃ wire twist angle until the viscosity is greater than 50 (or 100) Pa · s. Isolated on the twist angle of each temperature curve - from viscosity Viscosity of the point at a temperature as abscissa and ordinate viscosity draw temperature - viscosity curve.5 Reagents and materials5.1 Viscosity Standards 5.1.1 Silicone oil. viscosity values \u200b\u200bare known (about 1Pa · s, 5Pa · s, 10Pa · s, 25Pa · s, 50Pa · s and 100Pa · s) of standard certified ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 31424-2015_English be delivered?Answer: Upon your order, we will start to translate GB/T 31424-2015_English as soon as possible, and keep you informed of the progress.
