Friction material thermal decomposition temperature measurement method
1 Scope
This standard specifies the determination of the thermal decomposition temperature of friction material terms and definitions, test equipment, sample preparation, equipment calibration, test procedure,
Expression of results and test report.
This standard applies to the determination of the decomposition temperature and decomposition rate of the dry friction material, is also applicable to the determination of friction materials contained volatiles, Tim
The content of additives and/or fillers, the friction material can refer to the use of raw materials.
This standard applies to the dynamic mode (under the conditions of the program quality over time or temperature change) or isothermal mode (at a constant temperature with the quality
Thermal weight measurement time) under.
2 Terms and definitions
The following terms and definitions apply to this document.
2.1
Thermal gravimetric analysis thermogravimetry
TG
Under the program temperature control, measuring the quality of the relationship between a technology sample temperature or time.
2.2
Dynamic mass change measurement dynamicmass-changedetermination
Under the program ramp rate, recording a technology sample mass with temperature change.
2.3
Isothermal mass change measurement isothermalmass-changedetermination
Under constant conditions, the quality of the sample recorded a technology change over time.
2.4
TG curve TGcurve
Obtained by a thermal gravimetric analysis curve, the quality of the sample to the ordinate (y-axis) at a temperature of T or time t as the abscissa (x-axis).
2.5
Differential scanning calorimetry differentialscanningcalorimetry
DSC
Under the program temperature and a certain atmosphere, measuring the sample and reference was lost to the rate of heat flow and heating power (difference) and the temperature and/or time
Technical relations.
