Summary This Standard specifies the non-metallic sealing material thermal decomposition temperature measurement terminology and definitions, the principles outlined, test equipment, sample preparation, equipment calibration, test procedures, test results and report presentation. This Standard applies to the determination of the decomposition temperature and decomposition rate of non-metallic sealing material is also suitable for the determination of non-metallic sealing materials contained volatiles, additives and/or filler content, non-metallic sealing material may also refer to the use of raw materials. Thermal weight measurement This Standard applies to the dynamic mode (quality change with temperature or time under program conditions) or isothermal mode (quality changes with time at a constant temperature).

1 Scope

This standard specifies the non-metallic sealing material thermal decomposition temperature measurement terminology and definitions, the principles outlined, test equipment, sample preparation, equipment Calibration, test procedures, test report and results presentation. This standard applies to the determination of the decomposition temperature and decomposition rate of non-metallic sealing material is also suitable for the determination of non-metallic sealing materials contained Volatile matter content, additives and/or filler material, non-metallic sealing materials may also 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, a method of sample quality relationship with temperature or time measurements. 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. 2.6 Differential thermal analysis differentialthermalanalysis; DTA In the program temperature control, the temperature difference between the measuring technique the relationship between temperature and/or time of sample and reference material between. 2.7 Curie temperature curietemperature Magnetic material can be between the ferromagnetic transition temperature of the magnet rolls. 2.8 Thermal decomposition temperature thermaldecompositiontemperature Thermal decomposition of material failure when the corresponding temperature.
