Abstract

Thirteen reference standards (TherMetric melting point standards and NBS-ICTA standards) for temperature calibration of DTA in the range from 50 to 425° have been compared and found to be accurate to within ±0.5°. Most of these standards are shown to be usable to at least 100°/min heating rates.

Résumé

On a comparé treize substances étalons pour l'échelle des températures en ATD entre 50 et 425° (étalons de points de fusion TherMetric et étalons NBS-ICTA) et l'on a trouvé que leur exactitude était de ±0.5°. On montre que la plupart de ces étalons peut être utilisée jusqu'aux vitesses de chauffage de 100°C/min.

Zusammenfassung

Dreizehn Referenzstandarde (TherMetric Schmelzpunktstandarde und NBS-ICTA Standarde) zur Temperatur-Eichung von DTA zwischen 50 und 425° wurden verglichen und innerhalb von ± 0.5° für genau gefunden. Es erwies sich, daß die meisten dieser Standarde bis Aufheizungsgeschwindigkeiten von 100°C/min verwendbar sind.

Резюме

Проведено сравнение 13 стандартных материа лов (TherMetric melting point standards and NBS—ICTA standards) для калибровки температуры ДТА в обл асти 50–425° и обнаружено, что р азброс точек не превы шает ± 0,5°. Показано, что большин ство из этих стандартов мо жно использовать при скоростях нагрева до 100°/мин.
