Melting point standards regularly calibrate analogue or digital apparatuses to guarantee reliable identity and purity determinations. Thermometer, capillary tube, or heater parameters often experience equipment failure that would cause phase changing results to fall outside acceptable limits. If the melting point differs from the reference substance predetermined range, the error indicates that equipment adjustments are necessary. Used in pharmaceuticals, the ground melting point standards promote consistent drug manufacturing for consumer satisfaction and department regulations.
