Glass Alcoholometers - Part 2 : Glass Alcoholometers With Thermometer (thermo-alcoholometers)

This technical specification establishes the requirements and test methods for a specific type of alcoholmeter equipped with an integrated thermometer, designed for the measurement of ethanol content in liquids at elevated temperatures. The document outlines the necessary design characteristics, including the material composition of the glass body and the accuracy specifications for the attached temperature measuring device. It defines the calibration procedures to ensure consistent readings across different thermal conditions and provides guidelines for the construction and marking of the instrument to prevent ambiguity during field use. The scope covers the dimensional tolerances, scale graduation intervals, and the method for verifying the integrity of the assembly under operational stress. Furthermore, it addresses the environmental conditions under which the measurements are valid and the steps required to maintain the device's reliability over time. By adhering to these provisions, manufacturers and users can ensure that the measurement instruments meet rigorous quality standards, facilitating accurate determination of alcohol content in industrial and commercial applications without the need for external thermometers.
