Ehdotuksen tiedot

The purpose of this international standard is to provide a test method in terms of calibration error for radiosonde temperature sensors sampled from a batch of mass production, with varying temperature in laboratory setups at ground level pressure. This International Standard will elaborate on the following information: Specifically, the requirements for test chamber and reference thermometers as essential laboratory setups are proposed in part (a). In part (b), the test procedure includes the installation of radiosondes in the test chamber, the operation of laboratory setups, and the comparison between radiosonde and the temperature references. In part (c), the method for evaluating uncertainties related to the references and the radiosonde sensors is proposed.
