1.1本试验方法包括通过水蒸气在冷却表面上的冷凝来测定环境空气的热力学露点或冰点温度。为简便起见，本方法中称之为冷凝温度。 1.2本试验方法适用于60℃至70℃的冷凝温度范围。 1.3本试验方法包括仪器和操作程序的一般说明，包括用于获得测量值的场地选择，以及用于计算结果的程序的说明。 1.4本试验方法适用于在固定平台上连续测量自然大气中的环境湿度。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 有关具体的预防说明，请参阅第8节。

1.1 This test method covers the determination of the thermodynamic dew- or frost-point temperature of ambient air by the condensation of water vapor on a cooled surface. For brevity this is referred to in this method as the condensation temperature. 1.2 This test method is applicable for the range of condensation temperatures from 60C to 70C. 1.3 This test method includes a general description of the instrumentation and operational procedures, including site selection, to be used for obtaining the measurements and a description of the procedures to be used for calculating the results. 1.4 This test method is applicable for the continuous measurement of ambient humidity in the natural atmosphere on a stationary platform. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements, see Section 8.
