1.1本指南描述了冰点传感器和辅助设备的基本特征，以及在29至1085°C温度范围内实现冰点所需的技术。 1.2本指南不涉及详细设计和施工。 1.3本指南旨在描述良好实践，并建立实现冰点的统一程序。 1.4本指南强调原则。对原则的强调旨在帮助用户评估单元、改进单元使用技术以及建立特定应用程序的程序。 1.5在本指南中，用于准确校准温度计的冰点电池仅限于浸入式温度计，当插入电池的凹口时，（1）仅指示孔的等温区域的温度，（2）不会通过热传递显著改变孔的等温区域的温度。 1.6本指南并未涉及温度计校准的所有细节。 1.7本指南旨在补充冰点仪制造商提供的特殊操作说明。 1.8以下危险警告仅适用于本指南第7节试验方法部分。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。

1.1 This guide describes the essential features of freezing-point cells and auxiliary apparatus, and the techniques required to realize freezing points in the temperature range from 29 to 1085°C. 1.2 Detailed design and construction are not addressed in this guide. 1.3 This guide is intended to describe good practice and establish uniform procedures for the realization of freezing points. 1.4 This guide emphasizes principles. The emphasis on principles is intended to aid the user in evaluating cells, in improving technique for using cells, and in establishing procedures for specific applications. 1.5 For the purposes of this guide, the use of freezing-point cells for the accurate calibration of thermometers is restricted to immersion-type thermometers that, when inserted into the reentrant well of the cell, (1) indicate the temperature only of the isothermal region of the well, and (2) do not significantly alter the temperature of the isothermal region of the well by heat transfer. 1.6 This guide does not address all of the details of thermometer calibration. 1.7 This guide is intended to complement special operating instructions supplied by manufacturers of freezing-point apparatus. 1.8 The following hazard caveat pertains only to the test method portion, Section 7, of this guide. This standard does not purport to address all of the safety problems, 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.
