1.1 本标准的目的是规定使用本标准中定义的低危险测温液体的玻璃液体ASTM温度计。 1.2 本标准规定了玻璃液体温度计，其刻度为摄氏度或华氏度，在ASTM各技术委员会管辖下的方法中经常识别和使用。当前认可的温度计列于 表1 . 1.3 美国温度计用测温液体的技术要求 表1 在中指定 附件A1 . 符合技术要求的测试也可在 附件A1 . 注1: 经验表明，虽然ASTM温度计通常是为特定测试而开发的，但也可能适用于其他应用，因此不需要新的温度计规格，只在较小的特性上有所不同。 然而，建议技术委员会在为新方法选择当前指定的温度计之前联系E20.05，以确保温度计适用于预期应用。 1.4 有关完整原理，请参阅 附录X1 . 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、健康和环境实践，并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 The purpose of this standard is to specify liquid-in-glass ASTM thermometers using low hazard thermometric liquids defined in this standard. 1.2 This standard specifies liquid-in-glass thermometers graduated in degrees Celsius or degrees Fahrenheit that are frequently identified and used in methods under the jurisdiction of the various technical committees within ASTM. The current approved thermometers are listed in Table 1 . 1.3 The technical requirements for the thermometric liquids used in the thermometers in Table 1 are specified in Annex A1 . Tests for conformity to the technical requirements are also found in Annex A1 . Note 1: It has been found by experience that ASTM Thermometers, although developed in general for specific tests, may also be found suitable for other applications, thus precluding the need for new thermometer specifications differing in only minor features. However, it is suggested that technical committees contact E20.05 before choosing a currently designated thermometer for a new method to be sure the thermometer will be suitable for the intended application. 1.4 For full rationale, see Appendix X1 . 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
