Scope1.1 This specification c
3、overs liquid-in-glass thermometers graduated in degrees Celsius or degrees Fahrenheit that arefrequently identified and used in methods under the jurisdiction of the various technical committees within ASTM. The variousthermometers specified are listed in Table 1. Table 1. The inclusion of an IP num
4、ber in Table 1Table 1 indicates, where appearing,that the thermometer specification has been jointly agreed upon by the British Institute of Petroleum (IP) and ASTM.1.2 This specification also covers adjustable-range enclosed-scale thermometers, graduated in degrees Celsius, which are usedin ASTM me
5、thods.1.3 The enclosed-scale thermometers are commonly called Beckmann thermometers. They are suitable for measuring smalltemperature differences not exceeding 6 C within a larger range of temperature. The thermometers are unsuitable for measuringCelsius- or kelvin-scale temperatures unless they hav
6、e been compared with standard instruments immediately before use.1.4 An alphabetic list of the ASTM Thermometers included in this standard is given in Table 2.Table 2.1.5 A list of ASTM Thermometers is given in Table 3Table 3 to facilitate selection according to temperature range, immersion,and scal
7、e-error requirements.NOTE 1For a listing of thermometers recommended for general laboratory use, the ScientificApparatus MakersAssociation Specifications for GeneralPurpose Glass Laboratory Thermometers may be consulted.2NOTE 2It has been found by experience that theseASTM Thermometers, although dev
8、eloped in general for specific tests, may also be found suitablefor other applications, thus precluding the need for new thermometer specifications differing in only minor features. However, it is suggested that technicalcommittees contact Subcommittee E20.05 before choosing a currently specified th
9、ermometer for a new method to be sure the thermometer will be suitablefor the intended application.1.6 The thermometers found in Table 1Table 1 contain mercury, mercury thallium eutectic alloy, or toluene or other suitableliquid colored with a permanent red dye. For low-hazard precision non-mercury
10、alternatives to E1 thermometers, see SpecificationE2251.1.7 WARNINGMercury has been designated by EPA and many state agencies as a hazardous material that can cause centralnervous system, kidney and liver damage. Mercury, or its vapor, may be hazardous to health and corrosive to materials. Cautionsh

See the applicable product Material Safety Data Sheet(MSDS) for details and EPAs website- http:/www.epa.gov/mercury/faq.htm - for additional information.
