1、Designation: E1 13 Method 9501Federal TestMethod Standard No. 791bStandard Specification forASTM Liquid-in-Glass Thermometers1This standard is issued under the fixed designation E1; the number immediately following the designation indicates the year of originaladoption or, in the case of revision, t
2、he year of last revision. A number in parentheses indicates the year of last reapproval. A superscriptepsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This specification covers

5、e thermometers are commonly calledBeckmann thermometers. They are suitable for measuringsmall temperature differences not exceeding 6 C within alarger range of temperature. The thermometers are unsuitablefor measuring Celsius- or kelvin-scale temperatures unless theyhave been compared with standard
