18、cifications4.1 Individual hydrometers shall conform to the detailed specifications in TableTable 1 1 and to the general requirementsspecified in Sections 5 15.4.2 Hydrometers shall be subjected to the initial calibration criteria found in Section 14, the inspection criteria found in Section16, and t

19、he standardization calibration and verification criteria found in Section 17.4.3 Hydrometers manufactured to previous revisions of this specification shall retain the same ASTM status as those meetingcurrent specifications.4.4 At the time of purchase, scale errors shall be within the maximum scale e

20、rror found in Table 1Table 1NOTE 1CautionUsers should be aware that both temperature and density indications of thermohydrometers may change with rough handling,shock, exposure to aggressive liquids, and thermal cycling, among other factors. Consequently, test results and performance obtained at the

21、 time ofmanufacture may not necessarily apply throughout an extended period of use. Periodic calibration or verification of these instruments, in accordance withprocedures set forth in Test Method E126 (for the hydrometer), or Test Method E77 (for the integral thermometer), is recommended5. Type5.1

22、Hydrometers shall be of the constant-mass, variable-displacement type. Hydrometers shall be made of glass, except for thescale, ballast, and the thermometric liquid of thermohydrometers.5.2 The outer surface of the stem and body shall be symmetrical about the vertical axis. There shall be no uneven

23、or unnecessarythickening of the walls, and no abrupt changes or constrictions that would hinder thorough cleaning or tend to trap air bubbles whenthe instrument is immersed.5.3 The hydrometer shall always float with its axis vertical in liquids for which it is intended.5.4 The hydrometer shall be th

24、oroughly dry on the inside when sealed. The top of the stem shall be neatly rounded withoutunnecessary thickening.5.5 The glass shall be smooth, transparent, and free of bubbles, cracks, strain patterns, or other imperfections that might interferewith the use of the hydrometer. The glass shall adequ

25、ately resist the reaction of chemical agents to which hydrometers may beexposed and shall have suitable thermal properties to permit its use over the range of temperatures to which it may be subjected.In general, glasses suitable for constructing the bulbs of thermometers are satisfactory for hydrom

26、eters.5.6 These hydrometers and thermohydrometers shall be fabricated from soda-lime glass tubing having a thermal cubicalexpansion coefficient of (25 +/- 2) x 10-6 per C.NOTE 2The value of the thermal cubical expansion coefficient given above is consistent with the conventional value given in ISO 1
