14、al Barriers to Trade (TBT) Committee.1TABLE 1 REDUCTION OF OBSERVED RELATIVE DENSITY TO RELATIVE DENSITY 15.556/15.556 C (60/60 F)This table gives values of relative density 15.556/15.556 C (60/60 F) corresponding to specific gravities observed with a glass hydrometer at temperatures otherthan 60 F.
15、 The expression “Observed Relative Density” appears in this table because it is the term most generally used in industry. For specific gravities determinedby hydrometer, a more exact expression would be “hydrometer indication at the observed temperature.” This hydrometer indication differs slightly
16、from the truespecific gravity at the observed temperature owing to the expansion or contraction of the glass hydrometer when its temperature differs from its calibrationtemperature of 60 F.It is generally impracticable to determine a relative density at exactly 15.556 C (60 F) although it is at this
17、 temperature only that strictly correct results areobtained with a standard glass hydrometer. In converting an observed specific gravity at the observed temperature t F (hydrometer indication of relative densityt/60 F) to the corresponding 60/60 F value, two corrections are possible. The first arise
18、s from the change in volume of the glass hydrometer with temperature, andthe second arises from the change in volume of the butadiene. This table considers only the change in volume of the butadiene because the change in volumeofthehydrometer is insignificant in comparison with the accuracy of the v
19、alues for the change in volume of the butadiene.This table must be entered with specific gravities measured with a glass hydrometer calibrated at 15.556/15.556 C (60/60 F)ExampleIf the relative density observed on a hydrometer in butadiene at 40 F is 0.642, what is its relative density 60/60 F?Enter
20、 the table in the column for “Observed Relative Density,” headed 0.640, and note that against an “Observed Temperature” of 40 F, the correspondingrelative density 60/60 F is 0.627Likewise, note that for 0.645 specific gravity opposite 40 F, the corresponding relative density 60/60 F is 0.632This rep
21、resents an increase of 0.005 in relative density 60/60 F for an increase of 0.005 in the value at 40 F. Therefore, by simple proportion, anincrease in the specific gravity value noted at 40 F from 0.640 to 0.642 increases the corresponding relative density 60/60 F by 0.4 0.005 or 0.002Then, the rela
22、tive density 60/60 F corresponding to the observed relative density of 0.642 at 40 F is 0.627 + 0.002 or 0.629D1550 182TABLE 1 Reduction of Observed Relative Density to Relative Density 15.6/15.6C (60/60F)18.343.0 C (65110 F) 0.5850.615ObservedTemperatureFAObserved Relative Density0.585 0.590 0.595
