ASTM D1550-94(2009)

Standard ASTM Butadiene Measurement Tables

SCOPE
1.1 The ASTM Butadiene Measurement Tables are for use in the calculation of quantities of butadiene. The accompanying Tables 1-4 cover the normal operating ranges for the reduction of observed specific gravity and volume to 15.6/15.6°C/(60/60°F) and for the calculation of weight-volume relationships of butadiene.
1.2 These tables are applicable to both butadiene and butadiene concentrates (minimum of 60% butadiene).
Note 1--These tables replace the existing tables in the National Institute of Standards and Technology Letter Circulars LC-736 and LC-757 and the Rubber Reserve Corp., Butadiene Laboratory Manual.
1.3 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 and health practices and determine the applicability of regulatory limitations prior to use.

TABLE 1 REDUCTION OF OBSERVED SPECIFIC GRAVITY TO SPECIFIC GRAVITY 15.6/15.6°C (60/60°F)
This table gives values of specific gravity 15.6/15.6°C (60/60°F) corresponding to specific gravities observed with a glass hydrometer at temperatures other than
60°F. The expression “Observed Specific Gravity” appears in this table because it is the term most generally used in industry. For specific gravities determined by
hydrometer, a more exact expression would be “hydrometer indication at the observed temperature.” This hydrometer indication differs slightly from the true specific
gravity at the observed temperature owing to the expansion or contraction of the glass hydrometer when its temperature differs from its calibration temperature of
60°F.
It is generally impracticable to determine a specific gravity at exactly 15.6°C (60°F) although it is at this temperature only that strictly correct results are obtained
with a standard glass hydrometer. In converting an observed specific gravity at the observed temperature t F (hydrometer indication of specific gravity t/60°F) to the
corresponding 60/60°F value, two corrections are possible. The first arises from the change in volume of the glass hydrometer with temperature, and the second
arises from the change in volume of the butadiene. This table takes into account only the change in volume of the butadiene because the change in volume ofthe
hydrometer is insignificant in comparison with the accuracy of the values for the change in volume of the butadiene.
This table must be entered with specific gravities measured with a glass hydrometer calibrated at 15.6/15.6°C (60/60°F)
Example—If the specific gravity observed on a hydrometer in butadiene at 40°F is 0.642, what is its specific gravity 60/60°F?
Enter the table in the column for “Observed Specific Gravity,” headed 0.640, and note that against an “Observed Temperature” of 40°F, the corresponding
specific gravity 60/60°F is 0.627
Likewise, note that for 0.645 specific gravity opposite 40°F, the corresponding specific gravity 60/60°F is 0.632
This represents an increase of 0.005 in specific gravity 60/60°F for an increase of 0.005 in the value at 40°F. Therefore, by simple proportion, an increase
in the specific gravity value noted at 40°F from 0.640 to 0.642 increases the corresponding specific gravity 60/60°F by 0.4 × 0.005 or 0.002
Then, the specific gravity 60/60°F corresponding to the observed specific gravity of 0.642 at 40°F is 0.627 + 0.002 or 0.629
