ASTM D1550-94(2009)

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.
