1、Designation:D1555M22Standard Test Method forCalculation of Volume and Weight of Industrial AromaticHydrocarbons and Cyclohexane Metric1This standard is issued under the fixed designation D1555M;the number immediately following the designation indicates the year oforiginal adoption or,in the case of
2、revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This standard is for use in calculating the weight andvolume of benzene,toluene,mixed xylenes,styrene
3、,ortho-xylene,meta-xylene,para-xylene,cumene,ethylbenzene,148.9to176.7 Cand176.7to204.4 Caromatichydrocarbons,and cyclohexane.A method is given for calcu-lating the volume at a given temperature from an observedvolume at an observed temperature,t C.Table 1 lists thedensity in Vacuo at 15 F and 20 C
4、for chemicals used todevelop the relationship.Densities(or weights)“in vacuo”represent the true density(or weight)if measured in a vacuumwithout the buoyancy effect of air acting on the liquid.It isrepresentative of the actual amount of product present.Densi-ties(or weights)“in air”represent what wo
5、uld be measured ona scale.The difference is on the order of 0.13%.Moderndensitometers measure density in vacuo and the ASTM recom-mends the use of in vacuo densities(or weights).1.2 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard
