Basic Data4.1 Densities of pure materials at 15C and 20C are derivedfrom densities furnished by NSRDS-NIST 7
10、5-121 (NationalStandard Reference Data SeriesNational Institute of Stan-dards and Technology). Densities of impure materials shouldbe determined by actual measurement (see Section 7).4.2 The VCF (Volume Correction Factor) equations pro-vided below are derived from the Volume Correction imple-mentati

The data support-ing this conclusion appears to be unavailable at the presenttime; however
12、 there is no reason to change this recommenda-tion. If, depending on the composition of the impurities, thereis reason to suspect that the VCF implementation procedurespresented below do not apply to a particular impure product, aseparate implementation procedure should be independentlydetermined. T
