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

11、on procedures presented in Method D 1555 - 04a.4.3 The former VCF tables were based on data for com-pounds of the highest purity, but were reported to be usable formaterials in the ranges indicated in Table 2. 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
