The subroutines are prepared according to the ASTM D 1250-80 Volume X implementation procedures and were tested according to the examples for checkout as outlined in the same volume. They also comply with volume XIII and volume XIV appendix A and B.
For the Light Hydrocarbons Liquids, the subroutines follow the appendix A of ASTM-IP-API Petroleum Measurement Tables for Light Hydrocarbon Liquids, The Institute of Petroleum, London, 1986.
The data limits (including extrapolated range) are identical to the limits of the paper tables.
Table 53L (Light Hydrocarbons)
There is a typo for the reference value for 50°C and density 0.470 Kg/litre in the table 53L: the density @15°C has been entered as 0.532 Kg/litre instead of 0.523 Kg/litre.
The interpolation for the densities between 0.460 and 0.480 is incorrect as a consequence of this typo.
A developer kit is available at 499GBP + 19GBP per redistribution licence (per block of 10 and depending on the volume).
The kit includes a library with the full ASTM Petroleum Measurement Tables (Win32 DLL library and .Net DLL Class library).
The source code (C++) is also available at 5000GBP (for use within an organisation, not for resale to third-parties).
