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 Light Hydrocarbon Liquids, the subroutines follow appendix A of ASTM-IP-API Petroleum Measurement Tables for Light Hydrocarbon Liquids, The Institute of Petroleum, London, 1986.

Data limits
The data limits (including extrapolated range) are identical to the limits of the paper tables.

Erratum

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.

Developers Edition
A developer kit is available at 499GBP + 19GBP per redistribution licence (per block of 10 and depending on the volume).
