All Implemented Interfaces:

WaterVaporPressureProvider

public class NbsNrcSteamTable
extends Object
implements WaterVaporPressureProvider

Steam table from US National Bureau of Standards (NBS) and National Research Council (NRC) of Canada.

The table is an extract from table 1 in Thermopedia, using only the pressure column and truncated to 99°C (the original table goes up to 373.976°C). According to the access page, this data is available for free.
