DIN 1871:1999-05

The document contains numerical values of the density, the compressibility factor and other volumetric quantities, at standard reference conditions, and numerical values of the second virial coefficients at 0 °C and 30 °C for a selection of gases of technical relevance, in particular gases that occur as constituents of gaseous fuels. In addition calculation procedures for the conversion of volumetric quantities of gases and gas mixtures between different conditions of state (pressures up to 2 bar, temperatures from 0 °C to 30 °C) are standardized.
