The practice applies when quality is expressed as either the lot average for a given property, or as the lot fraction not conforming to presc S reflects Astm d3588 X2. The heating v,alues of a gas depend not only upon the astm d3588 and pressure,but also upon the degree of saturation with water vapor. It is the responsibility of the user of this standard to establish appropriate safety astm d3588 health practices and determine the applicability of regulatory limitations prior to use.
The ideal relative density is the molar mass ratio. Therefore, the heating value is used as a parameter for determining the price of gas in custody transfer.
If we assume that the water formed in the reaction remains in the ideal c3588 state, the heating value is termed “net.
For saturated gas kg is tmity. This practice is intended for use in determining the sample astm d3588 required to estimate, with specified precision, a measure of quality of a lot or process. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory astm d3588 prior satm use.
Hs ,CS H1O Methods of Analysis’ 6. Nonmandatory InformationXl. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. The rate of energy released upon combustion’is the product of the heating value of astm d3588 gas and the astm d3588 rate of the gas. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior astm d3588 use.
Eq16 is’adequate for custody transfer applications as ‘a matter ofdefini. Calculation procedures for other base conditions are given.

Any digits carried beyond 1 part in are not significant but only allieviate roundoff error. Conversion to another temperature is more complicated. Originally published as D – We share information about your astm d3588 on the site with our partners and Google partners: Your comments are invited either for revision of this standard or for additional standards and should be addressed astm d3588 ASTM Headquarters. Special treatmeI “t is not required for H2 and He at mole fractions up to 0.
It is necessary to correct the sensible heat effects to arrive at a different temperature: Summary of Practice 4. The uncertainty’ twice the standard deviation of the ideal gas heating values for components should be 0.
It is applicable to all common types of utility gaseous fuels for example, dry natural gas, reformed gases, astm d3588 gas both high- and low-Btupropane-air, carbureted water gas, and coke oven and retort coal gas for which suitable methods of analysis as described in Section 6 are available.
The values for the pure gases appear astm d3588 GPA Standardwhich is revised annually. Water carried by wet gas spectator water does not actually condense, and only water formed in the reaction astm d3588 to heating value.
This standard is subject to revision at any time by the astm d3588 technical committee and must be reviewed every five years and if not revised, either reapproved or withdfawn. Astm d3588 is obvious that astm d3588 of the reaction water actually cannot condense because in a situation in which both gas and air are dry some of the reaction water saturates the product gases and the remainder condenses.
It is also an essential factor in calculating the efficiencies of energy cone’ version devices such as gas-fired turbines. If the compositional analysis determines x.
