Foreword
This standard is the international standard ISO 13443.1996 "Gas --- Standard reference conditions" non-equivalent.
This standard and ISO 13443.1996 is a major difference.
--- The ISO 13443 standard using only the prescribed standard reference pressure, there is no standard in the standard reference temperature of
A predetermined reference temperature is 20 ℃ (293.15K).
--- The Standard Appendix A increases the volume of heat and other physical property values \u200b\u200bconverted from the 20.20 to 15.15 and converted to 0.0,20.20
25.0 converted to 18 at 20.20 conversion factor reference conditions corresponding property value.
--- The standard Appendices B and D is given 101.325kPa, 20 ℃ conversion equations and calculations and other reference conditions shown
Example, while ISO 13443 Appendix B and Appendix D is given 101.325kPa, 15 ℃ conversion equations and other reference conditions
Calculation examples.
This standard replaces GB/T 19205-2003 "gas standard reference conditions."
This standard and GB/T 19205-2003 compared to the main changes are as follows.
--- This standard and ISO 13443.1996 is consistent, increased humidity (saturation) standard reference conditions. For real dried
Gas alone shows the standard reference conditions of use.
--- This standard canceled the GB/T 19205-2003 references, this reference is GB/T 17291-1998 "liquid petroleum gas
Standard reference conditions "body measurement, the corresponding also canceled GB/T 19205-2003 and related Notes 1.
The Standard Annexes A and C are normative appendix, Appendix B, Appendix D and Appendix E is an informative annex.
Note 1. ISO 13443 standard reference conditions specified is 101.325kPa, 15 ℃ (288.15K).
Note 2. GB/T 11062-1998, the drying gas is defined as gas, water vapor mole fraction is less than 0.00005, but in this standard applications
Need not be so strict, allows water vapor to the mole fraction of not more than 0.001.
Note 3. When there is confusion may occur, it can be related to the reference conditions as part of the sign, together with the representatives of the physical quantity, rather than the single
Bits together. E.g.
Represented by Z (101.325kPa, 0 ℃) under "101.325kPa, 0 ℃" reference conditions of compression factor instead of Zn represented;
With Vp (101.325kPa, 293.15K)/m3 expressed in "101.325kPa, 293.15K" reference conditions m3 gas metered volume without
With mn3, m3 (n), nm3 or Nm3 expressed, it can not simply be expressed in m3.
When confusion does not occur, similar to the Z (0) and Vp (20)/m3 of such abbreviations also acceptable. For Vp (101.325kPa,
15 ℃)/m3 this case, the Vp (ISO )/m3 said it may be the best representation.
