2 Normative references

The following documents for the application of this document is essential. For dated references, only the dated version suitable for use herein Member. For undated references, the latest edition (including any amendments) applies to this document. GB/T 13609 Gas sampling guidelines Principle 3 Under constant pressure test, gas flow through the sample at a constant dew point measuring chamber polished metal mirror, the mirror temperature Keren To reduce and can accurately measure. When the gas is gradually reduced as the temperature of the mirror, and just began to precipitate hydrocarbon condensate, then the measured mirror Hydrocarbon dew point is the temperature of the gas at this pressure. Note. The difference between the hydrocarbon dew point and water dew formation of shapes and colors on the mirror in Appendix A.
