Natural gas - Determination of particulate matter content Gravimetric method
1 Scope
This standard specifies the method for the determination of particulate matter content of natural gas by the filter weighing method.
This standard applies to the determination of the content of particulate matter in the gas, measured pressure of 0.1MPa ~ 6MPa, measuring range. 0.1mg/m3 ~
100mg/m3. If the over-sampling filter trap and capture system can withstand higher pressure, the pressure measurement may be appropriate to increase
Its corresponding pressure.
This standard does not address all of the safety issues related to its application. Before using this standard, the user has the responsibility to develop appropriate safety and
Protective measures, and clarify the scope of its qualified.

3 Terms and Definitions
The following terms and definitions apply to this document.
Particulate matter particles
Removing the water adhering solid particles larger than 0.5μm, including particulate matter adsorbed dried evaporates without a trace
Points are treated as particles.
4 Test principle
A volume of natural gas is retained by the filter constant weight of particulate matter on the filter, after drying weighed according particulate mass and pass
The volume of natural gas over the calculated particle content, in units of mg/m3.
