ASTM D1142 PDF

Product Description Determines the water vapor content of gaseous fuels by measurement of the dew point temperature, followed by calculation of the water. Hi, I´m just needing the ASTM D Standard Test Method for Water Vapor Content of Gaseous Fuels by Measurement of Dew-Point Temperature I´m just. accordance with ASTM D Hydrocarbon Dew point is dependent on pressure, temperature and the composition of the gas. The heavier compounds will.

When this occurs, it is sometimes very helpful to supplement the apparatus in Fig. 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 to use. Excess water vapor can cause corrosive conditions, degrading pipelines and equipment. At d112 temperatures an ice point rather than a water dew point likely will be observed.

What are your requirements. The minimum dew point of any vapor that can be observed is limited by the mechanical parts of the equipment. The chamber is chilled by refrigerant following through the outer cooling jacket, preventing any refrigerant contact with the test sample.

What is your application? Note 1 — Some gaseous fuels contain vapors of hydrocarbons or other components astn easily condense into liquid and sometimes interfere with or mask the water dew point.

However, if the dew point of the condensable hydrocarbons awtm higher than the water vapor dew point, when such hydrocarbons are present in aatm amounts, they may flood the mirror and obscure or wash off the water dew point.

With this attachment it is possible, in some cases, to observe separate condensation points of water vapor, hydrocarbons, and glycolamines as well as ice points. Water—vapor content also affects the heating value d142 natural gas, thus influencing the quality of the gas.
