oem so2 leak rate For determining the quality

Leak Rate is therefore the volume of material (air, fluid etc.) that escapes from a closed or sealed containment in a predetermined amount of time. You may see leak rate expressed in various units of measure, such as cc/min, cc/sec, or ft3/hr. The units will generally reflect whether you are measuring a relatively high or low leak rate; for

  • Test Method: Method 6 Determination of Sulfur Dioxide

    check after the sampling run is mandatory. The leak-check procedure is as follows: Temporarily attach a suitable (e.g., 0- to 40-cc/min) rotameter to the outlet of the dry gas meter, and place a vacuum gauge at or near the probe inlet. Plug the probe inlet, pull a vacuum of at least 250 mm (10 in.) Hg and note the flow rate as indicated

  • Sulfur Dioxide Basics | Sulfur Dioxide (SO2) Pollution | US EPA

    EPA’s national ambient air quality standards for SO 2 are designed to protect against exposure to the entire group of sulfur oxides (SO x ). SO 2 is the component of greatest concern and is used as the indicator for the larger group of gaseous sulfur oxides (SO x ). Other gaseous SO x (such as SO 3) are found in the atmosphere at concentrations much lower than SO 2 .

  • How to Establish an Acceptable Leak Rate

    • The characteristics of the hole (or leak) that determine whether it will leak are the smallest diameter in the hole path, the path length of the hole through the part material, surface tension, and the surface finish of hole (leak). Hole Size - The smallest opening in the flow (leak) path controls the rate of flow through the path.
