ASTM E834 Standard Practice for Determining the Gaseous Environment of a Vacuum Chamber Using a Cold Finger

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ASTM E834 testing. This application covers the technique of collecting samples from materials that are part of the residual gas environment of an evacuated vacuum chamber. The practice uses a device called a "cold finger", which is placed inside the sample medium and cooled so that the components of the medium are held on the cold finger surface.

The application includes a method for sampling the cold finger and determining the weight of the material removed from the cold finger. The app includes recommendations for ways the sample can be analyzed to identify the components that make up the sample.

By identifying the species that make up the sample, the app can be used to help identify the source of the components and whether the sample is often similarly representative of samples obtained from the vacuum chamber. This application covers alternative approaches and uses to which the application can be applied. The degree of molecular flow anisotropy significantly affects the assurance that the properties determined by this procedure can be attributed to the vacuum chamber environment in general.

Values ​​stated in SI units should be accepted as standard. No other units of measurement are included in this standard.

This standard does not purport to address all, if any, safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory restrictions prior to use.

This international standard has been developed in accordance with the internationally accepted principles of standardization set out in the resolution on Principles for the Development of International Standards, Guidelines and Recommendations published by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
