Abstract
This test method establishes the apparatuses required, calibration and precision of the devices to be used, and the standard procedures for determining the measured speed, or volumetric flow rate, of oil diffusion pumps. This method shall make use of test dome, gage attachment or connecting line, flow-measuring devices, and leak control valve. The pump under test shall be fitted with a test dome of specified design. Gas is then admitted to the test dome in a specified manner at a measured rate, and the resulting change in equilibrium pressure is measured in the specified way.
Scope
1.1 This test method covers the determination of the measured speed (volumetric flow rate) of oil diffusion pumps.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
