ISO 21360:2007 真空技术.测量真空泵性能的标准方法.一般描述

This International Standard is a basic standard which defines three different methods for measuring the volume flow rate and one method each for measuring the base pressure, the compression ratio and the critical backing pressure of a vacuum pump. The first method for measuring the volume flow rate (the throughput method) is the basic concept, in which a steady gas flow is injected into the pump while the inlet pressure is measured. In practice, the measurement of gas throughput may be complicated or inexact. For this reason, two other methods are described which avoid the direct measurement of throughput. The second method for measuring the volume flow rate (the orifice method) is used when there is very small throughput occurring at very small inlet pressures (in the high and ultra-high vacuum). It is based on measuring the ratio of pressures in a two-chamber test dome where the two chambers are separated by a wall with a circular orifice. The third method for measuring the volume flow rate (the pump-down method) is well-suited for automated measurement. It is based on the evacuation of a large vessel. The volume flow rate is calculated from two pressures, before and after a pumping interval, and from the volume of the test dome. Different effects, such as leak and desorption rates, gas cooling by nearly isentropic expansion during the pumping interval and increasing flow resistance in the connection line between test dome and pump caused by molecular flow at low pressures, influence the results of the pressure measurement and the resulting volume flow rate. The choice of the required measurement methods depends on the properties of the specific kinds of vacuum pump, e.g. the measurement of the critical backing pressure is only necessary for vacuum pumps which need a backing pump. All data that is measured on a vacuum pump but not described in this International Standard (e.g. measurement of power consumption) is defined in the specific pump standard.

This Technical Specification lays down the physical, technical and metrological conditions to be fulfilled when calibrations of vacuum gauges are performed by direct comparison with a reference gauge. From the conditions described can be deduced how to design an apparatus that can perform vacuum gauge calibrations in an adequate manner. The vacuum gauges to be calibrated can be of any kind. Many types of gauges consist of several parts. Typically, these are gauge head, cable, operational device and signal read out. This whole set is considered as the unit that has to be calibrated. Whereas, if only the gauge head (i.e. that part of the vacuum gauge directly exposed to the vacuum) is calibrated, all set-ups and conditions would have to be recorded such that the user of the calibrated gauge head would be able to perform the measurements in the same manner as during the calibration. The reference gauge is either a calibrated gauge traceable to a vacuum primary or national standard (normal case), with a calibration certificate according to ISO/IEC 17025, or an absolutely measuring instrument (rare case), traceable to the SI units and to which a measurement uncertainty can be attributed. This Technical Specification does not give guidance on how to treat special types of vacuum gauges, be they reference standards or units under calibration, and it is intended that such guidance be given in other technical specifications. The pressure range for calibrations treated in this Technical Specification depends on the realised design of the calibration apparatus and on the type of reference gauge. The range varies in its limits from 10 Pa to 110 kPa.
