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.

ASTM D4991-07 用真空法进行空瓶罐泄漏试验的标准试验方法

Containers may be pressurized in accordance with this test method without modification to the closure or to the body of the container. This test method may be used for testing rigid containers intended for the transportation of some liquids by air in accordance with the ICAO TIs or in accordance with the UN TDG. This test method establishes the point at which leakage commences, with a limit of approximately 95-kPa (13.8-psi) differential. See Test Method D 3078 for flexible packages. This test method may not be suitable for some packages, such as packages with paper cap seals, where the test fluid may rapidly deteriorate the packaging. 1.1 This test method covers the testing of empty containers for resistance to leakage under differential pressure conditions such as those which can occur during air transport. It is suitable for testing rigid containers intended for the transportation of some hazardous liquids in accordance with the United Nations Recommendations On The Transport Of Dangerous Goods (UN TDG) and the International Civil Aviation Organization Technical Instructions For The Safe Transport Of Dangerous Goods By Air (ICAO TIs).1.2 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 and health practices and determine the applicability of regulatory limitations prior to use.

ASTM E595-06 在真空环境中除气作用引起的总质量损失和收集到的挥发性可凝聚材料的标准试验方法

1.1 This test method covers a screening technique to determine volatile content of materials when exposed to a vacuum environment. Two parameters are measured: total mass loss (TML) and collected volatile condensable materials (CVCM). An additional parameter, the amount of water vapor regained (WVR), can also be obtained after completion of exposures and measurements required for TML and CVCM. 1.2 This test method describes the test apparatus and related operating procedures for evaluating the mass loss of materials being subjected to 125C at less than 7 103 Pa (5 105 torr) for 24 h. The overall mass loss can be classified into noncondensables and condensables. The latter are characterized herein as being capable of condensing on a collector at a temperature of 25C. Note 1Unless otherwise noted, the tolerance on 25 and 125C is 1C and on 23C is 2C. The tolerance on relative humidity is 5 %.1.3 Many types of organic, polymeric, and inorganic materials can be tested. These include polymer potting compounds, foams, elastomers, films, tapes, insulations, shrink tubings, adhesives, coatings, fabrics, tie cords, and lubricants. The materials may be tested in the "as-received" condition or prepared for test by various curing specifications.1.4 This test method is primarily a screening technique for materials and is not necessarily valid for computing actual contamination on a system or component because of differences in configuration, temperatures, and material processing.1.5 The criteria used for the acceptance and rejection of materials shall be determined by the user and based upon specific component and system requirements. Historically, TML of 1.00 % and CVCM of 0.10 % have been used as screening levels for rejection of spacecraft materials.1.6 The use of materials that are deemed acceptable in accordance with this test method does not ensure that the system or component will remain uncontaminated. Therefore, subsequent functional, developmental, and qualification tests should be used, as necessary, to ensure that the material''s performance is satisfactory.This standard does not purport to address all of the safety concerns associated with its use. 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.
