The work of preparing International Standards is normally carried out through ISO and IEC technical committees. Each member body interested in a subject for whic
8、h a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with IEC on all matters of electrotechnical standardization.

15、ive electronic devices and systems which are covered by other International Standards, electrostatic charging of clothing can also cause problems of clinging, uncomfortable shocks and the attraction of airborne dust and other contaminants. Clothing designed to avoid airborne dust contamination is re
16、quired in a number of expanding industries relating to precision technology, biotechnology, food, hygiene, etc. It is also generally desirable to have clothing that does not cling or cause uncomfortable shocks. Test methods are required to evaluate the propensity of fabrics used to make clothing des
17、igned to avoid problems associated with electrostatic charging. Test methods are specified in a number of National and International Standards, including those published by ISO and IEC. However, the relationship between measurable electrostatic properties and end use performance is rather complex an
18、d may require a combination of different test methods depending on application. The test method described in this International Standard is one of a number of test methods that can be used to evaluate the electrostatic propensity of textile materials. Definitive performance requirements are not give
19、n, but guidance on the interpretation of results is given in informative Annex A. The qualitative interpretation scheme is based on anecdotal experience in industry in controlling clinging, uncomfortable shocks and attraction of particulate contaminants. Nevertheless, it is provided for guidance onl
20、y and users of this International Standard are advised to check its validity for their own applications.

28、by means of corona discharge created by a sharply pointed electrode 3.6 conductive providing a sufficiently high conductivity so that potential differences over any parts of a material or object are not sufficiently large as to be of practical significance Note 1 to entry: In general, a conductive m
29、aterial has a resistance below about 10 5 but different standards may define different resistance ranges for this term. 3.7 c onduc t i ve f ibr e fibre in which conductive components are included Note 1 to entry: If conductive components are exposed at the surface, the fibre is called surface condu
30、ctive fibre. If the conductive components are completely embedded in non-conductive polymer, the fibre is called core conductive fibre. 4 Principle A fabric specimen is charged by corona charging and the peak value of the impressed voltage is obtained immediately after the application of high voltag
31、e is stopped. The impressed voltage on the specimen decays towards zero, but not necessarily down to zero. The electrostatic propensity of the test specimen is quantified by determining the peak voltage value and the half decay time, or decay time to some other percentage. 5 Conditioning and testing
32、 atmosphere Unless otherwise agreed or specified, the atmosphere for conditioning and testing shall be a temperature of (20 2) C and a relative humidity of (40 4) %. If a different temperature or humidity is used for conditioning or testing, record it in the test report. NOTE The measurements of tem
33、perature and humidity are specified in ISO 139. 6 Apparatus 6.1 General One possible test apparatus is shown below as an example. Other apparatus capable of measuring impressed peak voltage and charge decay time from corona charged specimens may also be used after appropriate validation. 6.2 Test ap
34、paratus The apparatus is composed of the following parts. Emitter, shown in Figure 1 and Figure 2, a needle type, applied voltage of (10 1) kV, negative polarity.
