Foreword ISO (the Intern
14、ational Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has b
15、een 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 the International Electrotechnical Commission (IEC) on all matters of electrotechnical sta
16、ndardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at l
17、east 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this part of ISO 15202 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 15202-1 was prepar
18、ed by Technical Committee ISO/TC 146,Air quality, Subcommittee SC 2,Workplace atmospheres.

20、e health of workers in many industries is at risk through exposure by inhalation of toxic metals and metalloids. Industrial hygienists and other public health professionals need to determine the effectiveness of measures taken to control workers exposure, and this is generally achieved by taking wor
21、kplace air measurements. This part of ISO 15202 has been published in order to make available a method for making valid exposure measurements for a wide range of metals and metalloids in use in industry. It will be of benefit to: agencies concerned with health and safety at work; industrial hygienis
22、ts and other public health professionals; analytical laboratories; industrial users of metals and metalloids and their workers, etc. This part of ISO 15202 specifies a generic method for determination of the mass concentration of metals and metalloids in workplace air using inductively coupled plasm
23、a atomic emission spectrometry (ICP-AES). This part of ISO 15202 gives details of relevant International, European and National Standards which specify characteristics, performance requirements and test methods relating to sampling equipment. It augments guidance provided elsewhere on assessment str
24、ategy and measurement strategy, and specifies a method for collecting samples of airborne particulate matter for subsequent chemical analysis. Part 2 of ISO 15202 describes a number of procedures for preparing sample solutions for analysis by ICP-AES. Part 3 of ISO 15202 gives requirements and test
25、methods for analysis of sample solutions by ICP-AES. It has been assumed in the drafting of this part of ISO 15202 that the execution of its provisions, and the interpretation of the results obtained, is entrusted to appropriately qualified and experienced people.

27、 air Determination of metals and metalloids in airborne particulate matter by inductively coupled plasma atomic emission spectrometry Part 1: Sampling 1Scope 1.1This part of ISO 15202 specifies a method for collecting samples of airborne particulate matter for subsequent determination of metals and
28、metalloids using inductively coupled plasma - atomic emission spectrometry. 1.2The method is not applicable to the sampling of mercury, which is present in air in the vapour phase at ambient temperatures; inorganic compounds of metals and metalloids that are permanent gases, e.g. arsine (AsH3); or i
29、norganic compounds of metals and metalloids that are present in the vapour phase at ambient temperatures, e.g. arsenic trioxide (As2O3). NOTEAlthough the method does not describe a means of collecting inorganic compounds of metals and metalloids that are present in the vapour phase, in most instance
30、s this is relatively easily achieved by using a back-up filter which has been pre- treated to trap the compound(s) of interest, e.g. a back-up paper pad impregnated with sodium carbonate is suitable for collecting arsenic trioxide (see ISO 11041). 1.3The method is applicable to personal sampling of
31、the inhalable or respirable fraction of airborne particles, as defined in ISO 7708, and to static sampling. 2Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO 15202.
