12、5202-1:2012ISO 15202-1:2012(E)ForewordISO (the International 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 interest

13、ed in a subject for which 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 the International Electrotechnical Co

14、mmission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technic

15、al committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shal

16、l not be held responsible for identifying any or all such patent rights.ISO 15202-1 was prepared by Technical Committee ISO/TC 146, Air quality, Subcommittee SC 2, Workplace atmospheres.This second edition cancels and replaces the first edition (ISO 15202-1:2000), which has been technically revised.

17、 The major changes in the second edition are as follows: definitions have been updated; a new Annex A has been added to provide guidance regarding sampler wall deposits.ISO 15202 consists of the following parts, under the general title Workplace air Determination of metals and metalloids in airborne

18、 particulate matter by inductively coupled plasma atomic emission spectrometry: Part 1: Sampling Part 2: Sample preparation Part 3: Analysisiv ISO 2012 All rights reservedBS ISO 15202-1:2012ISO 15202-1:2012(E)IntroductionThe health of workers in many industries is at risk through exposure by inhalat

19、ion 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 workplace air measurements. This part of ISO 15202 has been published in order t

20、o 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 hygienists and other public health professionals; analytical laboratories; industrial

21、 users of metals and metalloids and their workers, etc.This part of ISO 15202 specifies a generic sampling method for subsequent determination of the mass concentration of metals and metalloids in workplace air using inductively coupled plasma atomic emission spectrometry (ICP-AES). Samples obtained

22、 using the method described herein can also be subsequently analysed by other instrumental methods, such as atomic absorption spectrometry (AAS) or inductively coupled plasma mass spectrometry (ICP-MS).This part of ISO 15202 gives details of relevant International, European and National Standards wh

23、ich specify characteristics, performance requirements and test methods relating to sampling equipment. It augments guidance provided elsewhere on assessment strategy and measurement strategy, and specifies a method for collecting samples of airborne particulate matter for subsequent chemical analysi

24、s.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 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 pr

25、ovisions, and the interpretation of the results obtained, is entrusted to appropriately qualified and experienced people.

26、sma atomic emission spectrometry Part 1: Sampling1 Scope1.1 This part of ISO 15202 specifies a method for collecting samples of airborne particulate matter for subsequent determination of metals and metalloids using inductively coupled plasma atomic emission spectrometry (ICP-AES). Samples obtained

27、using the method described herein can also be subsequently analysed for elemental composition by other instrumental methods, such as atomic absorption spectrometry (AAS) or inductively coupled plasma mass spectrometry (ICP-MS).1.2 The method is not applicable to the sampling of mercury, which is pre

28、sent in air in the vapour phase at ambient temperatures; inorganic compounds of metals and metalloids that are permanent gases, e.g. arsine (AsH3); or inorganic compounds of metals and metalloids that are present in the vapour phase at ambient temperatures, e.g. arsenic trioxide (As2O3).NOTE Althoug

29、h the method does not describe a means of collecting inorganic compounds of metals and metalloids that are present in the vapour phase, in most instances 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

30、pad impregnated with sodium carbonate is suitable for collecting arsenic trioxide (see ISO 110412).1.3 The method is applicable to personal sampling of the inhalable or respirable fraction of airborne particles, as defined in ISO 7708, and to static sampling.2 Normative referencesThe following refer
