15、2004iv Foreword ISO (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 interested in a subject for wh
16、ich 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 Commission (IEC) on all
17、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 technical committees are ci
18、rculated 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 shall not be held respo
19、nsible for identifying any or all such patent rights. ISO 15202-3 was prepared by Technical Committee ISO/TC 146, Air quality, Subcommittee SC 2, Workplace atmospheres. ISO 15202 consists of the following parts, under the general title: Workplace air Determination of metals and metalloids in airborn
20、e particulate matter by inductively coupled plasma atomic emission spectrometry: Part 1: Sampling Part 2: Sample preparation Part 3: Analysis BSISO152023:2004 vIntroduction The health of workers in many industries is at risk through exposure by inhalation to toxic metals and metalloids. Industrial h
21、ygienists and other public health professionals need to determine the effectiveness of measures taken to control workers exposure and this is generally achieved by making workplace air measurements. This part of ISO 15202 has been published in order to make available a method for making valid exposu
22、re 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 users of metals and metalloids and their workers
23、, 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 plasma atomic emission spectrometry (ICP-AES) and gives requirements and test methods for analysis of sample solutions. Part 1 of I
24、SO 15202 gives details of relevant international, European and national standards which specify characteristics, performance requirements and test methods relating to sampling equipment; augments guidance provided elsewhere on assessment strategy and measurement strategy; and specifies a method for
25、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. It has been assumed in the drafting of this part of ISO 15202 that the execution of its provisions and the
26、interpretation of the results obtained are entrusted to appropriately qualified and experienced people.

27、ectrometry Part 3: Analysis 1 Scope This part of ISO 15202 specifies a procedure for the use of inductively coupled plasma atomic emission spectrometry for analysing test solutions prepared as prescribed in ISO 15202-2 from samples of airborne particulate matter collected as specified in ISO 15202-1
28、. Method development, performance checks and a routine analysis method are specified. This part of ISO 15202 is applicable for the assessment of workplace exposure to metals and metalloids for comparison with limit values (see e.g. EN 689 1 , ASTM E 1370 2 , etc.). The following is a non-exclusive l
29、ist of metals and metalloids for which limit values have been set (see Reference 3), and for which one or more of the sample dissolution methods specified in ISO 15202-2 and the analytical procedure described in this part of ISO 15202 are applicable. However, there is no information available on the
30、 effectiveness of any of the sample dissolution methods specified in ISO 15202-2 for those elements in italics. aluminium calcium magnesium selenium tungsten antimony chromium manganese silver uranium arsenic cobalt mercury sodium vanadium barium copper molybdenum strontium yttrium beryllium hafnium
31、 nickel tantalum zinc bismuth indium phosphorus tellurium zirconium boron iron platinum thallium caesium lead potassium tin cadmium lithium rhodium titanium NOTE ISO 15202 is not applicable to determination of elemental mercury, since mercury vapour is not collected using the sampling method specifi
32、ed in ISO 15202-1. The procedure is suitable for assessment of exposure against the long-term exposure limits for most of the metals and metalloids listed above when sampling at a typical flow rate of 2 lmin 1for sampling times in the range 30 min to 8 h and for assessment of exposure against the sh
33、ort-term exposure limits, where applicable (see 10.4). The procedure suffers from no significant spectral interferences (see 10.5), provided that suitable analytical wavelengths are used. However, inaccurate background correction and/or inadequate matrix-matching can adversely affect results. BSISO1
