15、ion 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 been established has the right to be represented on that committe

16、e. 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 standardization. International Standards are drafted in accordance

17、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 circulated to the member bodies for voting. Publication as an International Standard requires app

18、roval 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 responsible for identifying any or all such patent rights. ISO 30011 was prepared by Technical Commi

BS ISO 30011:2010ISO 30011:2010(E) ISO 2010 All rights reserved vIntroduction The health of workers in many industries is at risk through exposure by inhalation of toxic metals and metalloids. Industrial hygienists and other pub

20、lic health professionals need to determine the effectiveness of measures taken to control workers exposure, and this is generally achieved by taking workplace air measurements. ISO 30011 has been published in order to make available a method for making valid ultra-trace exposure measurements for a w

21、ide range of metals and metalloids in use in industry. It is intended for: agencies concerned with health and safety at work; industrial hygienists and other public health professionals; analytical laboratories; and industrial users of metals and metalloids and their workers. ISO 30011 specifies a m

22、ethod for determination of the mass concentration of metals and metalloids in workplace air using quadrupole inductively coupled plasma mass spectrometry (ICP-MS). For many metals and metalloids, analysis by ICP-MS is advantageous when compared to methods such as inductively coupled plasma atomic em

23、ission spectrometry, due to its sensitivity and the presence of fewer spectral interferences. ISO 30011 gives requirements and test methods for analysis of sample solutions by ICP-MS. Users of ISO 30011 are referred to ISO 15202-1 for collection of samples of airborne particulate matter and to ISO 1

24、5202-2 for procedures for preparing sample solutions for analysis by ICP-MS. It has been assumed in the drafting of ISO 30011 that the execution of its provisions, and the interpretation of the results obtained, are entrusted to appropriately qualified and experienced people.

26、ductively coupled plasma mass spectrometry (ICP-MS) for analysing test solutions prepared from samples of airborne particulate matter collected as specified in ISO 15202-1. Method development, performance checks, and a routine analysis method are specified. Test solutions for analysis by this Intern

27、ational Standard are prepared as specified in ISO 15202-2. This International Standard is applicable to the assessment of workplace exposure to metals and metalloids for comparison with limit values (see e.g. EN 68910, ASTM E13708). The following is a non-exclusive list of metals and metalloids for

28、which limit values have been set (see Reference 15) and for which one or more of the sample preparation methods specified in ISO 15202-2 and the analytical procedure described in this International Standard are applicable. However, there is no information available on the effectiveness of any of the

30、 sodium zirconium boron hafnium nickel tellurium cadmium indium niobium thallium calcium iron phosphorus tin This International Standard is not applicable to determination of elemental mercury, since mercury vapour is not collected using the sampling method specified in ISO 15202-1. The procedure is

31、 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 l min1for sampling times in the range 0,5 h to 8 h and for assessment of exposure against the short-term exposure limits, where appl

32、icable. The procedure is subject to no significant spectral interferences (see A.3), provided that suitable analytical isotopes are used. However, inadequate matrix-matching can adversely affect results. BS ISO 30011:2010ISO 30011:2010(E) 2 ISO 2010 All rights reserved2 Normative references The foll
