DIN EN 13890:2010-01 EN 13890:2009 (E) 4 Introduction This European Standard provides a framework fo
22、r assessing the performance of procedures for measuring metals and metalloids against the general requirements for the performance of procedures for measuring chemical agents in workplace atmospheres as specified in EN 482. It enables producers and users of procedures for measuring metals and metall
23、oids in airborne particles to adopt a consistent approach to method validation. Although this European Standard has been written for assessing the performance of procedures for measuring metals and metalloids, it can be used as the basis for assessing the performance of procedures for measuring othe
24、r chemical agents that are present as or in airborne particles, e.g. sulphuric acid mist. DIN EN 13890:2010-01 EN 13890:2009 (E) 5 1 Scope This European Standard specifies performance requirements and test methods for the evaluation of procedures for measuring metals and metalloids in airborne parti
25、cles sampled onto a suitable collection substrate, e.g. a filter. This European Standard specifies a method for estimating the uncertainties associated with random and systematic errors and combining them to calculate the expanded uncertainty of the measuring procedure as a whole, as prescribed in E
26、N 482. This European Standard is applicable to measuring procedures in which sampling and analysis is carried out in separate stages, but it does not specify performance requirements for collection, transport and storage of samples, since these are dealt with in EN 13205 and ISO 15767. This European
27、 Standard is not applicable to procedures for measuring metals or metalloids present as inorganic gases or vapours, e.g. mercury, arsenic (see EN 838 and EN 1076), or to procedures for measuring metals and metalloids in compounds that could be present as a particle/vapour mixture, e.g. arsenic triox

33、issolution, instrumental detection limits are determined by repeat analysis of the calibration blank solution. For all measuring procedures, method detection limits and quantification limits are determined by analysis of laboratory blanks. The determined quantification limits are then assessed again
34、st the performance requirements specified in 5.2.1. Analytical recovery is determined by one of a number of different methods, depending upon the nature of the measuring procedure under evaluation. For measuring procedures for soluble compounds of metals and metalloids, analytical recovery is determ
35、ined by analysis of spiked laboratory blanks (except for procedures that incorporate a design-based sample dissolution method (see A.1.1), for which it is taken to be 100 %). For measuring procedures for total metals and metalloids that involve sample dissolution, analytical recovery is determined b
36、y analysis of pure compounds, reference materials or reference air samples. For measuring procedures for total metals and metalloids that involve analysis of the sample on the collection substrate, analytical recovery is determined by analysis of reference air samples, by the analysis of workplace a
37、ir samples that are characterised by subsequent analysis using a reference procedure or it is estimated from theory. The determined analytical recovery is then assessed against the performance requirements specified in 5.2.2. Measurement uncertainty is estimated using a structured approach. Firstly,
38、 a cause and effect diagram is constructed to identify individual random and non-random uncertainty components of a measuring procedure. After simplification to resolve any duplication, the resulting diagram is used to identify components for which uncertainty estimates are required. Each of these u
39、ncertainty components is then estimated or calculated from experimental data, combined to obtain an estimate of the uncertainty of the measurement method as a whole and multiplied by an appropriate coverage factor to calculate the expanded uncertainty of the method, following the guidance in Annex B
40、. In accordance with 5.2.3, the determined expanded uncertainty is then assessed against the general performance requirements specified in EN 482. 5 Requirements 5.1 Method description 5.1.1 Scope The scope of the measuring procedure shall give at least information about the following: the metals an
41、d metalloids covered by the measuring procedure; the analytical technique(s) used in the measuring procedure; the range of concentrations of metals and metalloids in air for which the measuring procedure has been shown to meet the acceptance criteria for expanded uncertainty prescribed in EN 482, to
42、gether with the associated range of sampled air volumes (e.g. 0,01 mg m-3 to 0,5 mg m-3for sampled air volumes in the range 240 l to 960 l); any form of the metals and metalloids for which the sample preparation method described has been shown to be or is known to be ineffective; and any known inter
43、ferences. NOTE If there is no procedure for measuring a particular metal or metalloid that meets the requirements of this European Standard, a measuring procedure whose performance is nearest to the specified requirements should be used.

46、ncluding suitable and sufficient information on how to minimise their effects, if applicable. 5.1.3 Safety information The measuring procedure shall provide suitable and sufficient information on the safety hazards associated with the reagents and equipment used in the procedure. 5.1.4 Samplers The
47、measuring procedure shall: require the user to select samplers that are designed to collect an appropriate fraction of airborne particles, as defined in EN 481, according to the particle size fraction(s) that is applicable to the limit value for the metals and metalloids of interest (e.g. an inhalab
48、le sampler, a thoracic sampler or a respirable sampler); specify that the samplers shall comply with the provisions of EN 13205; and require, if appropriate, for procedures that do not involve sample dissolution, calibration of the analytical instrument used to be sampler specific, e.g. for X-ray fl
