Content DescriptionISO 15202-3:2004 prescribes 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 prescribed in ISO 15202-1. Method development, performance checks and a routine analysis method are prescribed. The procedure suffers from no significant spectral interferences, provided that suitable analytical wavelengths are used. However, inaccurate background correction and/or inadequate matrix-matching can adversely affect results. ISO 15202-3:2004 is applicable to the following non-exclusive list of metals and metalloids for which limit values have been set; however, there is no information available on the effectiveness of any of the sample dissolution methods specified in ISO 15202-2 for those elements in italics: aluminium, antimony, arsenic, barium, beryllium, bismuth, boron, caesium, cadmium, calcium, chromium, cobalt, copper, hafnium, indium, iron, lead, lithium, magnesium, manganese, mercury, molybdenum, nickel, phosphorus, platinum, potassium, rhodium, selenium, silver, sodium, strontium, tantalum, tellurium, thallium, tin, titanium, tungsten, uranium, vanadium, yttrium, zinc and zirconium. ISO 15202-3:2004 is not applicable to determination of elemental mercury, since mercury vapour is not collected using the sampling method specified in ISO 15202-1. The results obtained may be used for the assessment of workplace exposure to metals and metalloids for comparison with limit values. About ISOISO, the International Organization for Standardization, brings global experts together to agree on the best way of doing things – for anything from making a product to managing a process. As one of the oldest non-governmental international organizations, ISO has enabled trade and cooperation between people and companies all over the world since 1946. The International Standards published by ISO serve to make lives easier, safer and better. |
