9、 (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 committee. International organizations,
10、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 with the rules given in the ISO/
11、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 approval by at least 75 % of the me
12、mber 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 3815-2 was prepared by Technical Committee ISO/TC 18, Zinc and zinc a

16、TIONAL STANDARD ISO 3815-2:2005(E) ISO 2005 All rights reserved 1 Zinc and zinc alloys Part 2: Analysis by inductively coupled plasma optical emission spectrometry 1 Scope This part of ISO 3815 specifies analytical methods for determining the chemical composition of zinc and zinc alloys in accordanc
17、e with ISO 301 and ISO 752 by inductively coupled plasma optical emission spectrometry. This part of ISO 3815 includes provisions for preparation of test solutions and calibration solutions for zinc and zinc alloys. The ranges specified for each method can be extended and/or adapted for determinatio
18、ns of low concentrations. This part of ISO 3815 can be applied to other elements (e.g. Ni, Cr and Ti). However, such results will need to be carefully checked by taking into account the interferences, the sensitivity, the resolution and the linearity criteria for each instrument and each wavelength.

23、tted by the components of a sample when excited by a plasma NOTE A plasma is a high-temperature emission source generated by an RF field consisting of a mixture of argon atoms, argon ions and electrons. Sample atoms entering the plasma emit light radiation, whose characteristic wavelengths and inten
24、sities are used to identify the elements and determine concentrations, respectively. Samples are usually presented to the plasma in solution form. 4 Principle A sample of the metal or alloy is dissolved in a mixture of nitric and tartaric acid, and after adequate dilution and atomization of the solu
