Lidhje nikeli – Përcaktimi i përmbajtjes gjurmë-element me metodën spektrometrike të përthithjes atomike elektrotermike - Pjesa 1: Kërkesa të përgjithshme dhe shpërbërja e mostrës

Nickel alloys — Determination of trace-element content by electrothermal atomic absorption spectrometric method — Part 1: General requirements and sample dissolution

Scope

Specifies electrothermal atomic absorption methods for the determination of trace elements in nickel alloys, in the concentration ranges given in clause 1 of other parts of ISO 11437. Gives in annex B typical compositions of some nickel alloys. Specifies the general requirements for analysis by electrothermal atomic absorption spectrometry, preparation and dissolution of the test sample, method of calculation and the procedures used for the evaluation of the repeatability and reproducibility of the individual methods specified in other parts of ISO 11437.
