BS 15605:2010 pdf download – Copper and copper alloys — Inductively coupled plasma optical emission spectrometry 1 Scope This European Standard specifies six inductively coupled plasma emission spectrometry methods (A to F) for the determination of alloying elements and impurities in copper and copper alloys in the form of unwrought, wrought and cast products. A complementary method, for the analysis of Copper-tin-lead alloys, is described in Annex B (informative). The precision criteria concerning this method do not reach the suitable level, for all the elements specified (zinc and phosphorus, namely). These methods are applicable to the elements listed in Tables 1 to 6 within the composition ranges shown: NOTE 1 The ranges specified for each method can be extended or adapted, for the determination of lower mass frac- tions. NOTE 2 Other elements may be included. However such elements and their mass fractions should be carefully checked, taking into account interference, sensitivity, resolution and linearity criteria for each instrument and each wavelength. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 1 81 1 -1 , Copper and copper alloys — Selection and preparation of samples for chemical analysis — Part 1: Sampling of cast unwrought products ISO 1 81 1 -2, Copper and copper alloys — Selection and preparation of samples for chemical analysis — Part 2: Sampling of wrought products and castings 3 Principle Dissolution of a test portion with hydrochloric and nitric acids. After suitable dilution and addition of an internal reference element, nebulization of the solution into an inductively coupled plasma emission spectrometer and measurement of the intensity of the emitted light, including that of the internal reference element. 4 Reagents During the analysis, use only reagents of recognised analytical grade and only distilled water or water of equivalent purity. The same reagents should be used for the preparation of calibration solutions and of sample solutions. 4.1 Hydrochloric acid, HCl (ρ = 1 ,1 9 g/ml) 4.2 Hydrochloric acid, solution 1 + 1 Add 500 ml of hydrochloric acid (4.1 ) to 500 ml of water. 4.3 Nitric acid, HNO 3 (ρ = 1 ,40 g/ml) 4.4 Nitric acid, solution 1 + 1 Add 500 ml of nitric acid (4.3) to 500 ml of water. 4.5 Hydrofluoric...
