This Technical Specification (CEN/TS) was approved by CEN on 12 September 2006 for provisional application.
The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.
CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available
promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)
until the final decision about the possible conversion of the CEN/TS into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France,
Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania,
Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

Foreword
This document (CEN/TS 15022-4:2006) has been prepared by Technical Committee CEN/TC 133 “Copper and
copper alloys”, the secretariat of which is held by DIN.
Within its programme of work, Technical Committee CEN/TC 133 requested CEN/TC 133/WG 10 "Methods of
analysis" to prepare the following Technical Specification:
CEN/TS 15022-4, Copper and copper alloys — Determination of tin content — Part 4: Medium tin content — Flame
atomic absorption spectrometry method (FAAS)
This is one of four parts of the standard/technical specification for the determination of tin content in copper and
copper alloys. The other parts are:
prEN 15022-1, Copper and copper alloys — Determination of tin content — Part 1: Titrimetric method
prEN 15022-2, Copper and copper alloys — Determination of tin content — Part 2: Spectrometric method
EN 15022-3, Copper and copper alloys — Determination of tin content — Part 3: Low tin content — Flame atomic
absorption spectrometry method (FAAS)
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to announce this Technical Specification: Austria, Belgium, Cyprus, Czech Republic, Denmark,
Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta,

1 Scope
This Technical Specification specifies a flame atomic absorption spectrometric method (FAAS) for the determina-
tion of the tin content of copper and copper alloys in the form of unwrought, wrought and cast products.
The method is applicable to products having medium tin mass fractions between 0,2 % and 3 %.
2 Normative references
The following referenced documents are indispensable for the application of this European Technical Specification.
For dated references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 1811-1, Copper and copper alloys — Selection and preparation of samples for chemical analysis — Part 1:
Sampling of cast unwrought products
ISO 1811-2, 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 in hydrochloric acid and hydrogen peroxide followed, after suitable dilution, by aspira-
tion into a nitrous oxide/acetylene flame of an atomic absorption spectrometer. Measurement of the absorption of
the 286,3 nm line emitted by a tin hollow-cathode discharge lamp.
4 Reagents and materials
4.1 General
During the analysis, use only reagents of recognized analytical grade and only distilled water or water of equivalent
purity.
4.2 Hydrochloric acid, HCl (ρ = 1,19 g/ml)
4.3 Hydrochloric acid solution, 7 + 3
Dilute 700 ml of hydrochloric acid (4.2) in 300 ml of water.
4.4 Hydrogen peroxide, H O 30 % (mass fraction) solution, free from tin base stabilizers
2 2
Hydrogen peroxide may be stabilized by products containing some tin. It is therefore necessary to use exactly the
same volume of hydrogen peroxide for the dissolution of the test sample as for the preparation of the calibration so-
lution.
4.5 Tin stock solution, 1 g/ l Sn
Weigh (1 ± 0,001) g of tin (Sn ≥ 99 %) and transfer it into a 250 ml beaker. Dissolve it in 100 ml hydrochloric acid
(4.2) and several drops of hydrogen peroxide (4.4) and cover with a watch glass. Heat gently until the metal is dis-
solved. Cool to room temperature and transfer the solution quantitatively into a 1 000 ml one-mark volumetric flask.
Dilute to the mark with water and mix well.
1 ml of this solution contains 1 mg of Sn.
4.6 Copper base solution, 20 g/l Cu
Weigh 10,0 g of electrolytic copper (Cu ≥ 99,95 %) into a 600 ml beaker. Add 250 ml of the hydrochloric acid
solution (4.3) and cover with a watch glass. Cool and add successively 5 ml hydrogen peroxide portions (4.4) until
dissolution is complete, waiting after each addition until all effervescence ceases. Heat to eliminate the excess hy-
drogen peroxide. Cool and transfer this solution quant
