This European Prestandard (ENV) was approved by CEN on 9 June 2001 as a prospective standard for provisional application.
The period of validity of this ENV 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 ENV can be converted into a European Standard.
CEN members are required to announce the existence of this ENV in the same way as for an EN and to make the ENV available promptly
at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the ENV) until the final
decision about the possible conversion of the ENV into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece,
Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom.

Foreword
This European Prestandard has been prepared by Technical Committee CEN/TC 306, "Lead and lead alloys", the
secretariat of which is held by AFNOR.
CAUTION FOR SAFETY AND TRAINING
The methods in this standard are recommended for the certification of reference materials and as umpire methods
in cases of a dispute. The importance of either application, and the paramount issue of safety, requires that they
should only be carried out by fully-trained analysts who are experienced in all relevant techniques and the
precautions necessary in the inherently hazardous environs of a laboratory, especially those required when using
particularly hazardous apparatus and reagents used in some of these methods.
Where a particular hazard exists, this is given as a DANGER adjacent to the point in the text where the apparatus
or reagent is referenced.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to announce this European Prestandard: Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden,
Switzerland and the United Kingdom.
1 Scope

coupled plasma emission spectrometry (ICP-ES) for the determination of elements at low content in lead for the

wavelength (absorbance);
comparison with that of matrix-matched calibration solutions of the same element.
3.2.2 Inductively coupled plasma emission spectrometry (ICP-ES)

nebulization of the test solution into the plasma of an inductively coupled plasma optical emission
spectrometer;
measurement of the intensity of the emission signal from the spectrum of the element to be determined at the
