ENV 14138:2001

Lead and lead alloys - Analysis by flame atomic absorption spectrometry (FAAS) or inductively coupled plasma emission spectrometry (ICP-ES), after separation by co-precipitation

This European Prestandard specifies methods using flame atomic absorption spectrometry (FAAS) and inductively coupled plasma emission spectrometry (ICP-ES) for the determination of elements at low content in lead for the ranges given in Table 1.
Higher contents than those listed in Table 1 should be determined according to ENV 13800.
These methods are intended as the definitive methods in case of dispute for the determination of elements at low content in lead. They are also recommended for the analysis of Certified Reference Materials (CRM) and Reference Materials (RM) which are used in analysis according to ENV 12908.

Blei und Bleilegierungen - Analyse durch Flammen-Atomabsorptionsspektrometrie (FAAS) oder Emission-Spektrometrie mit induktiv gekoppeltem Plasma (ICP-ES), nach Abtrennung durch Mitfällung

Diese Europäische Vornorm legt ein flammen-atomabsorptionsspektrometrisches Verfahren (FAAS) und ein emissionsspektrometrisches Verfahren mit induktiv gekoppeltem Plasma (ICP-ES) für die Bestimmung niedriger Elementgehalte in Blei fest, deren Bereiche in Tabelle 1 gegeben sind.
Höhere Gehalte als die in Tabelle 1 angegebenen, sollten nach ENV 13800 bestimmt werden.
Diese Verfahren sind vorgesehen als Schiedsverfahren im Falle von Streitigkeiten für die Bestimmung von niedrigen Elementgehalten in Blei. Sie werden ebenfalls empfohlen für die Analyse von zertifizierten Referenzmaterialien (ZRM) und Referenzmaterialien (RM), welche in der Analytik entsprechend ENV 12908 eingesetzt werden.

This European Prestandard (ENV) was approved by CEN on 18 November 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.
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.
CAUTION FOR SAFETY AND TRAINING
The methods in this Prestandard 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.
1 Scope
This European Prestandard specifies methods using flame atomic absorption spectrometry (FAAS) and inductively
coupled plasma emission spectrometry (ICP-ES) for the determination of elements at low content in lead for the
ranges given in Table 1.
Higher contents than those listed in Table 1 should be determined according to ENV 13800.
