3.4.2 Result of XRF screening
Resultaterne af XRF-screeningen fremgår af Bilag D, XRF-resultater. 
The results of the XRF screening appear from Appendix D, XRF results.
På en enkelt prøve er der lavet to XRF-analyser. 
In one sample two XRF analyses were made.
I udvælgelsen af produkter er der taget hensyn til retningslinierne i DS/EN 71-3 vedr. tilpasning af det analytiske resultat. 
In the selection of products the guidelines in DS/EN 71-3 for adjustment of the analytical result have been taken into consideration.
”Det tilpassede analytiske resultat” opnås ved at fratrække det analytiske resultat en korrektion. 
”The adjusted analytical result” is obtained by deducting a correction from the analytical result.
F.eks. er den analytiske korrektion 30% for Ba. 
E.g. is the analytical correction for Ba 30%.
Den fundne værdi for Ba på 1011 ppm for Leg 34 vil således korrigeret være væsentligt under kravet på 1000 ppm. 
The found value for Ba of 1011 ppm for Toy 34 will thus corrected be considerably below the requirement of 1000 ppm.
Der er derfor ikke lavet migration på Leg 34. 
For this reason no migration analysis was made on Toy 34.

The found contents of Cr and Cd are so low that they do not indicate the use of Cr and Cd-containing pigments in the analysed samples.

Der er ikke noget krav i DS/EN 71-3 til indhold af Ni. 
DS/EN 71-3 comprehends no requirements for the content of Ni.
I nikkel-bekendtgørelsen stilles der krav både til maksimalt indhold samt til afgivelse af nikkel under bestemte betingelser. 
However, the nickel statutory states requirements for both maximum content and release of nickel under certain conditions.
Sammenholdes de fundne værdier i de analyserede prøver, se tabel 3.5, med kravene i nikkelbekendtgørelsen (p.t. under revision), hvor kravet til indhold af nikkel i f.eks. ørestikker er maksimalt 500 ppm ses, at de fundne indhold er væsentligt under. 
A comparison between the values found in the samples analysed, see table 3.5, and the requirements in the nickel statutory (which is being revised at present), where the requirement for content of nickel in e.g. ear stickers is maximum 500 ppm, it can be concluded that the content found is considerably below the allowed value.

Antimon (Sb) anvendes også som flammehæmmer, og bruges tillige sammen med bromerede flammehæmmere. 
A content of Br may indicate a content of brominated flame retardant.

Yet nothing indicates the use of Sb in the analysed samples.
Der er derfor lavet yderligere analyse til identifikation af indhold og type af flammehæmmer i de angivne produkter, se afsnit 3.10 for analyse for bromerede flammehæmmere. 
Therefore the mentioned products were analysed further to identify the content and type of flame retardants, see section 3.10 for analysis for brominated flame retardants.
