Test methods for analysis of lead in PVC taken from insulation and sheath of electric and optical fibre cables - Method A: Total lead content determination with flame excitation atomic absorption spectrometry - Method B: Qualitative analysis of lead by le
This European Standard describes two methods for the analysis of lead in PVC-insulating and sheathing
materials for electric and for optical fibre cables. The samples of PVC are taken from the finished cable.
Method A provides a quantitative method and Method B provides a qualitative method.
NOTE 1 Users may refer to either Method A or Method B or to both methods.
NOTE 2 Other methods of determination not specified here are known to be capable of achieving equivalent results, but do not
conform to this EN (see “Introduction”).
Both Method A and Method B are applicable to products having a total lead content greater than or equal
to 0,01 %.
