Metodat e provës për analizën e përmbajtjes së plumbit në PVC e marë nga izolacioni dhe nga këllëfi i kabllove elektrik dhe ato të fibrave optike - Metoda A: Përcaktimi total i përmbajtjes së plumbit me absorbim spektrometrik të eksitimit atomik me flakë

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 lead sulphide staining

Scope

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 %.
