Metodat e provës për analizën e plumbit në PVC e izolimit dhe veshjes së kabllove elektrik dhe me fibra optik -Metoda A : Përcaktimi I përmbajtjes totale të plumbit me spectrometrinë e absorbimit atomik në eksitim të flakës -Metoda B : Analiza sasiore e plumbit të përftuar nga çngjyrosja e Sulfitit të plumbit

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

Asnjë informacion i shtuar.

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 %.
