1 Scope

This standard specifies the organic tin in the electronic components of electronic products Fourier transform infrared spectroscopy (FT-IR) screening method. This standard applies to the electrical and electronic products in the plastic parts of not less than 0.05% of the organic tin screening.

2 normative reference documents

The following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article Pieces. For undated references, the latest edition (including all modifications) applies to this document. Limits for Restricted Substances in Electrical and Electronic Products GB/T 26572-2011

3 principle

Collect the sample of the polymer material for the electrical and electronic products, freeze and crush the organic tin in the sample by adding n-hexane, and then The extract was concentrated. The concentrated extract was added to the potassium bromide chip to collect the infrared spectrum, and it was observed whether the spectrum had organic tin C-Sn bond 630cm-1 ~ 440cm-1 between the characteristics of absorption, to determine whether the sample contains organic tin.
