1 Scope

This part of GB/T 39560 stipulates the screening and analysis of lead, mercury, cadmium, total content in homogeneous materials of electronic and electrical products by X-ray fluorescence spectrometry:

Procedures for five substances of chromium and total bromine:

This section applies to polymers, metals and ceramic materials: This section also applies to raw materials, single materials taken from products, and

A homogenized mixed material composed of more than one material: Any XRF spectrometer that meets the performance specified in this section can be used for sample screening:

However, not all types of XRF spectrometers are suitable for screening and analyzing samples of all sizes and shapes, so they should be carefully selected for specific

XRF spectrometer for screening analysis:

The performance of the testing method in this part has passed the following substances in the content ranges listed in the different matrix materials listed in Table 1~Table 5:
