1 Scope
This part of GB/T 39560 describes the determination of lead and cadmium in polymers, metals and electronic parts by AAS, AFS, ICP-OES and ICP-MS
And chromium method.
This section specifies the determination of cadmium (Cd), lead (Pb) and chromium (Cr) content in electrical and electronic products. It covers three types of substrates.
Polymer/polymer components, metals and alloys, and electronics.
The samples in this section refer to the objects to be processed and tested. The sample and the method of obtaining it shall be determined by the institution implementing the test. For testing electronics
For further guidance on the content of restricted substances in products and how to obtain representative samples from them, see IEC 62321-2.Selection of samples and/or
The measurement may affect the interpretation of the test results.
This section specifies the determination method of cadmium (Cd), lead (Pb) and chromium (Cr) in electronic and electrical products, and introduces the detection of four instruments
Methods (AAS, AFS, ICP-OES, ICP-MS) and several sample chemical pretreatment methods (preparation of sample solution), you can choose from them
The most suitable method.
Since hexavalent chromium in polymers and electronic parts is sometimes difficult to determine, this section describes chromium in polymers and electronic parts other than AFS
Of screening methods. Chromium analysis can provide information on whether hexavalent chromium is present in the material. However, elemental analysis cannot selectively determine hexavalent
Chromium, it measures the total chromium content in the sample. If the total chromium content exceeds the limit of hexavalent chromium, a confirmation test for hexavalent chromium should be carried out.
The ICP-OES and AAS methods described in this section are more than 10mg/kg Pb, Cd and Cr; or the ICP-MS method
Pb and Cd higher than 0.1 mg/kg; or Pb higher than 10 mg/kg determined by AFS method, and Cd higher than 1.5 mg/kg can be obtained.
Good accuracy and precision. These methods can also test higher content samples.
Because of the stability of the material, this section does not apply to samples containing polyfluoropolymers. If sulfuric acid is used in the analysis, keep it
At the risk of Pb loss, an erroneously low analysis value will be obtained. In addition, because it may interfere with the reduction of Cd, sulfuric acid and hydrofluoric acid do not
It is suitable for the determination of Cd by atomic fluorescence spectrometry.
The dissolution process of the sample has limitations and risks. For example, precipitation of the target or other elements may occur. In this case, the residual
The substance should be checked separately or dissolved by other methods, and then combined with the test sample solution.
