QC/T 943-2013 (English Version) PDF

Scope: This standard specifies the detection methods for lead and cadmium content in automotive materials. "X-ray fluorescence spectrometry" is suitable for screening and quickly determining the content of lead and cadmium in automotive materials. "Determination of lead and cadmium in steel, copper and copper alloys, aluminum and aluminum alloy materials by photoelectric direct reading spectrometry" is suitable for quantitative detection of lead in steel, copper and copper alloys, aluminum and aluminum alloy rod or block materials in automobile materials. , the content of cadmium. "Atomic absorption spectrometry, inductively coupled plasma atomic emis ion spectrometry or inductively coupled plasma mass spectrometry for determination of lead and cadmium content in automotive materials" is suitable for quantitative detection of lead and cadmium content in automotive materials.
